Disclosed is a system to improve the security of a point of sale station in a retail environment where the scanning and payment transactions take place at two locations. The system incorporates fingerprint scanning through computer-based fingerprint readers. The customer’s fingerprints are associated with the scanned list of items and facilitate a more secure method of order identification at the time of payment.

Secure method for customer identification in separated scan and pay checkout system

In a separated scan and pay checkout system, the customer scans their items at one station, and then goes to another station in the store to pay for the transaction. In the past, the pay station has been physically co-located with the scanning equipment, and there was a 1-1 correspondence between the scan station and the pay station.

Current thinking in the industry is for high-volume retailers to install high speed scanners in one location to identify a customer's items, and have another location where the customer pays for the items.

In the typical scenario today, the customer receives a small receipt at the scanning station that identifies their order and stores the information in the transaction in the system; this receipt is used at the second station to complete the payment process.

For the convenience of the customer and to maintain security, the method is improved with the removal of the paper receipt.

The proposed invention is to add a fingerprint scanner to both the scan and payment stations. At the start of the scanning process, the system requests the customer to allow their fingerprint to be scanned. When the customer moves to payment station, their finger is again scanned. The system identifies the transaction as belonging to the customer via the stored fingerprint that is associated with the transaction.
