iOS 16 Wallet: expanding the Apple Pay experience, aka Suica auto-charge for the rest of us

iOS 15 added big new features to Wallet, expanding digital keys from cars to include home, office and hotels and ID in Wallet driver licenses for the first time. There were smaller but important UI changes too. A new add card screen offered new categories making is easy to add transit cards regardless of the device region and quickly re-add previous Wallet items from iCloud. iOS 15 was all about Wallet to the extent that Apple now advertises it as a separate thing from Apple Pay with a separate web page, and even referred to Apple Pay as “one of the most important areas of Wallet” in the WWDC keynote. Very interesting.

iOS 16 moves the focus back to Apple Pay and making digital payments more useful, practical and universal. The WWDC22 Keynote announced Apple Pay Later, in-app ID card verification and key sharing. Apple Pay Later is one aspect of several new Apple Pay functions unveiled in the What’s new in Apple Pay and Wallet session.

Multi-merchant payments: In our online world we can never be sure how many sub-merchants are involved when we order something and how our card information is shared. In multi-merchant Apple Pay, multiple payment tokens are issued for each merchant in the same transaction, preserving user privacy, with the iOS 16 Apple Pay paysheet showing a breakdown of each sub-merchant charge. This feature works mostly on the backend, but showcases how smartly the Apple Pay Wallet team design features to ‘just work’ securely for merchants and customers.

Automatic Payments
My favorite iOS 16 feature as it addresses a lot of interesting use cases, much more than just Apple Pay Later installments which fall under:

Reoccurring payments, which include things like installments and subscriptions, basically any regularly scheduled payment. With the recent Starbucks Japan price increases, I decided to sign up for the new JR East Beck’s Coffee Shop subscription plan. Up to 3 cups a day for ¥2,800 a month. A pretty good deal for commuters like me. The Beck’s subscription service is subcontracted out to an interesting online business venture company called Favy that uses Sign in with Apple to create an account. Payment however is manual credit card entry with the onerous, ubiquitous 3D Secure sign-in. Pass issue and serving size selection (M=¥50, L=¥100 extra) is done in Safari. It works well enough, but canceling or getting payment details is a real Safari expedition. It would be a much better, and faster, customer experience doing it all in Apple Pay.

Automatic Reload: this is the real money feature for me because it plays on the classic snag of using Apple Pay Suica…recharge. All pre-paid cards are a catch-22. Japanese users love them because they like the “I know how much money I’m adding to my card” aspect of manual recharge, but there’s the inevitable, you know you forgot about it, bing-bong ‘please recharge’ transit gate alarm when Suica balance is short.

JR East offers Suica Auto-Charge (auto-reload) as a feature of their VIEW card. The auto-charge option works great with Apple Pay Suica but like all transit card auto-charge, it is tethered to the transit gate NFC system. This means the users gets instant, seamless auto-charge but only on the operator’s transit gates. Suica auto-charge does not work outside of the Suica and PASMO transit gates, not at store terminals, not in other transit card regions like JR West ICOCA. This limitation is a big customer complaint, I and many others would love Apple Pay Suica auto-charge to work everywhere.

Apple Pay automatic reload takes care of this problem very nicely. Suica would recharge anywhere because the card balance ‘trigger’ and reload process is done via Apple Pay instead of JR East transit gates and the Suica system. JR East could keep auto-charge exclusive to their VIEW cards as they do now or easily, selectively expand it. Either way they would greatly increase the usefulness of VIEW and Suica by supporting the new Apple Pay automatic reload feature. The possibilities are are pretty exciting.

Order tracking
Another very useful feature I think people will love using. The addition of QR/barcodes in the Apple Pay sheet is a first and will greatly shorten the order pickup~delivery process. The best use case of Apple Pay and bar codes that I can think of.

ID verification in apps
This is where ID in Wallet gets real. Wallet app has TSA airport checkpoint verification built-in but that’s not going to help all the government issuing agencies, not to mention software developers, around the world who want to implement digital ID verification to unlock various digital services.

