Authentication device, system and methods
View Patent ↗System terminal integrated with biometric sensor, such as a fingerprint sensor. Transaction terminal such as a point of sale system, automated teller machine (ATM) or other system. The system may include a touch screen display. Also, logic to process sales transactions may be included. The transaction terminal may include a cash drawer. The system authenticates users based on data from the sensor, and can regulate access, for example to a cash drawer, based on the authentication. Also described is a sensor module, security system, and method of operating a transaction terminal.
1. A point of sale transaction terminal for operation by an employee user to process sales comprising:
a display including a touch screen; a sensor physically and securely integrated into the display, the sensor receiving information from a human fingerprint from the employee user;
a cash drawer positioned within the transaction terminal for access by the employee user while using the transaction terminal;
means for logging on the user at the point of sale transaction terminal; means for starting a sales application after logging on the user; means for receiving transaction data from the sales application; authentication means for receiving a request from the sales application and for authenticating the user using a fingerprint from the sensor means in response to the reguest; cash drawer opening means for opening the cash drawer in response to the authentication means; means for recording the transaction data and fingerprint data from sensor and for transmitting the recorded data to a memory.
2. The transaction terminal of claim 1 ,
wherein the sensor comprises a solid state capacitive sensor.
3. The transaction terminal of claim 1 ,
wherein the sensor yields an image having a density of at least 500 dots per inch (dpi).
4. The transaction terminal of claim 1 ,
wherein the access control logic does not communicate with the sales transaction processing logic; and
wherein the access control logic includes programmable logic, and the system includes bios instructions to cause the programmable logic to allow access to the cash drawer in response to a determination by the access control logic that a user is authenticated; and
wherein the access control logic comprises a field programmable gate array (FPGA).
5. The transaction terminal of claim 1 ,
wherein the access control logic consists entirely of hardware.
