Abstract
An authentication system and method uses information on a position of a card as determined, for example, by detecting a position of a user's cell phone and the position of a card reader determined from card reader identification data. If the card is used in a card reader located near the user's cell phone, and the usual card authorizations are approved, it is determined that the card use is authorized. The position information thus serves as an additional level of security against a lost or stolen card.
