What happens when the merchant doesn't care he's paid by the right customer?

How does the system handle the common use-case where you give a third party (wife,friend,kid,..) the money to go and pay the bill.

Both Facecash and now Square Card Case have this problem, but maybe I have missed something.

Same as with credit cards: There'd be lots of fraud complaints. Square will realize there's a problem and depending on what their contracts look like they'll either charge them heavy fees and/or fine them to fund having to deal with the fraud, or cut them off.

Credit cards has this exact same problem. Physical control of the card pretty much gives you free reign to pay for stuff - most shop staff can't even be bothered to look at the signature or ensure the name has any chance of being yours.

The article states the current app already allows you to press a button to pay, so presumably you just forgo the convenience and make them press the button if their face doesn't match up.

And/or add a way of adding additional authorized people whose images will show up.
