Sure, that would be one way to hack around it. I'm wondering, specifically, if Stripe Checkout[1] will ever gain Apple Pay support. Presumably it's up to Apple to expose the relevant API to javascript.
Yeah, this is what I meant by my confusing question above.
One day they'll probably let you enter your user id and password to get it started then scan your fingerprint on a device to confirm. Why not?
my only issue with this has to do with the occasional lapse in recognition of the touch ID. if it can't read your fingerprint several times, it asks for your password code. touch ID is of course not theft-proof, but initially it's a slightly greater obstacle than a simple numeric code.
It would be beyond easy to make a generic app that registers a custom protocol handler on the phone that could handle this. Don't know if Apple would approve it but sending the user to, for example, myapplepayapp://transactions?Id=123 where the id could be used to grab all the order data from the shopping cart, identify the merchant, and grab their Stripe API credentials would be simple and useful.
