Most cards here have the chip, I think. You mean how to put the card next to a reader and it goes beep, yeah? Those are available, but for some reason restaurants and drive through food places just...don't do that? The only place I think that uses the tap part is something like Red Robin, a fast casual burger place. They have machines on the table you can tap. But for the most part you hand the card and the check/slip to the server, they disappear, return with a thing to sign and your card. But from my understanding it's pretty easy to do chargebacks on the card or the like if someone were to charge extra or the like. But part of the reason for handing you something to sign is because you also can put the tip on there, being in the USA.
