METHOD AND APPARATUS FOR IDENTIFYING AN RFID TAG

摘要

An object of the present invention is providing a method and apparatus for identifying an RFID tag. A first card reading device sends to an identification serving means an identification request for identifying an RFID tag, and receives a response message sent by said identification serving means in response to said identification request. Compared to the prior art, the present invention accomplishes identification of an RFID tag by using the communication between the card reading devices, the communication between the card reading devices and control devices and/or the communication between the control devices, thereby a large scale of RFID tag deployment becomes possible. Furthermore, the way of grading the communication targets of the card reading devices makes most of the RFID tags accomplish the privacy identification procedure between the card reading means within the same group, thereby avoiding the identification requests of all RFID tags to be sent to the centralized mainframes, and hence reducing the requirement for the centralized mainframes and the risk of failure occurrence.
