A barcode rendering device, comprising:
- a communication interface configured to receive barcode data corresponding to a barcode in one of a plurality of barcode symbologies;
- a reflective display configured to legitimately display barcodes in any of the plurality of barcode symbologies;
- and
- a detector configured to detect illumination emitted by a barcode scanner and incident on the reflective display.
A method for redeeming a printed barcode, comprising:
- determining barcode data of a printed barcode;
- communicating, to a clearinghouse including a database storing barcode data of a plurality of barcodes, barcode data of the printed barcode and a unique identifier associated with a particular user or a particular device;
- receiving new barcode data corresponding to a new barcode, the new barcode data including the barcode data of the printed barcode and a unique signature associated with the particular user or particular device;
- and
- causing the new barcode to be displayed on a reflective display for scanning by a barcode reader.
A method of validating a scan of a barcode displayed on a barcode rendering device, the method comprising:
- displaying a barcode on a display of the barcode rendering device;
- detecting a first signal indicating an attempted scan of the displayed barcode by a barcode scanner;
- detecting a second signal indicating acceptance of the attempted scan by a point of sale terminal to which the barcode scanner is communicatively coupled;
- and
- based on the detection of the first and second signals, determining that the attempted scan of the displayed barcode by the barcode scanner was successful.
