Meh. Looks like more trouble that it's worth. With the new(ish) RFID chips, I can "swipe" a credit card without taking it out of my wallet. If I wanted a "secure PIN" feature, I could use my ATM card. Maybe I'll change my mind if my credit card were ever stolen, but until this, this seems like an sounds-good-but-is-actually-useless kind of feature.
Banks seem to be backing away from the RFID cards. My new card came without one. I called and asked them why and they said they were less secure. Personally, I love the new cards. Unfortunately, NYC cabs and CVS are the only place where you can find the readers.
