New credit cards convenient, and dangerous?

The new credit cards make life easy. You wave them in front of the gas pump and it’s over. Nothing to sign. No wait for clearance.

But they are also dangerous. These cards have a “Radio Frequency Identification Device” (RFID) buried inside them . The RFID transmits a signal with all your information to a receiver when it gets close enough.

There is no guarantee that these cards will not transmit when you do not want them to. For example, you could pay for someone else’s gas just by walking past the pump when they are filling up. Or, worse, a sophisticated crook could set up a receiver of their own and steal your data when you are making a legitimate charge. They could then duplicate your credit card and go on a shopping spree.

Probably best to avoid them until we are sure they are safe.
