Hacker News and Reddit have very different user audiences but each have their share of ‘my experience is the world’ navel gazers. This is a plus: the comments are fascinating to read. The Andreessen Horowitz site posted a piece by Avery Segal, Remember QR Codes? They’re More Powerful Than You Think. Somebody posted it to Hacker and somebody else posted a link to my Transit Gate Evolution piece in the comments. I think it’s hilarious and insightful that somebody can look at the same QR code transit video in the piece and write, “The QR code video shows a ton of people going through the turnstiles quite fast.” A ton? Fast? I guess the commentator never experienced rush hour Shinjuku station gates.
Segal’s piece is a simple Mainland China travelog highlighting all the things people can do with a WeChat/Alipay account and WeChat Pay/Alipay integrated QR Code smartphone apps there. There is very little analysis and the opening paragraph reads more like PR, which it probably is. After all, Andreessen Horowitz is a venture capital firm though I can’t figure out if Segal is trying to sell WeChat/Alipay or QR.
Companies in the US have been slow to adopt QR codes, but those who dismiss them as having “been around forever but never taken off” underestimate their wide-ranging potential. Camera-based solutions like QR codes (or facial recognition, for that matter) can make traditionally clunky user experiences seamless and intuitive. QR codes connect our online identity to the offline world, allowing users to essentially log in to physical locations—and bring their data with them. This delivers a number of benefits: brands learn user preferences, while customers gain a more tailored and social experience, as well as perks like automatic loyalty programs built into every transaction.
The Hacker News crowd discusses the pros and cons of QR vs NFC, but I think that they along with Segal completely miss the point: it’s not the technology, it’s the service layers built on top of it and how well they integrate that really matters. Actually it’s the only thing that matters.
The Suica example. FeliCa is great NFC technology but nothing great by itself: the Suica card format built with FeliCa, the nationwide Transit IC card inter-compatibility built around the Suica card format, the Transit IC eMoney standard built on top of that, Mobile Suica, Apple Pay…each new service layer builds on the previous layers and adds value to the whole. The value is the quality of integration, a sum greater than the total of parts.
China is a very different country and transit infrastructure isn’t a business. I’m sure that Alipay and WeChat Pay were allowed on host their QR code services on ‘public infrastructure’ because it also benefits the Chinese Communist Party in some way and helps the CCP steer society where it thinks it should go.
There is another important aspect that Segal and the Hacker crowd fail to see or discuss: central processing vs. local processing. The whole point of Transit Gate Evolution was explaining the Apple Pay Suica secret: a great local processing front-end (FeliCa/NFC-F/Suica) integrated with a great central processing back-end (Mobile Suica + Apple Pay EMV credit/debit cards). Segal assumes that central processing is everything and that the internet, mobile networks and cloud services are always going to work everywhere 100% of the time. They don’t.
Some people look at Japan and see a crazy mess of cashless payment options: credit cards, iD, QUICPay, Suica, QR Code players like PayPay and Line Pay, all vying for customer wallet space. ‘It’s a shame,’ they say, ‘In our country we have it all worked out with EMV contactless bank cards that do everything.’
I’ve got news for those people, the mess they are seeing in Japan is the future, it just hasn’t come to their country yet. It’s the revolution of payments on smartphones that started with digital wallets like Apple Pay, Google Pay, etc. but it’s sure not ending there, the number of payment options is only going to grow. Get used to it.
The one size fits all thinking of the plastic card era is dead. Some people think it still lives on in digital wallets, but it’s dead. The future belongs to nimble players who mix and match the best payment technologies for the job at hand and offer customers better services along with it.
The so called ‘FeliCa failure’ curse is actually a kind of blessing: the market payment technology fragmentation gave new players a footing to try different payment methods. Diversity isn’t a weakness, it’s a strength. The diversity of Japanese cashless payment options is the result of its longer history of mobile payments.
That is what smart devices, digital wallets and payment apps do: they erode the old ways and bring fragmentation along with new opportunities. There will be cycles of expansion and consolidation but one size fits all will never come back. Call it cutting edge or call it stupid, like it or not, the cashless mess is coming your way.
while QR codes have proven remarkably effective at meeting most people’s mobile payment needs, it seems ill-suited for public transit compared with NFC. Since NFC relies on radio waves, payment requires only a tap of the phone. There’s no need to wake it up or turn the screen on, making it as convenient as traditional transit cards.
