摘要:
The present invention allows verification of a voucher or token prior to redemption. The voucher or token has a code associated therewith so that a value of the voucher or token may be stored in a database. Later when the voucher or token is presented to a cashier for redemption, the code is submitted to the database in order to retrieve the value associated with that voucher or token. In this way, the voucher or token is verified before redemption. In one embodiment, a verification system includes a voucher or token database, a recognition subsystem and two transceivers. The database knows the code and value associated with the voucher or token. A recognition subsystem reads the code from the voucher or token. The transceivers couple together the database and the recognition subsystem in such a way that the a query can be made by the recognition system to determine the value associated with the code or otherwise verify the validity of the voucher or token.
