State of Suica 2022

Now that the 1st wave of Suica 2 in 1 card launches is complete, it’s a good time to review the ‘State of Suica’. And it’s always interesting to examine the cultural differences too, when it comes to labeling trends as ‘good’ or ‘bad’. Westerners for example invariably say, what’s the point of having so many Suica card flavors? It’s a waste, better to have just one. It’s a classic double standard professing to want but insisting that life should revolve around single kind of credit card. Japanese don’t seem to care much as the culture is adept at ‘振り分け’: this thing for doing this, that thing for doing that. And the region affiliate users getting Suica for the first time seem pretty excited and all Suica varieties work the same for transit and e-Money purchases.

As of now we have the following plastic Suica card flavors beside the regular Suica available at station kiosks: Rinkai Suica, Monorail Suica, Welcome Suica and Suica Light. On the Mobile Suica side we have: Osaifu Keitai, Apple Pay, Google Pay, Fitbit Pay and Garmin Pay, along with branded Mobile Suica for Rakuten Suica and au Suica on Osaifu Keitai and Mizuho Suica on iOS. Last but not least we have 11 new Suica 2 in 1 Region Affiliate Transit cards that are the keystone of JR East’s MaaS strategy.

What exactly are the differences? It comes down to commuter passes or points. For Suica 2 in 1 cards specifically, it is both. This is a small but very important difference. All the other non-regular Suica outside 2 in 1, come with specific features and limitations. Rakuten and KDDI au users can recharge those Suica with those outside point systems but they can’t add commute plans. Welcome Suica expires in 28 days, Rinkai and Monorail Suica exist for commuter passes and nothing else, and so on.

Suica 2 in 1 doesn’t have limitations and does more than any other Suica: it can hold 2 different commuter passes (one from JR East, one from the region affiliate) and it supports 2 different point systems: messy JRE POINT which is an optional account setup manually linked to the Suica card number, and local government subsidized region affiliate transit points which are automatic and stored on the card itself. The only thing the user needs to do is use the appropriate card for transit to earn and use transit point discounts.

In a mobile payment era where everybody is distinguishing themselves with increasingly complex reward point schemes, the simplicity and flexibility of Suica 2 in 1 transit points, think of it as locally processed transit point stored fare, can go places that old Suica cannot. Imagine how many more people would use Suica transit in Tokyo if it came with transit point discounts. There are other 2 in 1 features not yet supported by regular Suica: disabled and elderly transit user discounts. These are coming to Tokyo area plastic issue Suica, and PASMO too, this October though I suspect those won’t come to Mobile Suica until it gets an upgrade.

Mobile FeliCa hasn’t been updated to the next generation ‘Super Suica’ FeliCa SD2 architecture yet, but once updated we should see Suica 2 in 1 on mobile and new Suica features, along with more Suica 2 in 1 Region Affiliate cards. All in all the new Suica 2 in 1 card format tells us where JR East wants to go.

There are some interesting numbers from the JR East FY results. All things transit took a huge hit in FY 2021 from the COVID pandemic, Suica included, but are now recovering though still below pre-covid transaction levels. Another surprise is the popularity of Eki-Net eTickets, a 39% usage rate is not bad for a service that only started in March 2020. One of the smarter things JR East did with Eki-Net eTicket discounts is making them simple and available to all Eki-Net users and credit cards. The JR Central EX system has 2 different Shinkansen eTicket tiers (EX-Press and smartEX) with larger EX discounts limited to select credit cards.

There are lots of things that JR East needs to do longterm, more Suica day passes, Mobile Suica recharge that is available 24/7, phasing out legacy mag strip ticketing and UWB touchless transit gates. In the short term we have Cloud Suica and Mobile ICOCA coming online in March 2023, the end of the current fiscal year. At the very least it should be an interesting time for JR West ICOCA users, and one more nail in the PiTaPa coffin.


Super Suica Cloud

A Japanese friend once told me that when Suica first came out, young people in Tokyo sent Suica cards to hometown families to use for coming to Tokyo. But parents and grandparents sent them back saying, “we can’t use them,” even when they could use them in their local area.

What they were really saying was, ‘Suica doesn’t get us the same transit perks we do using local paper tickets or mag stripe cards.’ There has long been a huge gap between transit services available in major cities which ‘don’t work’ in one way or another for those in outlying areas.

