Abstract

A method of counting and validating the value of a currency document includes the steps of sensing at least one coded tag printed on the currency document; determining a scanning time at which the sensing device sensed the coded tag; determining from the sensed coded tag and determined scanning time a unique identity of the currency document; comparing the unique identity of the currency document with a list of suspect identities to determine a validity of the currency document; and determining a value for the currency document from the unique identity.

Claims

1. A method of counting and validating the value of a currency document, the currency document having printed thereon a repetition of identical coded tags, the method comprising the steps of:

sensing at least one coded tag from the repetition of coded tags printed on the currency document;

determining a scanning time at which the sensing device sensed the coded tag;

determining from the sensed coded tag and determined scanning time a unique identity of the currency document;

comparing the unique identity of the currency document with a list of suspect identities to determine a validity of the currency document; and

determining a value for the currency document from the unique identity and determined validity.

2. A method according to claim 1, wherein the step of determining the value of the currency document values only currency document that are determined to be valid.

3. A method according to claim 1, further comprising a step of communicating to a remote database the unique identity of the currency document to compare the unique identity of the currency document with the list of suspect identities.

4. A method according to claim 1, further comprising a step of communicating with a remote database to download and store locally the list of suspect identities.

5. A method according to claim 1, further comprising a step of communicating with a remote database the unique identity of the currency document upon determination that the unique identity of the currency document matches an identity in the list of suspect identities.
