Filed:

Jun 3, 1986

Appl. No.:

6/870005

Inventors:

Norman S. Burkhardt - Westminster CO

Assignee:

Intellicard International, Inc. - Colorado Springs CO

International Classification:

G06K 708
G06K 1906

US Classification:

235438

Abstract:

A device and method for transferring data from a microprocessor located in a transaction card through a card reader by emulating a prerecorded magnetic stripe on a conventional transaction car such as a credit or debit card. Data is sequentially produced by the microprocessor within the card and applied to a magnetic field generator which produces magnetic fields that emulate prerecorded data on a conventional magnetic stripe of a transaction card. This allows transfer of data from a microprocessor to standard card readers without the necessity of substantially modifying the card reader device. Circuitry is also provided for detecting the position and speed of movement of the card through the card reader to ensure that all of the data is transmitted from the microprocessor to the magnetic field generators within the scanning time of the card across read head of the card reader.
