What differences are there between using the technology on iOS and Android?

The main difference is that iOS devices have the Apple Wallet installed natively, i.e. cardholders do not need to install any additional apps. Android devices do not have that so we developed Yourwallet, an app that closely mimics Apple Wallet functionalities for non-payment cards. Apart from that the differences are minor: the placement of the button to flip the cards and other differences in the interface.
