PASSIVE MAGNETIC TRANSFER OF DISCRETE MAGNETIC INFORMATION

摘要

A transaction record is prepared in both human and machine readable form by providing a card having both embossed data and magnetic data thereon and simultaneously imprinting the embossed data on a record card while transferring the magnetic data to a magnetizable portion of the record card. The magnetic data on the card is comprised of a plurality of discrete magnetic bits and is transferred to the magnetizable portion of the record card by subjecting the magnetic data and the magnetizable portion to a saturating prebiased D.C. field followed by a weaker D.C. transfer field.
