The Super Suica Reference

The new features that make up 2 in 1 Suica are called many things. JR East calls it ‘Next Generation Suica’ and ‘2 in 1 Region Affiliate Card’. Yanik Mangan came up with a great ‘All-in-one Suica’ moniker in his limitless possibilities podcast. I call it, and will continue to call it, Super Suica because I see wider Suica platform initiatives built off the new FeliCa OS features used for 2 in 1 • next generation Suica. It’s a looser, fuzzier platform evolution definition compared to Yanik’s tighter all-in-one card solution focused one.

That doesn’t mean that Super Suica or all-in-one Suica will ever happen they way we envision it, but at least we have some convenient handles to discuss and categorize ongoing developments until something official comes along.

This is a list of announcements, launches and posts related to Super Suica as a platform. Announcements are italic with links to JR Group PR releases, launches are bold, color classifications are as follows:

🟩🟥Next Generation Suica cards
A new card for integrating Transit IC and region cards in new ways focusing on Suica 2 in 1 Region Affiliate transit cards and FeliCa Standard SD2 • FeliCa OS as the core development. JR Cross Region Commuter Passes included as I suspect they also use SD2 Extended Overlap and represent a step towards cross region through transit for Transit IC.

🟧Mobile
The evolution of Mobile FeliCa to include UWB touchless and multiple secure element domains, Mobile Suica service expansion and re-branded assets for Mobile PASMO and Mobile ICOCA.

🟦Cloud
Cloud Suica: a cloud based fare transaction processing and MaaS Suica payment services without a reader, cloud account attached services.

Is Suica ‘all-in-one’ possible?

Now that Suica 2 in 1 Region Affiliate transit cards are out, it’s time to examine the question that Yanik Magnan posed in his limitless possibility podcast: is Suica all-in-one possible? He defines it as follows: “All-in-one in my case would mean all Transit IC and local area transit members sharing the same physical card as a common container for their data, I’m assuming (maybe incorrectly?) that Suica + PASMO on the same card would be possible through whatever totra is doing.”

In my initial Super Suica coverage I outlined all-in-one possibilities beyond the Suica 2 in 1 Region card program and called it ‘Super Suica’ to capture that idea. Unfortunately, and as Yanik points out, I forgot an important aspect: Suica and sister Transit IC cards all use the same FeliCa technology but have their own data formats. That was an oversight. Nevertheless I think we agree, so I’m retiring Super Suica in favor of Yanik’s Suica ‘all-in-one’ moniker. Here is a grab bag of various pieces that hopefully add up to an quick overview, with Suica all-in-one as a platform of technologies that others can build off of, instead of a specific transit card.

FeliCa Enhancements
Since November 2020 we’ve seen a number of FeliCa enhancements: (1) FeliCa Standard SD2, (2) Mobile FeliCa Multiple Secure Element Domains that support non-FeliCa protocols and, (3) Mobile FeliCa Ultra Wideband Touchless. The most important of these right now is SD2 because it’s a real shipping product with Extended Overlap Service and Value-Limited Purse Service. TagInfo scans of the newly released totra 2 in 1 Suica Region Affiliate transit card reveal Extended Overlap in action. The card itself shows 2 issue numbers on the back, one from JR East who own the SF (stored fare) purse and one for the region operator who own the overall card. That JR East owns the Suica 2 in 1 card SF and float is…interesting and offers a clue as to what’s going on behind the scenes.

FeliCa Standard SD2 powered totra Suica has 2 card numbers

Float Gloat
Who owns the SF purse float, how it works on the reader side and as a business model are the big issues. Here’s an example: I suspect SD2 Extended Overlap might also be used in the new Suica-TOICA-ICOCA cross region commuter passes as those cannot be issued on current plastic and require an upgrade trip to the nearest JR station. We won’t know for sure until we get a TagInfo scan of the new physical card but let’s pretend for a bit.