That’s the challenge facing the Japanese transit IC card system. Being able to use a Suica or ICOCA transit card in the sticks isn’t enough, local region services must be attached to make it worthwhile for people living outside major city areas. Transit IC has to evolve if it is going to be useful in the mobile era with proliferating smartphone payment apps vying for a piece of the national transit pie.

Now that we have a clearer vision of how Suica 2 in 1 Region Affiliate cards address this problem and how they are central to JR East’s MaaS strategy, it’s time to look at evolving JR East cloud services and how they fit into that strategy. There are a number of new cloud service parts that have come on line over the past year, or are coming soon…some visible, some not.

Taken together they comprise what I call ‘Super Suica Cloud’ following my earlier definition of Super Suica: a collection of mobile focused transit and payment infrastructure services that can be shared with or incorporate other company services, or be hosted by JR East for other companies. MaaS is an elastic term that holds a lot of flashy concepts, but I think JR East is aiming for something more low-key but practical, a Japanese Multimodal MaaS if you will.

The immediate concrete end-goals are service expansion with cost reduction; elimination of duplicate or proprietary dedicated infrastructure in favor of open internet cloud technology. With that in place the next goal is tight integration of transit payment services that work everywhere but also deliver tailored services for local regions. Let’s examine the parts.

Mobile Suica
People assume that Mobile Suica does everything mobile, but basically it’s a station kiosk in the sky. Put money in for a transit card, put money in for a recharge, or a commuter pass, a day pass, and so on. Issuing, recharging and managing Suica cards on mobile devices is what Mobile Suica was built for.

As the world’s first mobile transit card service, Mobile Suica has made a lot of progress over the years expanding support to include Android, Apple Pay and wearables, but the work isn’t done until any mobile device from anywhere can add Suica. And since Mobile Suica hosts Mobile PASMO (launched in 2021) and almost certainly the forthcoming Mobile ICOCA (coming early 2023), getting those on an equally wide digital wallet footing is just as important.

As the face of all things Suica on mobile devices, the smartphone app could have many more things plugging into it, like Hong Kong’s Octopus App. So far however, JR East has chosen, wisely in my opinion, to keep it limited to basic housekeeping, breaking out ticketing and MaaS functions to separate apps.

Suica Fare Processing • JESCA Cloud
This is the traditional Suica network system centerpiece that locally processes touch transit stored fare on station gates and touch e-Money payments in stores. The station gate fare side is getting a major new addition in 2023 with a simplified cloud based Suica transit fare network rolling out to 44 Tohoku area JR East stations. This new Cloud Suica area closely aligns with Suica 2 in 1 Region Affiliate cards launching this year.

Cloud Suica 2023 additions (Orange) and Suica 2 in 1 cards below

The store payment side also has a simplified cloud based FeliCa payment network and a name: JESCA-Cloud. System details are vague but Cloud Suica transit fare and JESCA Cloud store payments appear to do the same thing: move transaction processing off local hardware and onto the cloud. Fast processing time is very important at transit gates, Suica tap times are the fastest out there. Those familiar with the Suica system say Cloud Suica will spilt it 50% local processing / 50% cloud processing. Dumber terminals, smarter cloud that still offers great Suica service…we hope.

One difference Cloud Suica has from a similar effort by JR West for ICOCA, is that Cloud Suica supports all the standard Suica features like commuter passes that cloud ICOCA does not. An interesting side note is that JR East hosts the processing for JR Central’s TOICA transit card network, they can certainly put the new Cloud Suica backend to good use expanding TOICA coverage in rural lines like the Minobu line.

ID Port
Comb through recent JR East press releases and you’ll find 3 service announcements built around ID PORT, a “cloud based ID verification solution” from JREM (JR EAST MECHATRONICS CO., LTD), the company that builds Suica infrastructure.

  • Maebashi City TOPIC MaaS service (November 2020): Local MaaS discount services provided by TOPIC that use Suica with My Number card address and age to verify eligibility:
Maebashi City TOPIC MaaS service links Suica and My Number Card to unlock services
(Japanese Railway Engineering January 2022, No.215)
  • Suica Smart-Lock (December 2021): registered Suica card access a variety of access services provided by ALLIGATE:
CyclunePedia bike parking

All of the announcements have 3 components: JR East (Suica), JREM (ID-PORT), 3rd party services attached to Suica using ID-PORT as the system glue. Most of these are either in testing or ‘coming soon’. What is ID-PORT?

ID-PORT is explained on the JREM site, but the first public mention in an NTT Data PDF document from November 2020 is more revealing: “The Open MaaS Platform and supporting Multimodal MaaS”. The JR East Suica MaaS strategy is outlined with various scenarios that indicate ID-PORT is the JREM side with MaaS services on the NTT Data side. In other words a co-venture.

