They did trials using it to pay at McDonalds' drive-through on Long Island,

tapping a credit card doesn't slow the process down much.

McD's in the UK is one of the (relatively few) places where you can use
paywave credit cards. Although I always feel a bit awkward using a
credit card for such small purchases.

McDonalds in the Chicago area took Mobil Speedpass (a small black keychain
device) in the early 80s. It was a predecessor to today's paywave type cards,
except that it was tethered to a Mobil credit account. Although primarily
intended to pay for fuel at the pump at area Mobil stations, there were a few
other places it could be used.