Say a TOICA user purchases a cross region commuter pass from Numazu (TOICA) to Odawara (Suica) for regular non-Shinkansen transit. In this case the cross region solution is easy and acceptable to all JR companies because each transit card issuer owns the SF purse, in this case JR Central. The same applies to JR East when issuing the same commute pass route for Suica. The same scenario would likely be acceptable to all Transit IC companies, sharing a common physical card as a common container for their data, but only if the SF purse ownership was clearly defined as it is in totra Suica so it works on the reader side: this is Suica SF, this is a ICOCA SF, etc., otherwise the reader doesn’t know which one to use.

In other words, let’s 2 in 1 and all-in-one for the shared resources like points, commuter passes and special discount fares for elderly and disabled users, but the SF purse is not shared for 2 in 1 or anything else. Common data format, yes. Common shared SF purse, no. At the end of the day you can’t have a Suica and a PASMO on the same card as the reader won’t know which one to use. We’ll see if Extended Overlap and Value-Limited Purse solves this wanna have cake and eat it too Transit IC dilemma. Sony is now shipping FeliCa Standard SD2 antenna module chips for the reader side of the equation so readers will be getting smarter and evolve too. That’s how I see it for Suica all-in-one, Transit IC and mobile, a gradual evolution.

Mobile hardware barriers
On the mobile front we have a smartphone hardware barrier: the Mobile PASMO Osaifu Keitai Type 1, Type 2, Type 3, mess landed on Mobile Suica with addition of multiple Mobile Suica cards on March 21. Only Osaifu Keitai Type 1 devices can handle multiple Suica and PASMO cards.

This has implications for Mobile FeliCa features such as the Japanese Government My Number Digital Card and UWB Touchless digital car keys. Mobile FeliCa 4.0 and later on Pixel devices indicate the ability to upgrade FeliCa JAVA Card applets and even Mobile FeliCa itself. Whether Android device makers will actually use this OTA ability is a mystery. To date the standard industry practice has been if you want new features, you buy a new device.

And then there is Apple. iPhone 7 JP models that support Suica do not support PASMO, UWB is only available on iPhone 11 and later, and so on. There is no guarantee that Apple will update, say iPhone 11 models, for UWB Touchless, Mobile FeliCa My Number Digital cards or even Suica 2 in 1, if and when the format comes to Mobile Suica.

We’ll see what FeliCa Dude has to say about the all-in-one subject, hopefully in a future Reddit post. It may take a while but worth the wait.

UPDATE
I’m sticking with Super Suica. Yanik’s All-in-one take is a great name focused on the 2 in 1 card architecture that fits all of Transit IC on a single card. My Super Suica take is a wider set of developing platform initiatives. Yanik’s feedback was valuable in forcing me to review my posts and define Super Suica as a platform, I thank him for it.

End of the line for Suica and the native Japan Transit IC smartcard standard?

There is a consistent theme among some Japanese tech journalists: the native Japan Transit IC smartcard system is obsolete and destined for that fabled junk heap, the Galapagos island of over-engineered irrelevant Japanese technology. The arguments always boil down to cited higher costs of maintaining the ‘over-spec’ proprietary FeliCa based inflexible transit IC architecture in face of ‘flexible, lower cost’ proprietary EMV contactless bank payment tap cards and smartphone digital wallets used for open loop transit. Is Suica really ‘over-spec’ or is it clever stealth marketing sponsorship from EMVCo members and the bank industry disguised as journalism? Logically the same argument applies to proprietary MIFARE smartcard transit systems as well but is never mentioned, presumably because it was invented in Europe instead of Japan.

Despite all the digital ink on the subject I have yet to see a single article where said costs are actually shown and compared. Smartcard deposit fees are a standard way to offset plastic issue costs and Japanese transit companies like to earn interest off the float of card deposits and unused stored value. But this is never discussed nor the fact that digital wallet issue is free of hardware costs.