The limitations of the <QR> technology are apparent even as cities race to install QR code scanners in turnstiles across the country. Over time, though, the inconvenience might be enough to nudge China away from its reliance on QR codes.
The long answer requires a quick look at transit gate technology evolution. The success of Suica can be found in its development process, a fascinating story by itself. The Suica card and transit gate were developed as one thing to replicate the ease of flashing a commuter pass to the gate attendant without stopping.
A video of old style paper ticket manned gates illustrates the start point. There is no physical barrier. People slow down to get their ticket punched but rarely stop. For a commuter pass the user flashed a wallet with a clear plastic window at the attendant and kept on going, shown at the 0:16 mark:
Shigeo Miki came up with an idea of using IC cards for tickets. The magnetic-type ticket automatic gates, which were in use since the 1980’s, had some inconvenient aspects. Old-style passes could be shown to attendants without being taken out of their cases. But to use automatic ticket gates, passengers had to take them out, pass them through the automatic gate, and then put them away again. He thought that was a decline in service quality…
This was the late 1980’s when IC cards were just coming into wider use, but not for transit. The Suica project had a large impact on Sony FeliCa development as did the Hong Kong Octopus project starting in 1992…
Furthermore, systems that read ID data from read-only cards and interact with the main computer each time someone goes through the ticket gate could not keep up with the enormous volume of data processing transactions in rush hour. So Miki and his fellow researchers perceived that the cards must be read/write types.
There we have it, the Suica project goals were: open gates, waving commuter passes, local processing. Magnetic strip paper ticket gates got faster, Omron states the speed is within 600 Milliseconds (MS), and better with the ability to handle and sort multiple tickets at a time. Suica is cool but nothing is cooler than watching the physical action of a well designed machine:
Despite development problems and a low research priority within JR East at the time, Suica success was achieved by moving the battery supply from the card to the gate and creating fast reliable performance with an illuminated target NFC ‘hit area’ tilted forward at 15 degrees, the same design you see today on the JREM EG-20 transit gate. The EG-20 already looks surprisingly similar to the open public transport gate concept. (Here’s a Japanese website that catalogs every JR East ticket device if you are interested)
Smartcard Transit Gates Compared Smart transit cards were an important development that revolutionized transit and launched successful systems such as Suica, Hong Kong MTR Octopus and TfL Oyster. However all smart transit gates are not equal. Compare the Malaysia Touch n’ Go gate speed with Suica on EG-20:
One of the commentators notes the crucial differences: FeliCa (used for Suica and Octopus) is the most efficient NFC protocol, 212 kbps minimum/847 kbps maximum, while Touch ‘n Go is mainly MIFARE Classic at 106 kbps an “early form of ISO 14443A, …the least efficient NFC protocol.”
There is another crucial difference: Japan transit gates are open by default and close only when needed, just like the old manned JR gates, while Malaysia and Hong Kong gates are closed on default or use old fashioned turnstiles. The combination of the Ferrari fast FeliCa combined with the well designed JREM EG-20 gate (and variants) that is default open, keeps people moving, best highlighted in a Pokemon Go event ‘Pikachu’ transit gate video:
Suica speed is part of what makes it fun but there is a serious reason behind it: major Japanese transit operators like JR East have to move a tremendous volume of people through a fixed station infrastructure space that cannot be enlarged. Bigger stations with more transit gates are not an option. So the system focus is using the fixed space infrastructure as efficiently as possible. That is why the Suica transaction speed is less than 200 MS, that is why a Suica transit gate must clear 60 people a minute.
Open Loop Multiple Protocol Transit Gates Compared Using EMV contactless with cards and smartphones, or QR Codes on smartphones for transit instead of native transit smartcards, is a step backwards from the fast read/write local processing model of Suica, and back towards read only centralized processing, one of the original system bottlenecks that Suica was designed to avoid. The QR Codes used for transit in China appear to be particularly slow and a poor match for high traffic stations. Poor gate design is certainly a factor here.
