RFIDs in Credit Cards Create Privacy Problems

Yesterday, the New York Times published a troubling article about remotely-readable credit cards using Radio Frequency Identification (RFID) technology:

"[I]n tests on 20 cards from Visa, MasterCard and American Express, the researchers here found that the cardholder's name and other data was being transmitted without encryption and in plain text. They could skim and store the information from a card with a device the size of a couple of paperback books, which they cobbled together from readily available computer and radio components for $150.

"They say they could probably make another one even smaller and cheaper: about the size of a pack of gum for less than $50."

Read the whole thing here, and learn more about RFIDs.
