I wonder is it possible for tap-to-pay terminal to only support tap-to-pay credit or debit cards and not support Apple Pay/Google Wallet? That way, nobody has to deal with the fee issues of Apple Pay or Google Wallet.
If it’s at all possible it’s very difficult to do, that’s why they just shut off contactless altogether instead. That being said, what fee issues are you talking about? Neither Apple nor Google charge merchants any fees for accepting their mobile wallets; whatever the merchants’ reason is to not accept mobile wallets it certainly can’t be to save on fees that don’t even exist. Apple only charges participating card issuers for letting their cardholders use apple pay, but not the merchants for accepting it, and I believe Google not even that.
