INDIANAPOLIS -- They're billed as faster and more convenient, but some high-tech credit cards could be opening customers up to identity theft.
In 2005, JP Morgan Chase was the first to unveil an RF credit card, equipped with radio frequency technology that allows customers to skip swiping and simply wave the card in front of a special reader.
Cards with radio frequency identification technology, commonly known as RFID, are now used by all of the major credit card companies, including Discover, VISA, MasterCard and American Express.