JR East for example has centered their whole Super Suica MaaS Cloud initiative around ID PORT and the ability to match various region or age based services (discounts, special fares, etc.). In other words JR East and their sub-merchant or local government agency want to know where I live and how old I am. This is all provided on the Japanese government My Number digital identity card launching later this year on Android, and Apple Wallet later on. But I don’t want my personal details going everywhere. If the MaaS campaign app or website only needs to know that I live in Tokyo and am over 60, that’s the only info I want to give them. This is what the new PassKit ID request APIs in iOS 16 do: give apps only the information they need to perform a verification for a service and nothing more.

Key sharing
Nothing big here, but it does address one iOS 15 Wallet shortcoming for home, hotel keys which that could not be shared and expanded share options beyond mail and messages. I’m doubtful Apple includes office keys in the bargain but the fine print reads: available on participating car brands and access properties. We’ll find out when iOS 16 ships.

And then there’s Tap to Pay on iPhone. It’s really not an Apple Pay function to me because it turns iPhone into a very handy and portable NFC payment terminal, but it makes sense branding wise. Just say Apple Pay for making…and accepting payments. Anywhere the merchant has their payment provider POS app and a network connection, they are ready to go. This is big. Apple has lined up an impressive number payment providers in a very short time who are happy to leave all the hardware certification and secure element management to Apple and focus on software. I can practically feel the intense interest from Japan where local payment providers would love to leverage the global NFC capable iPhone for seamless EMV and FeliCa payment services. It could be an interesting Apple Pay year.

Apple Platform Security May 2022: Tap to Pay on iPhone, Express Mode scare mongers and other fun

Ahh springtime, flowers and the annual Apple Platform Security (APS) update. This year’s version has many Apple Pay housekeeping changes. Previous versions put everything Apple Pay in a single section. In keeping with Apple spinning out iOS 15 Wallet app as a separate identity, Wallet has its own separate section now, covering all the things Jennifer Bailey unveiled at WWDC21: hotel-home-office keys and ID in Wallet. The Apple Pay section adds a new category for Tap to Pay on iPhone with some interesting bits.

The Tap to Pay on iPhone servers manage the setup and provisioning of the payment kernels in the device. The servers also monitor the security of the Tap to Pay on iPhone devices in a manner compatible with to the Contactless Payments on COTS (CPoC) standard from the Payment Card Industry Security Standards Council (PCI SSC) and are PCI DSS compliant.

The Tap to Pay on iPhone server emits decryption keys to the Payment Service Provider after validation of the integrity and authenticity of the data, and after verifying that the card read was within 60 seconds of the card read on the device.

What’s interesting to me is that Tap to Pay on iPhone servers are providing a seamless payment reader experience in the same way that Apple Pay servers provide a seamless pay experience. It just works, from setup to use, the same tight integration allows payment service providers to focus on POS app development and forget about the hardware because Apple Pay takes care of everything. As Junya Suzuki tweeted recently, a lot of payment reader hardware is suddenly junk compared to what iPhone is providing with tight mobile integration and Tap to Pay servers on the backend. Now with Tap to Pay apps on the horizon, good thing that iOS 15 Wallet expanded the secure element max to 16 ain’t it?

Speaking of Wallet, this separate section covers all things “access credential” related (hotel-corporate-home-car-student ID) with App Clips suggested for provisioning multifamily home keys. Transit now includes eMoney cards (or is it e-Money, Apple seems confused about it just like Express Mode vs Express Transit) and IDs in Wallet is covered in detail. There is also an intriguing iOS 15.4 Wallet security tweak:

In iOS 15.4 or later, when a user double-clicks the side button on an iPhone with Face ID or double-clicks the Home button on an iPhone with Touch ID, their passes and access key details aren’t displayed until they authenticate to the device. Either Face ID, Touch ID, or passcode authentication is required before pass specific information including hotel booking details are displayed in Apple Wallet.

It sounds almost exactly what we already do with regular Apple Pay cards. Perhaps keys and passes only show a generic icon and checkmark with Express Mode with the double-click + authentication required for show details…it’s not very clear.

