I've had my MR credit card for almost a year now and so far the only times I have used the chip and signature technology have been in Canada and Europe. While I've seen several retailers in the U.S. with new credit card machines that can read the chip, all of them still use the magnetic strip (I've tried inserting my card in a few of these machines and none of the are programmed to use the chip yet).
Has anyone found a place in the U.S. that allows the use of the chip technology?
(See the Re: Anyone see that the MR Credit Card now has SmartChip Technology? thread from last year for more details about the MR credit card)
