Abstract
An identification recording data method for an identification medium includes the steps of printing or laminating an information identification bar code strip and then affixing a magnetic recording strip to the identification medium. A data set is encoded into N encoded data using N algorithms. The bar code strip has the N encoded data recorded thereon. The magnetic recording strip has the data set recorded thereon. The N encoded data is decoded and compared with the data set recorded on the magnetic strip. Comparision of the data yields a determination as to the integrity of the identification medium.