Speaking of Express Mode, ‘security experts’ are still scare mongering the masses with the tired old Russian security expert/Apple Pay VISA Express Transit exploit story that made the rounds last November, regurgitated by Forbes in the over the top scary sounding, and sloppily written (this is Forbes after all), “How hackers can drain your bank account with Apple and Samsung tap and pay apps“.

The whole security expert thing reminds me of what my uncle the doctor (who ran a medical research lab at Columbia University) used to say about his disdain for pharmaceutical companies, “They don’t want to cure you, they just want to keep ‘treating’ you with their medicines.” Human nature never changes. The gist is that EMV Express Transit Mode will always be a thorn in Apple Pay’s side because the security is up to the card companies.

The document is worth your time is you have any interest in Apple Pay and Wallet.

The Apple Pay monopoly debate part 1: context is everything

John Gruber did everyone a favor outlining some of the stakes at play in the remarkably glib, “Remarks by Executive Vice-President Vestager on the Statement of Objections sent to Apple over practices regarding Apple Pay.” The objections are annoyingly vague and refuse to specify how Apple Pay stifled competition and innovation:

(The) Digital Markets Act will…require companies designated as gatekeepers to ensure effective interoperability with hardware and software features they use themselves in their ecosystems. This includes access to NFC for mobile payments.

Today’s case addresses a conduct by Apple that has been ongoing since Apple Pay was first rolled out in 2015 <sic, 2014 actually>. This conduct may have distorted competition on the mobile wallets market in Europe. It prevented emergence of new and innovative competition that could have challenged Apple.

Mark Gurman and Jillian Deutsch at Bloomberg also did everybody a favor unmasking PayPal as one of the instigators behind the EU Commission Apple Pay investigation. Yes, that PayPal…the financial service that snuffs out user accounts whose politics they don’t like, or worse just seizes their money.

Both pieces miss important context surrounding the debate however…and with this issue context is all, especially how Apple Pay is playing out in other global markets. Most of what follows I’ve covered in earlier posts but hope to pull the various issues together in one post. Yet again, we kickoff with an updated Apple Pay diagram.

‘Open’ NFC, gatekeepers and secure element wars
Europe has been calling Apple Pay unfair since the very beginning, with many EU member banks holding out as long as they could. German banks only joined Apple Pay in December 2018 when Vestager was already actively seeking Apple Pay complaints. Less than a year later Germany passed a bill to force Apple to ‘open’ their NFC chip. Australian banks tried the same in 2017.

The so called Apple ‘NFC chip’ is not a chip at all but a hardware/software sandwich. The Apple Pay ecosystem described in iOS Security is a collection of tightly integrated polished pieces: Secure Element, Secure Enclave, NFC Controller, Wallet and Apple Pay Servers, all wrapped into a slick, easy to use UI with a final security wall of ‘secure intent’, a double-click side button hot-wired to the Secure Element. This approach has been so successful that people divide mobile payments history into pre-Apple Pay and post-Apple Pay eras.

NFC has been on Android far longer than iPhone, and ‘open NFC’ at that, but is far less successful capturing mobile payment users than Apple Pay. This is because Android device manufactures made the classic mistake of taking the ‘let’s take awesome NFC technology and figure out how we’re going to market it’ approach. Jennifer Bailey’s Apple Pay team choose the hyper focused Steve Jobs approach of starting with the customer experience and building backwards while asking: “what incredible benefits can we give the customer, where can we take the customer?” That choice made all the difference.

Apple Pay has a very simple rule: any card that loads a Java Card applet into their embedded secure element (eSE) has to reside in Wallet app. The maximum number depends on how many Java Card applets it can hold at any one time, the previous limit was 12, the iOS 15 Wallet limit is 16 cards. Developers have two ways to access iPhone NFC: 1) Core NFC framework for NFC operations that don’t use the secure element, 2) Secure Element pass certificates for NFC operations that need secure element transactions (payments, keys, ID, passes). Any developer who wants to run applets in the eSE has to apply for a PassKit NFC/Secure Element Pass Certificate. This is covered by NDA but a company called PassKit (not Apple) gives us an idea what Apple’s Secure Element Pass guidelines are:

Apple care a great deal about the user experience. Before granting NFC certificate access they will ensure that you have the necessary hardware, software and capabilities to develop or deploy an ecosystem that is going to deliver an experience consistent with their guidelines.

