A payment card may be read by a card reader which may include a sensing unit to read a magnetic component of the card. An authentication read may be used to collect a magnetic fingerprint of the card, and/or swipe characteristics of the authentication read. The magnetic fingerprint and/or swipe characteristics may be used for identification of the card and/or user, which may include authentication use of the card and/or detecting potential fraud. |
