US Patent 9286560 Creation and management of dynamic quick response (QR) codes

A quick response (QR) code change event configured to cause a processor to change encoding of a displayed dynamic QR code is detected. The dynamic QR code includes an encoded unique value associated with an item displayed in a retail environment. Encoding of the dynamic QR code is changed to encode a new unique value. The new unique value is based upon a set of contemporaneous data elements associated with the item displayed in the retail environment. The changed dynamic QR code including the encoded new unique value is displayed in association with the item displayed in the retail environment.
