Abstract
A secure property document and system are provided which prevents the use of fraudulent credit cards and other documents. The documents each include optical and magnetic data sets. Each data set contains data elements having a spacial relationship to at least some of the data elements contained in the other data set. The system reads and processes the data to determine whether or not the spacial relationship corresponds to that recorded for the particular document. If the spacial relationship codes do not agree within predetermined limits, the document is rejected by the system, whereby the transaction may be refused or additional information requested from the document holder.
