My client has an NFC loyalty card for their customers. Since a lot of their customers lose their card or break it they would like to make the card available in Host Card Emulation mode. We're talking hundreds of thousands of card holders, so the advantage of emulating it is huge for them. Is it possible to do this (yet) on the current version of iOS? If so can it be triggered from within an app or is Apple Wallet a solution for this? As it will be available on the Android version of the app I am looking for an elegant way to integrate the same functionality on Apple devices. Please advise.
