American Express has announced that it will add the ExpressPay RFID-based payment system to all new Blue cards issued by the company. The ExpressPay card will also be tested in select branches of a number of chain stores, including 7-Eleven, CVS and Ritz Camera. The feature, which is already in the test phase, is similar to the "blink" card being tested by JPMorgan Chase. Like Chase, Amex says the ExpressPay system is as secure as traditional charge cards, and the company provides its standard fraud and theft protection as well. Not that we don't trust you or anything, Amex, but excuse us if we leave home without it for now.
