Apple’s decision to offer Apple Pay EMV style Express Transit as a default iOS 13 feature on the work-in-progress that is MTA OMNY may not have been a smart idea after all. Those manual swipe MetroCards will be around for a few years, and with Cubic Transportation running the show it is anybody’s guess when OMNY, the system and the MIFARE MetroCard replacement, will completely in place and running smoothly.
For every tweet saying Express Transit is great, there are plenty of complaints of unwanted OMNY charges because iPhone users didn’t know Express Transit was turned on. The thing is iPhone and Apple Watch have to be damn close for a read. Unless the device is in a pants or coat pocket that brushes on the OMNY reader, I don’t see how accidental reads can happen. Nevertheless Apple would have happier New York City customers leaving Express Transit off by default…at least until OMNY is completed and running smoothly everywhere…whenever that is.
Well that’s a nice way to solve a iPhone X Suica NFC problem: upgrade to iPhone 11. Suica performance on Apple A12 Bionic and A13 Bionic iPhone models is a whole new level over previous models thanks to the Secure Enclave design that bypasses iOS for transactions and also gives us Express Cards with power reserve. I love that he loves Suica again and says goodbye to QR too.
Nevertheless, people like me are intrigued by the multiple Express Transit card support in Wallet for native transit cards and EMV payment cards. I use Apple Pay Suica everyday and decided to turn on EMV Express Transit to see if there is any performance overhead. There is.
After a week of testing I can definitely say that turning on EMV Express Transit and using Apple Pay Suica is a bad dance. Express Transit momentarily forgets which way the NFC reader needs to spin. Instead of a smooth Suica waltz, there is a momentary pause and uncomfortable interlocking of arms. EMV Express Transit seems to introduce some new NFC dance steps into the usual read/write process that slows things down at transit gate readers a little and store readers by a noticeably wide gap.
Take it with a grain of salt as I can only test Apple Pay Suica + EMV Express Transit on a single iPhone XS running iOS 13 beta 7. Other devices running iOS 12.4 or the official iOS 13 release may be OK. A good rule of thumb is to forgo multiple Express Transit cards and stick with a single Express Transit card. Leave EMV Express Transit off if you don’t need it.
I’d love to hear any Apple Pay Suica + EMV Express Transit user feedback, please tweet @Kanjo if you have some observations to share.
Apple’s strong point is the tight integration of software services across different devices that no other platform can match. Apple Pay Suica works on iPhone and Apple Watch, but the latter combination of technology, function and size makes it a completely different and beguiling experience. Apple Pay on Apple Watch is its own special thing.
A Temporary Split in the NFC Evolution Line? The evolution of Apple NFC on both iPhone and Apple Watch was in lockstep up until the arrival of A12 Bionic in 2018. The A12 Bionic NFC powered background tag and Express Transit power reserve features only work on iPhone XS/XR. Apple Watch Series 4 does not support these NFC features, nor does watchOS support the Core NFC framework, this means that NFC tag Apple Pay on Apple Watch is out of the question.
Is the feature split temporary or does it represent a different line of NFC evolution for Apple Watch? The absence of Core NFC makes sense because watchOS does not support 3rd party apps, at least not yet. Express Transit power reserve however, would be a great feature to have on Apple Watch as iOS 13/watchOS 6 Apple Pay Express Transit rolls out to Chicago Ventra, Brisbane myki and Hong Kong Octopus.
Getting that feature on Apple Watch depends on how quickly Johny Srouji’s A team can implement the A12 Bionic Secure Enclave design that handles basic Apple Pay transactions directly and bypasses the OS, on the S Series chip. I cannot believe they are not pushing hard to deliver the goods as soon as possible, perhaps even with Apple Watch Series 5 featuring a S5 Bionic chip.
Delivering a S5 Bionic would get Express Transit power reserve on Apple Watch with NFC performance gains as well. It would also give Apple the option to add NFC background tag reading later on as watchOS becomes more powerful and independent.
The iPhone 7 FeliCa Question There is one fuzzy area of iOS 13 Core NFC and it is iPhone 7 FeliCa support. At WWDC19 Apple announced that all devices, iPhone 7 and above, would support the enhanced NFC tag lineup: NDEF, FeliCa, MIFARE, ISO 7816, ISO 15693, VAS. But this does not match up with Apple’s own device specs for adding a FeliCa Suica card to Apple Pay:
Apple is telling developers that all iPhone 7 models are good for FeliCa but telling customers that only iPhone 7 JP models are good for FeliCa. This means we get one of two scenarios:
iOS 13 retroactively adds FeliCa support to all non-JP iPhone 7 models. Apple can do this by adding device specific FeliCa keys as iPhone 7 NFC hardware is the same for all models worldwide.
iOS 13 Core NFC FeliCa tags work but non-JP iPhone 7 models (without FeliCa keys) do not work for FeliCa transactions at the terminal.
The latter ‘FeliCa keys vs. No FeliCa keys’ scenario is illustrated in a comment post by Reddit user FelicaDude, if I understand correctly, that without device specific FeliCa keys iPhone 7 only works in basic Read/Write mode without encryption, with FeliCa keys iPhone 7 works in Read/Write encryption mode necessary for local offline processing with payment terminals (i.e. Suica):
The international iPhone 7s can do basic FeliCa read/write without encryption, because they embed a FeliCa-capable CLF <contactless frontend>. Apple has chosen not to provision them with Osaifu-Keitai keys, probably to avoid paying royalties to FeliCa Networks for each device.
As I wrote previously, “if you are using iOS 12.3, you are already using iOS 13 Apple Pay Wallet.” The major under the hood Wallet changes of iOS 12.3~4 were completed ahead of iOS 13 for the Apple Card rollout that is coming very soon. For Apple Pay Suica users, and Express Transit users everywhere, the solid Express Transit performance of iOS 12.3~ iOS 12.4 and the UI, are exactly what you get in iOS 13. There is nothing new, a good thing.
The only changes are Suica Notifications which have lost 3D Touch shortcuts for Recharge and Commute Plan Renewal. Since 3D Touch is on the chopping block in iOS 13, this is not unexpected, but it is unfortunate: the recharge shortcut was handy and finally useful with the robust iOS 12.3 Suica Recharge performance. Suica Notifications are still a work in progress however, witness the useless ‘In Transit’ Suica notification, hopefully shortcuts will reappear in some form before the final release.
