Rethinking Face ID in the Face Mask Touchless Era (Updated)

When iPhone X came out in November 2017, IT journalist Tsutsumu Ishikawa named Suica the Apple Pay winner. What he really meant to say was that Suica Express Transit was the only easy way to use Face ID Apple Pay. It took me a long time to get used to Face ID Apple Pay but now with the COVDID-19 crisis and regulation face masks, the choices are back at square one: (1) yank down the face mask to Face ID anything, (2) use a passcode instead, (3) use Apple Pay Suica set with Express Transit. Yeah, the last one. More people have Express Transit now in China, TfL-land and little bits of the MTA OMNY system but nobody has it for purchases. Except Apple Pay Suica, still the only Express Transit card for contactless payments at stores.

In the sudden era of face masks and plastic curtained checkout areas, dealing with Face ID as little as possible, and using Apple Pay Suica as much as possible, makes life easier and safer: experts in Japan instruct people not to touch face mask surfaces and you don’t want to be yanking down a face mask to use Face ID Apple Pay at close proximity checkout. The interim solution is Apple Pay on Apple Watch which does not use Face/Touch ID at all. But there is that social distance problem: your arm has to reach the reader. That’s the thing about NFC, it’s close proximity technology. So are QR Codes.

The Touchless Distance
When I first saw the NTT Docomo Ultra Wideband Touchless Mobile FeliCa demo I though why would anybody want to pay a few feet away from the reader? Outside of paying while sitting in the drive thru I could not think of a reason. After living with Face ID, face masks and COVID-19 social distancing, I see the reason now at every checkout at every store. I want it. You will too (the 1:20 mark):

And for cars too, CarKey will work like this at some point (0:13 mark):

Touchless Transit Gate vs Facial Recognition
The COVID-19 crisis upends another Face ID related technology fantasy: facial recognition transit gates. NEC is working on face recognition that works with face masks. If anybody can deliver viable face recognition with face masks NEC will certainly be one of the first, but there are cost, performance and privacy issues to consider for transit gates: how fast is the transaction speed, how well does it scale for commuter rush, how do you register faces? Who controls all that transit gate face data and is it stored domestically or data farmed out internationally?

Mobile FeliCa and MIFARE Touchless is the same device level security model we have now with Apple Pay Suica and Student ID, and what we will have with CarKey and shared ‘keys’. UWB is a new hardware layer on top of what already exists, it bridges the NFC infrastructure and contactless payment methods we have now and extends it to the future instead of junking it.

Osaka Metro plans to have face recognition transit gates deployed in time for Osaka Expo 2025. It’s a risky transition plan. Touchless transit gates are the safer bet. Sony, Docomo, NXP, JR East, JREM are doing the necessary hardware and software development with the same embedded secure element security and local processing architecture we have now. Osaka Metro can buy the finished goods from them instead of reinventing the wheel.

Fixing Face ID Shortcomings
On the smartphone side Apple already has the Ultra Wideband U1 chip in iPhone 11. The next step is Apple Pay support as outlined in the iOS 14 Apple Pay post. I hope Apple uses the opportunity of adding UWB Touchless Apple Pay to enhance Face ID with improved technology and controls. Express Card/Express Transit is the Apple Pay method to bypass Face/Touch ID for transit, purchases (Suica) and ID door access (Student ID and CarKey). Extending the Express Card/Express Transit model as much as possible, while keeping the high level of security, is one practical way Apple Pay can address some of the Face ID in face mask era pain points.

Longer term, Face ID has to evolve to securely read faces with face masks reliably. If Face ID cannot be secure, intuitive and face mask user friendly, I don’t see a future for it, or being the iPhone model that customers want to buy. This is why iPhone SE is looking like Apple’s most important product launch of 2020.

Last but not least I don’t see Open Loop transit ever working with Touchless technology. Open Loop will likely remain a NFC only service because EMVCo partners are invested in lower common hardware standards like ISO14443 and plastic cards and probably loath to update them. Certainly they don’t want to lose the plastic card issue business because it’s more profitable than issuing digital ones. EMVCo certainly didn’t see the current situation coming, nor did Apple of course. But then again who did?


UPDATE

iOS 13.5 beta 3 has a Face ID tweak: when it detects a face mask it no longer delays the swipe up Passcode pop up with a 2nd read attempt, it goes straight to Passcode pop up. This small tweak remove a tiny bit of Face ID with face mask stress, but tiny things add up when unlocking iPhone many times a day. But for me Passcode pop up was only one stumbling block, a second bigger stumbling block is Passcode entry via the numeric keyboard.

There is a curious lag between what your fingers are tapping, the feedback click sound and what tap the iPhone actually registers. If you closely inspect the visual tap feedback, it flashes white then fades slowly, while the click just clicks.Taken all together, my brain wants to type fast and tells me the my 2 thumb input is going fast, but the iPhone Passcode numeric keyboard wants me to type slow with 1 thumb. Perhaps it’s just me but I only get correct passcode entry 50% of the time unless I slow way down and type with 1 thumb.

Overall the Face ID with face mask tweak seems more for iPhone unlock, it’s much less useful for Apple Pay. I hope Apple continues to tweak Face ID before iOS 13.5 ships but the reality is Apple can’t do very much in a short time.

John Gruber had an interesting observation regarding another iOS 13.5 beta 3 tweak, this one for Group FaceTime:

methinks a lot of folks at Apple (executives included) are using group FaceTime chats more than ever before lately, and have realized that in practice, especially in larger groups, it’s not a good experience.

Unfortunately it’s the same for Face ID: Apple is only addressing it because Apple execs are wearing face masks. It’s very frustrating that Apple is only dealing with the Face ID with face mask issue now that it’s on their face. Customers in Asia have been wrestling with it since iPhone X day one November 2017. At any rate I hope Apple puts the experience to good use for a better future version of Face ID.
