Abstract
The combination of a specially configured transaction card (10) and a magnetic pattern reader device (18) minimizes the power consumed by the operation of the smartcard format transaction (10). The transaction card (10) has a plurality of logically and electrically interconnected members, including at least one electromagnetic member with low magnetic permeability core element. The electromagnetic element generates a magnetic pattern. A logic processor member (16) controls the generation of the magnetic pattern. A self-contained energy source (14) powers the system. The magnetic pattern reader device includes a magnetically permeable element that has a higher magnetic permeability than that of the magnetic pattern generator. The magnetic pattern reader device is readably associated with the magnetic pattern generator so as to directly read the magnetic pattern.
