<p><P>PROBLEM TO BE SOLVED: To provide a two-system card common reader/writer and a two-system card management system that uses the same. <P>SOLUTION: The two system card common reader/writer is configured to transmit/receive data in a non-contact state between first and second system cards, each having a card storage part for transmitting/receiving data by first and second modulation systems, respectively and for storing an electronic money charge amount. The two system card common reader/writer is provided with a first system polling means; a second system polling means; a means for trying data transmission/reception by the first and second system polling means to the card, and for determining whether the card is the first system or the second system by detecting a response signal; a means for preliminarily storing items and prices, in association with each other in the storage part; a means for accepting the input of the designation of purchase items, and for acquiring the prices of the designated items from the storage part; and a means for controlling the data transmission/reception to each system card by each modulation system so that the electronic money charge amount of the card storage part can be rewritten. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
