Go for it Tim! It will undoubtedly help Apple sell more global FeliCa iPhones because Smart Octopus on Apple Pay is a great marketing angle for the iPhone XR/XS models with Express Card power reserve and bulletproofed FeliCa performance. I have yet to experience a single Apple Pay Suica gate error from my iPhone XS with daily use since the launch date.
Update It occurred to me after posting the above that Apple has introduced transit cards and the technology behind them with larger point releases: iOS 10.1 for Suica (FeliCa) and iOS 11.3 for Beijing and Shanghai Transit cards (Apple flavored PBOC 2.0 ED/EP). In this scenario iOS 12.2 is the logical starting point for Smart Octopus on Apple Pay. However, Octopus is FeliCa which has been part of Apple Pay for over 2 years, Apple has ample engineering and testing experience with the technology to add Smart Octopus with a smaller point release, or none at all which was the case with contactless student ID cards.
Update 2 The original source reports pointed to an end of January rollout, now that iOS 12.1.3 is released we will see how it plays out between now and iOS 12.2. Considering the Apple Pay Suica launch meltdown on iOS 10.1 update day, Apple would be wise to launch on a quiet network day as Smart Octopus Apple Pay day 1 user additions will far outstrip any regular credit card Apple Pay rollout, the use profile for prepaid transit cards is very different.
iOS 12/watchOS 5 Suica performance continues to be a very mixed bag for many as Apple closes in on the iOS 12.1.3 update. There are no showstoppers but glitches are constant enough that there’s even an Reddit thread on the subject, a first. Suica performance glitches fall in 4 basic patterns:
Suica Express Card error flicker: occasional error flicker at transit gates with iPhone 7, iPhone 8, iPhone X (Rev. B) and Apple Watch 2~4. This is a completely different issue from the iPhone X NFC hardware defect. There is no workaround and will likely be fixed in an iOS update at some point…we hope.
Dead Suica Notifications/No Suica Balance Update: Suica Notifications stop working and Suica Balance fails to update at transit gates, store readers and Suica recharges. This affects iPhone 7, iPhone 8, iPhone X (Rev. B) and Apple Watch 2~4 but is easy to fix by putting Suica in Service Mode for a few seconds.
Slow or unresponsive Suica Recharge: this is probably more of a backend system issue between Apple Pay iCloud and Mobile Suica than iOS 12 but Apple Pay Suica recharge fails half of the time on the first attempt. This affects all devices and there is no work around except to try again. The Mobile Suica maintenance this month (January 2019) might help.
Express Card power reserve mode kicks in with iOS up and running. This only affects iPhone XS and iPhone XR. Express Card power reserve mode kicks in for some reason when it should not. Suica still works fine but the Apple Pay Suica UI stops working. No notifications, no balance update, nada. Service Mode does not revive Suica notifications but the fix is simple: restart iPhone and all is good.
No sooner than Apple issued the iOS 12.1.2 update that JR East pushed out a Suica system notice in their iOS Suica App: When Suica Balance Fails to Update. I guess this really means that Apple still hasn’t fixed iOS 12 Apple Pay Suica performance issues for everybody. My experience with iOS 12.1.2 on iPhone XS has been good so far but it takes time to find out what Suica performance on any iOS release really is. Whatever the case may be, fixing dead Suica notifications and a lost Suica Balance is very simple.
Put Suica in Service Mode and let your device sit for 10~15 seconds, then quit Apple Pay or simply put the screen to sleep. A Suica Notification will then appear with the updated Suica balance. Let’s hope that Apple’s New Year resolution list includes quickly fixing Apple Pay Suica performance issues.
The CreditCard no Yomimono site (CCY) has collected and listed all the FeliCa contactless card issued to date numbers released by Japanese companies in 2018 into one convenient table. WAON is missing because AEON didn’t release any numbers this year, CCY estimates WAON card numbers at 70 million . The numbers are fairly recent and roughly inline with the Japanese fiscal year through early 2018. They are very interesting but as CCY points out the number of issued cards does not always translate into actual use: previous surveys indicate that Rakuten Edy is used much less frequently than Suica at the cash register.
Prepaid Transit IC cards (Suica, PASMO, etc.) are by far the largest at 143,700,000 which means that every person in Japan has at least one. CCY also notes the explosive 51% growth rate of QUICPay which they attribute to Apple Pay. This is one half of the story. JCB has certainly done an excellent job of working with Apple Pay but I suspect another reason is that Japanese Apple Pay Suica users switched from using Japanese issue VISA cards that don’t support Apple Pay Suica recharge in favor of QUICPay cards like JCB VIEW that do.
