I remain confused about the difference between the "RFID" card and the chip and pin (or signature) card. My understanding (very possibly wrong) is that an RFID card can be read by a bad guy with a covert scanner at about 1 foot distance, or a bit more. Thus, when standing in line, almost anywhere, someone near you can hack your card while you just stand there with the card in your pocket.

In the USA, the RFID cards were promoted as being able to just be "waved" over the payment terminal instead of being "swiped."

Then came the present generation of "Chipped" cards which must be inserted into the terminal for several seconds.

It is totally unclear to me if the Chipped cards can be read and hacked from a distance, even if only a few inches. It appears they can, but I have no definitive information on this. Thus, given the lack of information, I use the RFID metal foil sleeves.

Any clarification, directly or a site to review, on this would be greatly appreciated and help in keeping the card secure.
