Abstract

1392040 Credit card BURROUGHS CORP 12 April 1972 [13 Oct 1971] 16933/74 Divided out of 1392038 Heading G4M The description is the same as that of Specification 1392038, but the claims relate a record medium having separate magnetic data and identification tracks each containing the same information and with the identification track having latent and active states, both states containing the data but with the data only being machine readable in the active state and to a method of producing the record medium.
