DISPLAY DEVICE, DATA PROCESSING METHOD AND DATA PROCESSING SYSTEM USING THE DISPLAY DEVICE

摘要

The present invention has non-contact communication means (3a) configured to read a card identifier ID stored in a memory of an IC card, a barcode generation unit (22) configured to generate a two-dimensional barcode of a bonus data associated with the card identifier ID read by the non-contact communication means (3a), and a display unit (13) configured to display the two-dimensional barcode of the bonus data generated by the barcode generation unit (22). And, the bonus data displayed on a display unit 13 in the two-dimensional barcode is read by a barcode reader (2a) of a POS terminal (2).