NTT Data Journal: A multi-model open MaaS platform

The job of ID-PORT is that it acts as the middle man ID verification glue linking a registered Suica (or similar Transit IC card) with various 3rd party services such as special ticketing, access and discounts.

The interesting thing about the ID-PORT and NTT Data MaaS platform reveal is that the timing exactly coincides with Sony’s release of FeliCa Standard SD2, the next generation FeliCa architecture used for Suica 2 in 1 cards. One of the little discussed new SD2 features is ‘FeliCa Secure ID’. Here is Sony’s diagram of how it works.

Sony FeliCa Standard SD2 FeliCa Secure ID

Look familiar? Yep, ID-PORT sure looks like FeliCa Secure ID in action. The JREM ID-PORT page is more rounded out, incorporating non-FeliCa ID verification methods like QR and bio-authentication and many different services. ID-PORT has already been added to JESCA-Cloud and CardNet so that linked services are widely available on store payment terminals, not just Suica transit gates. In sum it represents MaaS and Account Based Ticketing in action with ID-PORT at the center.

JREM ID-PORT

MaaS and Account Based Ticketing in action
MaaS and Account Based Ticketing are the new hotness now that people realize open-loop doesn’t solve everything as banks and card companies want us to believe. Fare Payments Platform provider Masabi explains it this way:

Account Based Ticketing (ABT) shifts the fare collection system from being ‘card centric’, meaning the ticket holds the journey information and right to travel, and moves this to the back office. Moving the ticket information to the back office holds a number of benefits. It means passengers no longer need to buy a ticket or understand fares to travel and instead they use a secure token, typically either a contactless bank card, mobile phone or smartcard.

In this scenario FeliCa Secure ID is a secure token, ID-PORT is the secure token platform using the secure token to link ticketing and services together. That sounds nice but when will we see it in action? I think we already are.

Eki-Net 2 Account Based Ticketing
As explained above, ABT attaches tickets from the cloud to a secure token, in this case Suica. By this definition Eki-Net 2 Shinkansen eTickets represent JR East’s first step into ABT ticketing. Eki-Net uses registered accounts and credit cards purchase and attach eTickets to Suica. These eTickets do not use Suica prepaid stored fare nor is any eTicket information written to the Suica card, the eTicket system uses Suica as a secure token. JR Central smart EX is a similar ABT service and let’s not forget the web-only multi-lingual JR-East Train Reservation service that provides some ABT ticketing for inbound visitors.

Will JR East ABT implement the ‘no longer need to buy a ticket’ part of the Masabi ABT vision? I doubt it. Shinkansen eTickets are much lower ABT hurdle: lower passenger volume on far fewer transit gates than regular Suica gates. The complexity of interlocking non-Shinkansen Japanese transit systems and the vast array of fare schedules, such as higher paper fares vs cheaper IC fares, don’t easily straitjacket into an open-loop or ABT fare box, and it doesn’t fit the JR East business model.

Suica 2 in 1 region extras
There are services besides ticketing attached to a ‘secure token’ Suica. One of the important things easy to miss in the Suica 2 in 1 rollout are extra region features not available in regular Suica. Disability Suica cards for example. These are finally due to launch on Suica and PASMO cards in October 2022, but disability Suica 2 in 1 cards are already available in region affiliates.

There are also region affiliate transit points, one of the services that ID-PORT is advertising for JR East MaaS. Transit points all ‘just work’ automatically the same way. Points are earned from recharge and transit use and automatically used as transit fare. The user doesn’t do anything except tap the bus card reader. No registration, no setup. I wish JRE POINT had an option to work this way.

Transit points mimic the scheme of old regional transit mag strip card like Nishitetsu that gave ¥1,100 with a ¥1,000 recharge. Those features were popular (automatic simplicity in action again). PayPay used a similar strategy to quickly build a large customer base but pissed everybody off later as they got big and started changing bonus rate returns like used underwear. That won’t happen with Suica 2 in 1 cards as region transit points are locked in by local government subsidies to the region affiliates.

