近接トランザクションを制御する方法およびシステム
Document Type and Number:
Japanese Patent JP4090808
Kind Code:
B2
Abstract:
A method is disclosed of controlling a proximity transaction between first and second communications devices (P1 and M1), each of which is provided with a short-range transceiver (3, 1). The first communications device (P1) has an RF/ID reader (5), and the second communications device (M1) has an RF/ID tag (6), the RF/ID tag containing the same identifier information as the second communications device. The second communications device (M1) is positioned within the range of the reader (5) of the first communications device (P1). Then, the transceiver (1) of the second communications device (M1) transmits a transaction request and the identifier information of that device to the first communications device (P1). The reader (5) of the first communications device (P1) then interrogates the tag (6) of the second communications device (M1), and the transaction is completed upon the reader (5) of the first communications device (P1) receiving identifier information from the tag (6) of the second communications device (M1) that is identical to the identifier information already received.
