Abstract
A chip card, such as a financial transaction card, having first identifying data written in a read-only memory portion of circuitry contained in the card, wherein second and third identifying data are respectively coded in a machine readable optically variable device (e.g., a hologram) and a magnetic stripe on the card. The authenticity of the card is verified by combining these different identifying data; for example, the second and third identifying data may be combined to produce an algorithm which is compared with the first identifying data for authentication of the card.
