For added security against fraud, a financial services card such as a credit card is paired with a separate tag such as an RFID tag. A system for minimizing fraud includes a card reader for reading a card ID, a tag reader for reading a tag ID, and a controller for comparing the card ID with the tag ID, and approving or rejecting a card transaction based on the comparison. A method for minimizing fraud includes reading a card ID from the financial services card, reading a tag ID from the tag, comparing the tag ID with the card ID, and approving or rejecting a transaction based on the comparison. The card reader may send a security stamp to the tag, which may combine and encrypt a partial tag ID and the security stamp to provide the tag ID.
