"The standard credit card with mag strip does not require physical contact with the reader. All it requires is very close proximity. It's already "contactless". It's not RFID since it is reading magnetic rather than radio pulses."
"Something like 200 million 14443 RFID smartcards have been sold in the last ten years. DC's Metro system for example uses 14443 RFID smartcards.
Security measures used in these smartcards are quite good. I am unaware of any reports of 14443 cards being cloned or hacked, but to be honest, I haven't done much checking.
The next generation of U.S. passports will also use this same technology. New U.S. drivers licenses may also."
