Time and time again..I end up mis placing my card in one jacket pocket or another or forget to put it back into my wallet and end up loosing it. I believe it was Mastercard came out with the small credit card that attaches to your key chain…that you can swipe at the counter. I thought it would be a great idea for your company to do the same..so forgetful people like me wont loose their cards. Since I drive to Starbucks everyday, I always have my keys with me!! Yes..I know you can register your cards…yada yada yada! lol