The end to end user experience, the whole reason behind the success of Apple Pay. But this gatekeeping is what riles banks and financial service providers who want to load their applets into the secure element without the Apple Pay gatekeeping, without the Apple Pay ecosystem and without the Apple Pay commission. They want to do their own transactions with their own app for free. This is what the EU Commission means when Vestager says: “Evidence on our file indicates that some developers did not go ahead with their plans as they were not able to to (sic) reach iPhone users.” It should read: when they were not able to reach iPhone users for free. Either the developer didn’t apply for a Secure Element Pass, didn’t pass the certification process, balked at Apple’s certification conditions, or couldn’t agree on Apple Pay commission rates.

Secure element gatekeeping is not new, it is an essential part of the secure element system:

A Secure Element (SE) is a microprocessor chip which can store sensitive data and run secure apps such as payment. It acts as a vault, protecting what’s inside the SE (applications and data) from malware attacks that are typical in the host (i.e. the device operating system). Secure Elements handle all sorts of applications that are vital to our modern digital lives…

Mobile Payments
Here, the Secure Element securely stores card/cardholder data and manages the reading of encrypted data. During a payment transaction it acts like a contactless payment card using industry standard technology to help authorize a transaction. The Secure Element could either be embedded in the phone or embedded in your SIM card.

Lifecycle management
It’s crucial that SE-embedded devices are secure throughout their lifecycle. That’s why Secure Elements need to have an end-to-end security strategy. It’s no use developing a robust security solution for a device which becomes obsolete after a period of use. This is why Secured Elements can be updated continuously to counter new threats.

What is a secure element?

Few people, especially a PayPal or EU Commission vice president, discuss the crucial secure element lifecycle management aspect. It’s not convenient for them to say the secure element ‘gatekeeper’ is responsible for keeping it secure. Far more convenient for their arguments to omit this, portray gatekeeping as unnecessary and gatekeepers as evil. In the end however, Apple has to maintain secure element updates from the various licensed secure element providers (EMV,FeliCa Networks, MIFARE, and so on) if secure payments are going to work at all This is what people who say, ‘it’s my device, we should be able to use NFC how we want,’ do not understand.

People also forget that nothing is free, you get what you pay for. With Apple Pay as gatekeeper, users get simplicity, innovation and feature updates. Simplicity: users get NFC they can use out of the box without Android-like NFC complexity such as secure element positions and obscure express mode settings.

Innovation: Apple Pay has features like Global NFC. iPhone and Apple Watch are the only smart devices that come with FeliCa built in as standard to use in Hong Kong or Japan, while Android limits functionality by market region. It’s astounding that Android, not even Google Pixel Android, has matched this basic functionality yet. We’re seeing more innovation as Ultra Wide Band (UWB) extends Wallet functionality to include ‘Touchless’ car keys and eventually, UWB enhanced automatic card selection as you approach the reader; more helpful than you might think.

Feature updates that, ‘just work’: the recent seamless Apple Cash switch from Discover to VISA, PBOC 2.0 flavored China T-Union transit cards, MIFARE Student ID, or the addition of in-app purchases and dual mode NFC for Japanese VISA card users when VISA JP finally buried the hatchet with Apple.

And the lesson? Apple Pay changed everything in the Japanese payments market, a catalyst that opened up competition and payment choices, for everybody. All boats rose together. It’s one of the most vibrant payment markets that Apple Pay operates in.

Japan is key to understanding what’s really going on in the Apple Pay monopoly debate. Japan was the first market with an established mobile payment platform in place, long before mobile EMV contactless payments took off in Europe. iPhone also has a much larger marketshare in Japan than it does in Europe. It’s a shame people pass up the opportunity to learn from the successes and failures here.

