METHOD AND SYSTEM FOR CONTROLLING PROXIMITY TRANSACTION

摘要

PROBLEM TO BE SOLVED: To provide an improved method and a system for controlling the proximity transaction using a near range communication unit. SOLUTION: A first communication unit P1 comprises an RF/ID reader 5, and a second communication unit M1 comprises an RF/ID tag 6 including the same identifier information as the second unit M1 located within an accessible range of the reader 5 in the first communication unit P1. A transceiver 1 of the second communication unit M1 sends a transaction request and identifier information of the communication unit M1 to the first unit P1. The reader 5 of the first unit P1 calls the tag of the second communication unit M1, and ends transaction at a point when receiving the same identifier information from the tag of the second communication unit M1 as that already received by the reader 5 of the first unit P1.
