Patent ID: 10002477

Abstract:
Electronic delivery of counterfeit-resistant documents exchangeable for value such as admission tickets, gift certificates, coupons, vouchers, etc. directly to the person who ordered the documents over an open communications network such as the Internet. A first party orders a document from a second party, and the second party electronically delivers the ordered, counterfeit-resistant document to a device designated by the first party. For example, the document may be electronically ordered using a PC, and a printer coupled to the PC may print the document. Alternatively, the electronic information may be provided to a fax, or the document ordered by telephone and electronically delivered to a PC or fax. The document may be made counterfeit resistant by assigning unique information to each document of a given type, e.g., admission tickets, and checking the uniqueness of a document prior to allowing it to be exchanged for value.