Bank payment cards and smartcards have very different business models. EMVCo members and their card issuers can hide associated hardware and licensing costs in bank transaction fees that NXP, FeliCa Networks and other smartcard technology solution providers cannot. Without hard numbers we can only take journalist claims at face value, that transit smartcards are not smart at all, but expensive obstacles to lower cost open loop centralization nirvana.

I don’t buy the ‘one solution fits all’ argument and neither should you. One constant issue in our internet era is that too much centralization is not only a technology monoculture security risk, cloud services fail, and cloud centralization is abused to limit human rights. As speech is censored on SNS platforms and online profiling is used to limit freedom of travel with politically biased no fly lists, it is inevitable that face recognition transit gates will be used to track people and implement ‘no ride’ or ‘limited ride’ policies. These are issues that people must be aware of in the relentless rush towards online centralization of transit payments and services.

Nevertheless there are articles with valid criticisms well worth reading. I ran across one recently by Masanoya Sano on Nikkei that asks a good question: ‘Does taking 14 years to deliver Mobile PASMO mean the transit IC card foundation is crumbling? While I don’t agree with everything Sano san says he makes a good case that Japan Transit IC association members are failing in the face of a hydra-headed crisis: declining population with less ridership, competition from other payment services such as PayPay and EMV based VISA Touch, and ridership killing COVID lockdowns. He argues that transit companies must fix some basic problems if the Japan IC Transit standard is to survive:

  • Increase coverage: get all transit on the Transit IC card service map
  • Go mobile: for all transit cards
  • Improve the transit IC card architecture: improve compatibility and loosen up current restrictions for cross region transit, and the ¥20,000 stored fare limit

I believe most, if not all of these can be addressed with next generation FeliCa + 2 in 1 Suica (aka Super Suica) launching this year and deeper payment infrastructure sharing between transit companies. Nothing is guaranteed of course but here’s a look at each category and possible solutions.

Coverage
The transit IC coverage gap is the biggest failure of Japanese transit companies and there are big gaps. Suica only covers major population areas in Tokyo, Niigata and Sendai, roughly half of the stations on JR East are not wired for Suica. A similar situation applies to the other JR Group companies. JR East has promised to get their entire rail network on Suica with a simplified lower cost cloud based Suica in the 2020 fiscal year ending March 2021 but has yet to announce any details (they are specifically referenced in the new Suica Terms and Conditions effective March 27).

On the plus side JR West is expanding ICOCA coverage with a light rail approach of incorporating NFC readers installed in the train car for tap in/tap out for unmanned stations. No wires. SMBC and VISA use the same strategy for their VISA Touch transit boutique marketing program. It’s a practical low cost strategy for lightly traveled rural lines that reduces the hard wire requirement. Only stations that need it get wired and even those installations can use the lower cost JR East cloud based system.

JR West ICOCA area expansion includes on train NFC readers starting March 13, 2020

All major transit companies need to install these lower cost solutions to fill the transit IC gaps and integrate remaining isolated regions. VISA Touch transit boutiques are marketed as a solution for inbound and casual users, but these EMV only installation leave those transit areas off the transit IC grid for regular users and don’t work for wider area travel.

Mobile
Mobile Suica and Mobile PASMO combined represent 80% of the current transit IC card market. Mobile ICOCA (JR West) is due to launch in 2023. There is no word yet about mobile for TOICA (JR Central), manaca (Nagoya City Transit rail/bus), PiTaPa (Kansai region private rail/bus), Kitaca (JR Hokkaido), Sugoca (JR Kyushu), nimoca (Nishitestsu), Hayaken (Fukuoka City Transit). This is a big challenge but the borrowed Suica infrastructure used for Mobile PASMO is a strategy that can be applied to the other major cards.

