Apple hit the on switch for contactless student ID cards today. The press release has nice photos but is vague. There is much more detail on the Apple support doc Use student ID cards in Wallet on your iPhone or Apple Watch.
The most interesting detail is the device eligibility: iPhone 6 or iPhone 6 Plus and later, Apple Watch Series 1 and later and Express Mode isn’t available on iPhone 6 or iPhone 6 Plus. NFC-A/B, definitely not FeliCa powered as some sources were saying and could be MIFARE. It looks like Blackboard has something else up their sleeve for middleware but I’m willing to bet you that Student ID Express card performance is slower than Apple Pay Suica Express Card with power reserve even on the same iPhone XS/XR device. The Blackboard IC card format is both FeliCa and MIFARE but the eligible device list suggests student ID cards are PassKit NFC Certificate powered MIFARE Host Card Emulation (HCE).
The rest of the support doc details confirm the cards are stored value (SV) with Express Mode and students can recharge them with Apple Pay, a credit/debit card in the eAccounts app or cash at the “school’s self-service machines”. In other words it’s just like Suica App and Apple Pay Suica for door locks instead of transit.
There is conflicting information about the Blackboard technology used for Apple contactless student ID cards. The Express Card function is exactly what FeliCa offers and Blackboard supports. On the hardware side iPhone 6/6 Plus and later all have NFC A-B-F chips as do Blackboard NFC readers.
The Blackboard IC card format uses both FeliCa and MIFARE and Blackboard has been migrating IC cards to MIFARE. The implementation appears to be PASSKit NFC Certificate powered card MIFARE HCE. Apple has not publicly announced MIFARE support but it is the only technology compatible with Blackboard IC card formats that could power the express card features of iOS 12 student ID cards across all eligible devices.
