Which metro cards? Navigo have been supported all year.
Apple's hardware doesn't allow for arbitrary card emulation - the logic has to run inside the Secure Enclave, and AFAIK that is an atomic block of firmware shipped along with the OS. No third party code allowed.
But they have added that secure enclave support for the various metro card networks, including "express pay" where NFC functions like metro cards will work even with the phone powered down due to low battery.
- concinds 5y agoYou can recharge Navigo but not load it onto your phone like with Apple Pay cards. That's only possible on Samsungs, not other Androids or iPhones, and even though according to one commenter this may not be the case much longer, I hate to see things that slow technical progress and QoL improvements down.
- dwaite 5y agoI looked more into it - you are correct, Navigo sounds like it still won't replace a physical card. My understanding is that do to patent royalties wanted by the underlying Calypso system, it was not merged into ISO 14443 and deviates in a few ways. Apple has historically implemented more of their NFC stack in hardware than other implementations, so there may be limitations as a result of the with communication with a card reader.