EMV has its own transit gate problems as well, as Singapore transit users found out in the recent rollout of EMV SimplyGo service there, things slow down:
It’s fascinating that Singapore’s Land Transport Authority (LTA) dumped the fast FeliCa (rated 200 millisecond transaction but Octopus clocks in at around 100ms) behind EZ-Link cards to roll their own faster CEPAS technology (rated 180ms transaction) but are now letting super slow EMV contactless (500ms plus and counting) on their transit reader infrastructure. It’s like ripping out all the cutting edge transit gate technology and replacing it with clunky old supermarket cash register technology.
The last comment in the first Twitter timeline is an important observation: most EMV transit is simply grafted onto the current transit gate infrastructure which was designed for something else, a factor contributing to unreliable performance, forcing users to adapt. Most of the multi-protocol transit gates in service are poor design. Central processing EMV supermarket checkout technology was never designed with transit in mind, so we get poorly designed technology bolted on poorly designed transit gates.
This leads to another EMV issue users have to adapt to: ‘card clash’. When EMV is bolted onto an existing system slapping a wallet on the transit reader doesn’t work anymore, the card has to come out of the wallet. This is still one of the nice things about plastic Suica cards. Young Japanese women in particular seem to enjoy slapping those cute little Hello Kitty wallets on the gate reader with a surprisingly hard thwack, stress relief perhaps? Chicago Ventra support offers insight on the current state of EMV transit:
Get your device ready, first, for fastest entry
“Card clash”: touch only your desired payment method
Multiple credit cards: always use the same card on the same device on transit readers
These are issues that Apple Pay EMV Express Transit is designed to fix by designating a single EMV bank card for transit but it cannot change the inherently slow EMV transaction speed or solve the limitations of EMV bank card architecture which is basically centrally processed read only. There are limits on how much the central processing read only model can achieve when fast, precise, local transactions are required. All EMV Express Transit does it designate a bank card that tells the transit gate reader: I am a real bank card, not a forged one, we’ll settle the bill later.
The Abacus article points out the slow uptake of NFC, blaming it on UnionPay, but it boils down to the PBOC flavored EMV spec itself:
Each card organization has formed its own specifications based on the EMV specification based on its own business refinement and expansion, such as China UnionPay’s PBOC 2.0 specification, VISA’s VSDC specification and MasterCard’s M/Chip specification. Each specification follows the EMV specification for basic transaction processes and security mechanisms, but differs in terms of data element definition and extended application…PBOC based on the EMV standard, combined with the needs of domestic banks, the People’s Bank of China promulgated the PBOC series of standards: 1 PBOC1.0: e-wallet / electronic passbook / magnetic stripe card function 2 PBOC 2.0: E-wallet extension application, debit/credit application, personalization guide, contactless IC card standard 3 PBOC 3.0: Cancel e-wallet and electronic passbook application, cancel downgrade transaction, multi-algorithm extension, multi-application extension, mobile payment standard
Beijing and Shanghai Transit cards were originally MIFARE but instead of examining what technologies would be best for next generation transit needs, China simply migrated them to the much slower PBOC 2.0/EMV specification implemented on the China T-union transit card architecture. The China T-union card is country wide transit prepaid card spec for interoperable transit cards that can work everywhere, similar to what Japan has with Suica, ICOCA, PASMO, etc.
Unfortunately, instead of letting transit cards be transit cards, China Union Bank demanded the transit card be a slightly different credit card. The EMV transit problem all over again. The rollout of new format card issuance has also been slow and piecemeal.
Chinese users familiar with Suica performance find China T-union cards slower and less reliable at the gate, no surprise there. Because PBOC is slow EMV NFC spec 500 MS transaction speed and tightly chained to UnionPay, the transit gate performance edge is not great enough to ween users away from QR Codes and the point benefits of sticking with AliPay and WeChat Pay.
If the performance gain was similar to the huge Suica over QR difference, coupled with an open flexible backend for using different payment methods to add money, China T-union would stand a better chance of nudging QR users to NFC for transit. As it stands now, there’s no real difference between a UnionPay card and a China T-union card at the transit gate. One is post pay, the other is prepaid, 2 versions of the same thing, marginally faster than QR, but not much.
Whatever the causes for the current situation, it’s a perfect gift to Chinese QR code players, I suspect that the arrangement is also a profitable one for the Chinese government on some level because if it was not, they wouldn’t be adding QR Code readers to transit gates.
