System for voucher or token verification
First Claim
1. A method for verifying a voucher or token, comprising:
- recording a code associated with the voucher or token;
scanning the voucher or token to retrieve the code at a cashier'"'"'s station;
querying a voucher or token database for information associated with the code; and
determining whether the voucher or token is valid, using the information, wherein the cashier'"'"'s station uses a first communication link coupled to a back room computer, but the querying step uses a second communication link different from the first communication link.

Abstract
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.

13. A system which verifies a voucher or token, comprising:
-
a cashier'"'"'s station which uses a first communication link with a back room computer;
a voucher or token database which stores at least one of a code and a value associated with the voucher or token;
a recognition subsystem which reads the code from the voucher or token;
and first and second transceivers which form a second communication link, different from the first communication link, wherein the second communication link couples together the voucher or token database and the recognition subsystem. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A system which verifies a voucher or token, comprising:
-
means for recording a code associated with the voucher or token;
means for scanning the voucher or token to retrieve the code at a cashier'"'"'s station;