So what’s the EU Committee vision for ‘open NFC’? I think it’s a rehash of the secure element wars when carriers locked mobile payment services to SIM contracts. In 2013 Google incorporated SimplyTapp HCE (Host Card Emulation ‘secure element in the cloud’) technology as a NFC ‘workaround’ to ‘free’ NFC from the evil clutches of mobile carriers. Sound familiar? Android NFC has never been right since.

How little things change, swap ‘evil mobile carriers’ for ‘evil Apple’ and you have the same self serving ‘open’ vs ‘closed’ NFC chip nonsense that people are debating today. FeliCa Dude, the ultimate industry insider who has experienced it all, said it best: ‘It’s all eSE or nothing now.’

And yet we now have Île-de-France Mobilités (IDFM) turning back the clock, circumventing the eSE on NFC equipped Android devices and going all in with HCE for IDFM’s Smart Navigo service for Android. To me this says all you need to know what European priorities are regarding the ‘open NFC’ model: eliminate eSE gatekeepers by forcing the less secure network dependent HCE as a required option. Good luck with that. From a transit perspective, based on Mobile Suica user experiences, I don’t think HCE Smart Navigo will be a smooth ride.

The EU Committee ‘open NFC’ vision might look ideal…to Apple Pay competitors. Regular users however, will have to deal with the ugly reality of multiple NFC apps, multiple NFC secure element modes and clashing updates that cancel out NFC services. Apple Silicon eSE space is limited to 16 cards. If that sounds like a lot now, wait until you have credit cards, transit cards, home, car and office keys and ID installed along with ‘open’ NFC apps wanting their own eSE space too. Services will be squeezed out forcing the user to intervene. If the EU Committee thinks this environment fosters competition and innovation while growing mobile payment use, dream on.

Japanese tech journalist Junya Suzuki has covered NFC mobile payment developments in Europe, America and Japan for over 2 decades. He doesn’t think the EU is playing an even hand here, in his opinion Samsung and Huawei would never face the scrutiny that Apple now faces. In typical European cultural fashion, EU motives pay lip service to fair open markets while playing an underhanded game of chess to make Apple do what EU banking interests want Apple to do. In other words, a double standard.

What does Apple need to do?
I’ve always said that Apple needs to make the Secure Element Pass application process as transparent as possible. Keeping the blackbox NDA process as it is now makes Apple Pay a target, increasingly difficult to defend the status quo. Secure Element access on the level of Core NFC is a long shot, the very definition of a secure element means there has to be a developer certification process similar to EMVCo, FeliCa Networks, MIFARE, Calypso Networks Association, etc., that protects the privacy and business interests of all parties. But it would be great if there is a middle way where Apple can securely open things up for iPhone as a digital wallet, and iPhone as a payment terminal. We’ll see if Apple has anything to say about the subject at WWDC22.


Part 2: the gatekeeper difference

Recommended reading: Ruimin Yang’s wonderful overview, “Apple Pay monopoly, are we really comparing ‘Apples’ with ‘Apples?” examines the Apple Pay system architecture, how it compares to other digital wallet platforms, (Google Pay, Samsung Pay) and what ‘open vs closed’ means in the ‘Apple Pay is a monopoly’ debate.

VISA Japan and Apple still at odds over VISA Touch debit cards

Mastercard but no VISA

The April 19 launch of SBI Neobank Mastercard debit card support for Apple Pay was a bit unique: the first time that a plastic issue Japanese debit card came to Apple Pay and the first Apple Pay Japan debit card supporting the FeliCa iD payment network. Another interesting aspect is that only the Mastercard version supports Apple Pay, the VISA version is plastic only with VISA Touch (EMV contactless) support.

