Abstract

The invention relates to a mobile telephone with the read-write function of electronic label, comprising: the mobile telephone, wherein the signal input terminal of RFID read-in device is connected with the signal terminal of radio-frequency switch in the mobile telephone, the signal output terminal of RFID read-in device is connected with the signal terminal of microprocessor in the mobile telephone. The invention has the advantages that the read and communication to the tour guide information by the mobile telephone are realized conveniently; the manufacturing cost is low, any manufacturer of mobile telephone can make the same without the limit of operators and with wide adaptability.

Description

technical field [0001] The invention relates to a mobile phone with the function of reading and writing electronic tags, which belongs to the field of mobile phone manufacturing. Background technique [0002] In the patent application of 200510086704.6, a technical solution was proposed to organically combine the special reading and writing equipment of the electronic tag (RFID: Radio Frequency Identification) with the mobile communication device (mobile phone), and the technical solution invented was the card body of the SIM card An RFID reader-writer chip capable of reading and writing RFID electronic tags and an external antenna connected to the RFID reader-writer chip are also arranged on the top, and the RFID read-write chip is connected to the SIM card IC chip. The existing problems are: First, the SIM card is generally placed under the battery and on the PCB board, so the reception effect of the antenna installed on the SIM card is extremely poor, which is similar to ...
