ABSTRACT:
A customer prints a ticket that includes customer security features that appear on the printed ticket. The features, such as a digital photograph of the customer, are checked by the merchant when the ticket is presented. If the security features do not match a ticket holder's features, the merchant denies admission to the ticket holder. The background area of the printed ticket contains a pattern to make it difficult for someone to insert other security features onto the ticket. The printed ticket includes a barcode that can be scanned by the merchant for fast retrieval of the purchaser's security features previously provided by the customer to the merchant. The retrieved security features are compared to both the ticket holder's features and the security features that appear on the printed ticket. A discrepancy during any of these comparisons enables the merchant to identify the imposter and deny admission.
