Abstract

The invention relates to an RFID (Radio Frequency Identification) read-write device and particularly relates to a mobile phone card with an RFID reader chip, wherein the mobile phone card combines with the RFID read-write device and a mobile communication device. The mobile phone card with the RFID reader chip comprises an SIM (Subscriber Identity Module) card on which an SIM card microprocessor chip, an ultrahigh frequency RFID reader chip and an antenna are integrated, wherein the ultrahigh frequency RFID reader chip is connected with the SIM microprocessor chip, and the ultrahigh frequency RFID reader chip comprises the RFID reader chip, a power amplifier, a coupler and an active crystal oscillator; the RFID reader chip is connected with the coupler through the power amplifier, and the coupler is further connected with the antenna; and the RFID reader chip is further connected with the active crystal oscillator. By utilizing the mobile phone card with the RFID reader chip on a mobile phone, the normal mobile phone has a function of reading and writing an RFID electronic label; and the mobile phone with the mobile phone card has the advantages of longer reading distance and higher data transmission speed while reading and writing the label.

Description

technical field [0001] The invention relates to an RFID read-write device, in particular to a mobile phone card with an RFID reader-writer chip in which the RFID read-write device is combined with a mobile communication device. Background technique [0002] There are many anti-counterfeiting technical solutions on the market, such as laser anti-counterfeiting, ink anti-counterfeiting, digital phone anti-counterfeiting and mobile phone SMS anti-counterfeiting. Studies in recent years have shown that the anti-counterfeiting scheme using RFID electronic tags is a very effective high-tech anti-counterfeiting means. The main content of RFID electronic tag anti-counterfeiting is to affix an RFID electronic tag to the item, which stores the unique identification code of each product, unencrypted product-related information or encrypted anti-counterfeiting certification information. The special reader can obtain the data of the electronic tag by exchanging data with the electronic...
