Embodiment Construction

[0034] A specific embodiment according to the present invention is an operation method applied to a radio frequency identification tag; FIG. 1(A) is a flow chart of the operation method. According to the present invention, before sending various reading and writing requests to the radio frequency identification tag, a radio frequency reading device first sends a radio frequency signal, wherein the radio frequency signal includes an authorization request. In practical applications, the authorization request may include the identification code of the radio frequency reading device itself and / or a set of authorization codes. In addition, the radio frequency identification tag includes a memory block, the memory block stores at least one default authorization code, and the default authorization code is corresponding to the radio frequency reading device.

[0035] As shown in FIG. 1(A), step S11 is to make a radio frequency identification tag receive the radio frequency signal. St...

Abstract

The invention discloses a radio frequency identification tag and an operating method thereof. The radio frequency identification tag comprises a memory block which stores at least one preset authorization code, wherein the preset authorization code corresponds to a radio frequency reading device. The method comprises the following steps: firstly, judging whether the radio frequency reading device is approved by the radio frequency identification tag or not according to the preset authorization code and an authorization request transmitted by the radio frequency reading device; and if the radio frequency reading device is not approved by the radio frequency identification tag, controlling the radio frequency identification tag not to respond to a subsequent request transmitted by the radio frequency reading device. Therefore, the method can assist the radio frequency identification tag to reduce the risk that data is stolen by an illegal radio frequency reading device.

Description

technical field [0001] The invention relates to radio frequency identification technology, in particular to a radio frequency identification tag and an operation method of the radio frequency identification tag. Background technique [0002] Radio Frequency Identification (RFID) technology is a communication technology that uses wireless signals to identify specific targets and read and write related data. Since the data reading system using RFID technology does not need to establish physical or optical contact with a specific target, its data recognition / reading and writing speed is better than that of traditional bar code devices. [0003] In view of the fact that RFID technology can be widely used in logistics management, shopping consumption, identification, smart homes and offices and other fields, and can bring a considerable degree of convenience, many companies have invested huge research and development budgets. However, in addition to the challenge that the cost...
