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

摘要

non-contact communication means (3a) for reading a card identifier ID stored in a memory of an IC card; a barcode generation unit (22) for generating a two-dimensional code of bonus data correlated to the card identifier ID read by the non-contact communication means (3a); and a display unit (13) for displaying the bonus data generated by the barcode generation unit (22) in a two-dimensional code. The bonus data displayed in the two-dimensional code displayed on a display unit (13) can be read by a barcode reader (2a) of a POS terminal (2). Thus, when applying bonus data such as an electronic coupon to a POS system, it is possible to minimize the modification of the POS system.