QR Codes for Japan Transit Some Japanese tech journalists have fretted about JR East not embracing QR Codes on transit gates because JR Central plans to completely eliminate paper tickets for the next generation Chuo Shinkansen. It’s less about QR and more about eliminating magnetic strip paper tickets. JR East does have limited QR code use for ticket purchases at station kiosks, we’ll likely see wide support of many cashless payment options, QR included, with the new JR East eTicketing system due in April 2020.
QR Codes have seen some limited use on local monorail systems such as Okinawa’s Yui Rail but Suica compatilbilty is coming to the system in April 2020. The next generation Super Suica that does a lot more for much less, will arrive in April 2021. QR Codes for transit use in Japan will reamain a small side show far away from the main attraction.
In summary, the use of EMV bank cards and QR Codes for transit all comes down to transit company priorities for safe operation, better customer service and long term business goals. My position has been and continues to be is that it’s a better long term business opportunity for transit companies to:
Offer robust support of bank cards, QR and digital wallets on the backend for adding money to native transit cards on digital wallets and plastic, where they are really useful and add value without giving control away to outside companies.
It’s a simple choice really, moving people quickly and safely by transit, managed wisely, is a license to make money. A company can either use that license to build something of greater long term value for the users and businesses of the transit region, a win-win, or give it away to someone else.
The UK media has a thing about Japan. Japan must always be portrayed as ‘pathetic’. Pathetic losers, pathetically isolated, pathetically out of step, arrogant, etc. Does this make UK readers feel better about themselves? I don’t know, but I have learned to take any UK media coverage of Japan with a large dose of skepticism, laugh at it, or do what the Japanese do: ignore it all together. After all, who cares what UK journalists think about Japan when they cannot be bothered to spend the time and effort to find out what’s really going on, and actually report it.
Case in point, today’s Financial Times piece: The painful path of curing Japan of its cash addiction (paywalled). It has all the nasty lazy hallmarks of UK style Japan reportage: the ‘Galapagos trap’ (Japanese isolated from the rest of the world), the ‘FeliCa failure’ (FeliCa has stunted the spread of cashless systems that have taken hold elsewhere in the world, i.e. EMV is king of the world and Japan is isolated), and now the ‘QR code failure’ (Japan was slower than China applying OR codes for mobile payments, isolated and out of step again).
This last failure, of course, leads into the recent 7-Eleven QR Code 7pay launch and security meltdown, and the narrative that FT really wants to sell here: the grand parable of modern Japan, a nation of has-beens:
the (7pay) incident has become part of a grand parable of modern Japan: a country in a permanent tension between its high-tech image and the realities of aging consumers and squandered opportunities.
WTF? I thought we were talking about contactless payment trends in Japan here, not the UK take of the world order. Why is the management failure of one company the only narrative that matters despite the many successes and changes happening right now? FT’s pathetic Japan narrative, is pathetic.
As any Japanese IT journalist will tell you, analyzing real Japanese contactless payments market trends is very difficult because the beast is highly regional. What you find in Tokyo is completely different from Fukuoka, or rural areas. You have to look at many different pieces to understand the trends and where they are going.
The best thing FT can offer is a 6,000 person web survey from MyVoice which does not include any crucial context, which in Japan is everything. What regions are we talking about here, what’s the age spread, the amount of use, average purchase amounts, etc. There are tons of little web surveys but they don’t convey the big picture. Sure, lots of people might use PayPay to buy this weeks discount gum or get the startup campaign goodies, but that has nothing to do real day to day contactless payments use.
The rest of the piece is padded out with phoned in quotes from the usual suspects: ‘financial analyst experts’ from Credit Suisse and Mizuho Financial Group, the latter of which have skin in the game with their own QR Code payment system.
All in all it’s the low easy road that big established media takes too often these days. The Financial Times had a great opportunity to explain the exciting changes happening in the Japan payments market right now, and open a lot of eyes and minds. Unfortunately they blew it. That’s a loss for everybody, especially FT.
I think we are witnessing the QR Code tipping point in Japan. After yesterday’s 7pay ‘latest in a series of QR Code payment system security meltdowns’, IT journalist Tsutsumu Ishikawa tweeted, “It’s time to promote FeliCa for Japanese cashless.” Ishikawa san also retweeted Twitter user S: “QR is so over,” who goes on to say that the low bar QR Code entry point only resulted in incompetent players setting up payments systems. The resulting mess and confusion ends up destroying the very cashless migration momentum the industry worked hard to create.