Streamlined simplicity, integration, regionality
Despite the la-la-land promise of MaaS and Account Based Ticketing, the ‘just works’ angle is crucial for people to actually use it. One of the current problems with Mobile Suica, Eki-Net, JRE POINT and the MaaS services JR East advertises is that is each service is a separate app + registration + attach cards process. This needs to be streamlined into a single simple JR East sign-on service option like Sign in with Apple that works across multiple services. I suspect ID-PORT is the glue between Mobile Suica and JRE POINT that keeps those registered services automatically linked even if the Suica ID number changes. A good sign because the JR East cloud needs a lot dynamic linking.

There is also the larger problem of integration outside of JR East, such as the current state of multiple online ticketing services; Eki-Net for JR East, EX for JR Central, Odekake-net for JR West, and so on. It would bet great to have a common app that plugs into every online ticketing service. At the very least JR Group companies need to integrate eTicketing the same way they have always integrated paper ticketing for one stop service in their own apps.

The bigger question is do Super Suica Cloud parts (ID-PORT / Mobile Suica / Cloud Suica) scale beyond JR East to include other JR Group companies (JR West, JR Central, etc.) and potential region affiliates nationwide? If increased services with reduced costs is their MaaS goal, JR East needs to step up to the plate and share. Infrastructure sharing with backend integration is the only way forward for all. Japanese transit has always excelled at physical interconnection, the cloud service side needs the same level of interconnectedness.

There are cultural angles too. Japanese have a passion for hunting down local perks, bargains and discounts. People complain about Eki-Net (deservedly) but they sure scramble and swamp the system getting those time limited discount eTickets like crazy pre-COVID era Black Friday midnight Christmas shopper crowds rushing into the store.

There is also the traditional cultural value of promoting local economies. As the saying goes, cities are only healthy in the long term when local economies are healthy too. If JR East is really serious about promoting regional MaaS, they’ve got to aggressively offer linked services that clearly promote regions. There are many region programs that visitors are simply not aware of. JR East can do a lot simply linking them to discount coupons, limited offer eTickets and such that appeal to the bargain hunter Japanese mind. The key is being creative and nimble like QR payment players.

The JR East MaaS region affiliate strategy was conceived long before the COVID crisis, yet COVID also presents a golden opportunity to invest in regions and promote working remotely. The world has changed and transit has to change too, the biggest risk is doing nothing, staying with the status quo. The emerging Japanese MaaS vision is unique in that Japan has a golden opportunity of leveraging the national Transit IC card standard into something new, taking it into the next era…if old rivalries and sectarian interests don’t get in the way and blow it, that is. Either way the next few years will be a very interesting time for Japanese transit.

The PASPY thing

HIroden, NEC and LECIP team up for the new system announcement that replaces IC smartcard PASPY in 2024 (Hiroshima Home TV)

PASPY announced today that PASPY transit IC card service ends March 2025. The official replacement has been announced, billed as the “the fist Account Based Ticketing system in Japan” (yeah right) and launches October 2024. Main PASPY operator Hiroshima Electric Railway Co.,Ltd. (Hiroden) has been thinking out loud since last May that they planned to go all in with a QR Code smartphone app. Twitter users complain, a lot, that QR will be an inconvenient pain in the butt over what they have now.

Here’s the thing, most people assume that killing PASPY card means Hiroden and Hiroshima region PASPY transit partners will rip out all the FeliCa readers and replace them with optical code readers. I don’t think so. FeliCa PASPY cards will disappear but not the transit IC readers. If you listen carefully to Hiroden’s bitching and moaning about having to shoulder PASPY system costs from the PASPY/FeliCa fare processing server side (that the PASPY partners don’t help us enough with…boo-hoo-hoo). Dump that and get out of the plastic card issue business, leave ICOCA / Transit IC readers where they are and let them handle their own fare processing, retrofit a QR scanner or install Denso Wave QR+NFC readers, toss out a QR PASPY app and the PASPY associates can call it a day.

PASPY had all the limitations of region transit cards: no e-money functions for store purchases to juice the recharge business side, slowly declining ridership, and the card could not be used on JR West ICOCA and larger Transit IC network…limitations that the Suica 2 in 1 Region Affiliate program resolves. Too bad JR West doesn’t have a similar program for the ICOCA region but it says something about JR West and local government relations that Hiroshima City and prefecture officials have kept quiet.

Nevertheless, there are way too many ICOCA and Mobile Suica users out there and Mobile ICOCA goes live 12 months from now. PASPY partners will want to keep those users riding no matter what Hiroden ends up doing. And local government transit subsidies will help keep the Transit IC readers in place. The whole point of transit is encouraging people to use it…right? And if it all works out, for QR based PASPY MaaS with Transit IC support, all the better.

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.

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.