There are plenty of bank app issue digital only debit cards from JCB, Mizuho, MUFG and others on Apple Pay. These all work on JCB’s QUICPay (FeliCa) and J/Speedy(EMV) payment networks. Apple Pay Japan supports many different mobile payment network cards thanks to Mobile FeliCa support, by far the largest selection of Apple Pay payment networks in the world: EMV (VISA, Mastercard, AMEX, JCB), iD, QUICPay, Suica, PASMO, nanaco, WAON. But VISA issue debit cards are not supported even though there are many, not a single one on Apple Pay.

Wasn’t this taken care of by the May 2021 Apple and VISA JP agreement? For credit cards yes, one year later they are still at odds over FeliCa support in debit cards. VISA Japan brand debit cards are VISA Touch EMV contactless exclusive, single mode cards. VISA JP credit cards are dual mode EMV/FeliCa for plastic and smartphones, but not debit cards. We don’t know the reason but debit cards deifintely fit the budget customer category while credit cards come with credit checks, perks and card membership fees for upscale cards.

As an easily available budget card, VISA cuts costs by dumping the dual mode EMV/FeliCa IC chip and transaction fees for the convenience of using FeliCa iD/QUICPay payment networks. In other words VISA keeps all transaction fees for themselves while marketing the shit out of VISA Touch as the greatest thing since…whenever.

All of the other card brands in Japan have dual mode NFC as standard. Not VISA, they’re playing the long game of eliminating FeliCa payment network competition. This stupid polarizing single flavor NFC position only served to give QR Code payment networks (PayPay, Line Pay, etc.) a huge opportunity that they smartly played. End result: more payment network competition than ever before.

Apple on the other hand has a very simple rule for all Apple Pay Japanese issue cards: they must support FeliCa and all EMV cards are global NFC dual mode. Was this the price for adding FeliCa support to Apple Pay? Perhaps, I think it’s more to do with the Apple Pay vision of removing complex and confusing hardware choices, the Google Pay Japan mess, for standard ‘just works everywhere’ NFC. Has this been successful? Very...just ask Suica.

USA transit fare system evolution

Reece Martin posted an interesting video, So you built the wrong transit system, that examines the American penchant for building cheap light rail systems that don’t make long term sense. Public transit is a waste of money to Americans with money, so cheap is only way to fund and build public transit infrastructure. The problem is this cheap short term thinking costs more money in the long run. It’s a ‘one size fits all’ mentality.

But as Reece points out, systems can evolve from humble beginnings. Many private Japanese rail lines started out as street trams (that evolved from horse trams) but evolved into the heavy duty regional rail lines we have today. Fare system have evolved too, from paper, to mag strip, to IC smartcard and now mobile devices.

Transit fare systems in America suffer from the same short term cheap thinking, on full display on the MTA OMNY system, the world’s first EMV only open + closed loop fare system. When it’s completed in 2023, barring more delays, MTA will have farmed out every aspect of their fare collection and OMNY transit card issue to banks.

Not to rehash points I already made about OMNY, but Reece’s wrong transit system analogy struck a chord. And unlike rail system evolution, once the transit fare system in locked into the bank payment card infrastructure, from technology (EMV) to payment network processing (VISA, mastercard, AMEX, etc.), it will be extremely difficult, if not impossible to change anything later on.

But why is America so short sighted when it comes to public transit, never investing in a long term self-sustaining viable business model? I ran across an interesting take that explains it neatly. The USA will never have a transit platform business because public transit is a welfare and jobs program, not a self-sustaining business model:

Public transportation in the US is generally very bad and very heavily subsidized. It’s cheap because extremely little service is being run, and the government picks up most of the bill.

Public transportation in the US is less of a way normal people get around, and more of a welfare program and jobs program. Even in places where public transportation is a way normal people get around, e.g., NYC, it is run more like a jobs program than an essential public service.

Reddit user Sassywhat

Open loop fare systems are also vulnerable in new ways nobody predicted: imagine the mess if payment networks go down in a cyberwar, à la the Moscow metro when digital wallets and bank payment card networks were suddenly and omniously turned off. In the case of OMNY where, unlike Moscow metro, everything is EMV payment networked…there is no backup in-house payment settlement system, there is no plan b.

In other words not only is OMNY EMV one size fits all, it’s all or nothing.