Improving Transit IC
JR East is releasing the 2 in 1 Suica card architecture that incorporates new FeliCa OS features the most important being the “2 cards in 1” Extended Overlap Service. New regional transit card using this new FeliCa OS and Suica format are launching this month in Aomori, Iwate and Utsunomiya. The next challenge for JR East is expanding 2 in 1 Suica to existing and important region transit cards inside the JR East transit region such Niigata Kotsu Ryuto and Sendai City Transportation Bureau icsca. The JR Group has cooperated to deliver cross region commuter passes which started in

The ultimate long term success of the Japanese Transit IC systems depends on infrastructure sharing and integration. For this to happen other JR Group companies and private rail outside of the JR East regions have to incorporate the 2 in 1 Suica format and improvements for their own cards and regions. Only when all Transit IC Mutual Use Association members are using the new format can they link and combine services in new ways, and add new features such as raising the stored fare card value above the current ¥20,000 limit.

Will it be enough? I have no idea. Immediately I see problems for the Kansai region PiTaPa card association companies (Hankyu, Hanshin, Keihan, Kintetsu, Nankai) as they have to make fundamental changes to use the new card format. I don’t see a Mobile PiTaPA in its current incarnation and this is why SMBC (who run PiTaPa card accounts) and VISA are targeting the Kansai area for VISA Touch transit: non-JR Kansai transit companies have their backs against the wall and no way easy forward to mobile except for going all in with JR West Mobile ICOCA, or taking what SMBC offers them.

Open Loop competition
Kansai area private rail companies never managed to create the equivalent of PASMO. PiTaPa is a postpay card that has credit card issue checks and cannot be purchased at station kiosks like all other transit cards for casual use. Issue is limited, so Kansai transit companies issue JR West ICOCA commuter passes for people who can’t use credit cards. This is the context surrounding the SMBC VISA Touch transit for Nankai announcement that got lots of press attention as the first major test deployment of open loop on a Japan Transit IC card system.

Junya Suzuki’s latest Pay Attention installment has a deep dive on the VISA Touch Japanese open loop transit system solution powered by QUADRAC Q-CORE server technology. It is the solution also used for the Okinawa Yui Rail monorail fare system that integrates Suica/Transit IC and QR support. He argues that open loop EMV is good enough because, (1) we don’t need the over-spec FeliCa 200 millisecond (ms) transaction speed (it’s actually faster, between 100~150 ms), (2) it has a leg up on future MaaS and cloud integration. Holding onto Suica local transaction performance as ‘faster/better’ is a myth holding back progress.

I have tremendous respect for Suzuki san and his work but his arguments fall down for me here. He completely ignores the white elephant in the room: closed loop is here to stay because the open loop model cannot support all fare options. Even on the open loop systems that he champions, Oyster and Opal for example, closed loop cards are still essential and are transitioning to a closed loop EMV model for digital wallet issue. The only change is the closed loop card transition from MIFARE to EMV because bank partners are running the transit system account system backend instead of the transit company. In other words it has nothing to do with technology at all, it is bank system convenience. Bank convenience is what it all boils down to.

Making the right technology choices are essential in our era of limited resources, ride the right horse and you succeed. I want to believe the cloud holds the promise to extend transit IC to low transit volume rural areas that don’t have it now, but every time I use a slow cloud based stera payment terminal I’m reminded how impractical that approach is for stations with high transit volume.

Does it make cost sense to replace the current transit IC system and re-create it with EMV open loop when Opal, Oyster and OMNY systems will always need closed loop cards? The practical thing is leveraging a good system already in use. Upgrade the Japan Transit IC system we have now, spend precious resources that fix current limitations and extend it with new technologies like UWB Touchless.

The strength and weakness of the Japan Transit IC standard is that it’s not top down but based on mutual cooperation. It’s not one entity but association members have to move forward as if they are one. JR East has been the technology leader and is working to improve and share it at lower cost. 2021 is not the make or break year for Japan Transit IC, but it will be an important and challenging one that will set its future direction.

