Abstract

A biometric access control system and method for currency-handling machines such as merchandise vending machines, payphones, copy machines, video game machines, pool and pin-ball machines, slot machines, parking meters, and automatic teller machines has two principal components—a digital authentication device (“DAD”) that is installed within the currency-handling machine, and a mobile biometric data collection device (“MDCD”) that a currency-handling machine servicer takes with him or her along his or her currency-collection route. In operation, a previously-collected reference biometric template for a servicer is stored on the MDCD and compared with a fresh biometric sample taken by a biometric sensor built into the MDCD. An authenticated servicer is then provided with access to the currency-handling machine. Preferably, the MDCD also maintains an audit trail of the time and location of each access attempt and the identity of the servicer.

Claims

1. An access-controlled currency-handling machine comprising:

a currency repository that holds currency received and/or dispensed by the currency-handling machine;

a door that, when opened or removed, provides access to the currency repository;

an electronic lock mechanism operable to unlock the door to thereby provide a servicer attempting to obtain access to the currency repository with access to the currency repository;

a digital authentication device installed within the currency-handling machine, wherein the digital authentication device is operable to send a signal to cause the electronic lock mechanism to unlock the door;

the digital authentication device having a communications interface operable to receive a biometric reference template and a biometric sample from a mobile biometric data collection device carried by the servicer; and

the digital authentication device having a processor operable to compare the biometric reference template with the biometric sample to authenticate the servicer attempting to obtain access to the currency repository and, upon identifying a match, to send a signal to cause the electronic mechanism to unlock the door.

2. The access-controlled currency-handing machine of claim 1, wherein the access-controlled currency-handling machine is a vending machine that dispenses merchandise or provides amusement to customers that insert a designated amount of currency into the machine.

3. The access-controlled currency-handing machine of claim 1, wherein the access-controlled currency-handling machine is a refrigerated beverage vending machine that dispenses cold beverages to customers that insert a designated amount of currency into the machine.

4. The access-controlled currency-handing machine of claim 1, wherein the access-controlled currency-handling machine is a snack food vending machine that dispenses snack foods to customers that insert a designated amount of currency into the machine.

5. The access-controlled currency-handing machine of claim 1, wherein the access-controlled currency-handling machine is a copy machine that makes copies for customers that insert a designated amount of currency into the machine.

6. The access-controlled currency-handing machine of claim 1, wherein the access-controlled currency-handling machine is a parking meter that provides a user that inserts a designated amount of currency into the machine with authority to use a parking space.
