Mobile Suica as the default Japanese corporate transit card

After posting about the surprise rise of Mobile Suica payment use it occurred to me that I failed to take the corporate transit angle into consideration. COVID has been hard on transit companies in many ways, especially now that there is much less need for commuter passes. But it has also been kind to Mobile Suica in unexpected ways, the appeal of Express Mode for transit and purchases that doesn’t care about face masks is undeniable, and Transit IC mutual compatibility lets Suica work as a national transit card. Japanese corporations are leveraging this last point as Mobile Suica takes care of nationwide corporate transit needs, and takes care of the travel expense accounting.

While there isn’t a need for dedicated commuter passes for people working remotely, companies still need to reimburse employees for travel they still need to do. Calculating and reimbursing plastic transit cards is a pain as it is for paper tickets. Mobile Suica as corporate transit card has several advantages here, it works nationwide for regular transit, for Shinkansen eTicketing (EX, Eki-Net eTickets, Touch and Go), for travel incidentals (taxi, meals, etc.), and it is much easier to pull itemized travel details online from Mobile Suica accounts.

The biggest advantage of Mobile Suica is SmartGo Staple and SAP Concur online integration with live JR East Suica transaction records for much easier corporate travel expense accounting. SmartGo is particularly compelling as it matches Mobile Suica account expense reporting with a corporate VISA prepaid card option, removing the need for monthly employee reimbursement. This matchup of SAP, SmartGO and Mobile Suica has made Suica the default transit tool for COVID era corporate Japan.

JR East Ticketless Touch and Go Shinkansen expands system wide

The yellow area is new

Another day, another Suica related announcement. JR East ticketless Touch and Go Shinkansen service for Suica and other compatible Transit IC cards will be expanded to include all JR East Shinkansen lines in March 2021. Touch and Go differs from Eki-Net Shinkansen eTickets in that Touch and Go uses the Suica balance for Shinkansen fare, eTickets do not.

The service is very simple: register Suica, PASMO, etc. at any JR East station pink recharge kiosk for Touch and Go, or register Apple Pay Suica using Suica App. After registration all you do is go through the Shinkansen gate and get on a non-reserved Shinkansen seat. A typical use case looks like the diagram below.

JR East and Apple Quietly Fix a Suica Weakness

One of neat things about Apple Pay Suica is how easy it is to add, delete and migrate Suica cards to different iPhones. iCloud and Mobile Suica keep the Suica card information and balance safe and secure no matter what device it’s on.

There was one weakness however: the Suica card ID number changed every time the card was deleted and re-installed in Wallet. This was a problem for other apps that used the Suica card ID to soft link a service, such as JR Central smartEX. If the Suica card ID changed and the user forgot to manually update the new Suica ID number, the service stopped working. This is exactly what happened to me the first time I used smartEX.

This also applied to Suica Coin lockers which use the Suica card ID to lock and unlock. While it was highly unlikely anybody would delete and re-install an Apple Pay Suica card with their stuff locked away, the possibility was there.

Fortunately Apple and JR East have fixed this weakness. Now when you delete a Suica card from Wallet and re-install it the Suica ID number stays the same. JR East did not advertise the change but I suspect it was put in place the same time Touch and Go Shinkansen launched on April 1. Touch and Go soft links the Apple Pay Suica card ID number when you register.

With the new changes in place manually updating Apple Pay Suica ID numbers is a thing of the past.

UPDATE: the Suica ID number stays the same when deleting, reinstalling and migrating on iPhone but changes when transferring from iPhone to Apple Watch. I have not confirmed if Suica ID changes back to the original ID number or another new ID number when transferring Suica back to iPhone from Apple Watch.