The good old Japan Transit IC card mutual use map, all the little one way arrows marked with the ‘IC’ logo pointing outside the main IC area indicate transit system compatibility.

ICOCA Widens Transit Footprint

One glaring weakness of the Japan Transit IC system is that it’s not universal even on the very rail networks that built the system. Suica for example is mostly absent in stations outside of Tokyo, Niigata and Sendai metro regions, roughly half of JR East stations. It comes down to cost: hard wiring every station is expensive. This cost problem is one that JR East plans to address by rolling out a cloud based low cost ‘simple Suica’ for all stations. They already missed a 2020 deadline and need to deliver on their promise if Suica is remain a viable payments competitor in the hyper competitive Japanese market.

JR West meanwhile is busy expanding ICOCA coverage on the their rail network with Fukuchiyama and Kisei line additions going online March 13, 2021. JR West also added ICOCA connecting commuter passes for Osaka Metro in December, the kind of arrangement that Suica and PASMO have had in place for years. It makes sense for JR West to expand now in preparation for the Mobile ICOCA launch in 2023.

The Kisei line is somewhat unique in that smaller stations are unmanned and local trains are one man operations with passengers getting off at the front for ticket verification. ICOCA readers are located at car exit points, passengers tap out similar to using a bus. This kind of operation would fit well on similar ‘one man’ operations like the JR Central Minobu line which are still limited to paper tickets.

Road to Super Suica: mobile expansion

The JR West Osaka Expo 2025 transit vision incorporates Mobile ICOCA and MaaS services

The October 21 announcement from JR East-Hachinohe City-Northern Iwate Transportation is the 3rd Super Suica local transit card and follows earlier Super Suica local transit card announcements for Utsunomiya Light Rail and Iwate Transit Co. Ltd. These fit neatly into the narrow definition of Super Suica as a local area ‘2 in 1’ transit card within the JR East region that hosts different transit company commute plans and reward points on a single card. New FeliCa chips announced in September have new features like ‘Extended Overlap Service’ to support the ‘2 in 1’ model.

The real test of Super Suica is the wider definition beyond the 2 in 1 Suica Region Affiliate Transit Card program and how it plays out both JR Group companies and non-JR transit companies outside of the JR East (JRE) region. The more JR East shares Mobile Suica cloud assets, the more all transit companies can eliminate duplication and save costs. In the COVID era of constrained public travel, reducing costs while maintaining good service is more important than ever.

On the mobile front it’s clear that Mobile PASMO was an unannounced joint effort between JR East and PASMO Association. Mobile PASMO service and software is Mobile Suica dressed up in PASMO colors, the penguin character swapped out for a robot. The JR West announcement of Mobile ICOCA one week after the Apple Pay PASMO launch is no coincidence. The Super Suica mobile template is in place and road tested, PASMO and ICOCOA are the first 2 customers.

Who’s next? Junya Suzuki pointed out that Suica and PASMO together account for 80% of Japanese transit card issue, ICOCA added in makes that 90%. The next largest market and logical choice is manaca, the Nagoya area equivalent of PASMO. Forget about the Kansai area PiTaPa, the credit card as transit card concept was a bust and will likely never go mobile unless it’s repositioned as just a credit card. JR Central’s TOICA has deep pockets, and it’s said that TOICA runs on Suica servers, but JR Central has a sibling rivalry thing with JRE that might get in the way.

From a market share perspective manaca be the next logical mobile service candidate with the Kyushu area transit cards (SUGOCA and nimoca) following soon after. The next development to keep an eye on is the ‘2 in 1’ Super Suica local transit card model and if other major JR Group members offer a rebranded version of it in their respective transit regions.

From a western perspective people wonder ‘why not just have one national transit card and be done with all this nonsense’. A national transit card has been discussed by various Japanese governments from time to time, and gone nowhere. The shared infrastructure Super Suica model that aims to lift all boats certainly plays more to the traditional Japanese business mindset. In these challenging times that can be a good thing.
