Title:
無線周波数識別タグが組み込まれた移動端末回路及びその移動端末機での無線識別方法
Document Type and Number:
Japanese Patent JP4022532
Kind Code:
B2
Abstract:
A mobile terminal circuit for transmitting radio frequency identification (RFID) data to an RFID reader. The mobile terminal circuit comprises an antenna (200) for communication with the RFID reader; a memory portion (102) for storing RFID data together with mobile terminal protocol data; a codec (404) for encoding the RFID data into RFID codec data; a modulator (405) connected to the codec, for modulating the RFID codec data into RFID modulation data; a processor (305) connected to the memory portion, for extracting RFID data stored in the memory portion and delivering the extracted RFID data to the codec; a detector (304) connected to the antenna and the processor, for informing the processor of approach of the RFID reader; a first clock generator (250) connected to the processor and the memory portion, for providing operation timing to the processor and the memory portion; and a second clock generator (302) connected to the first clock generator, the codec and the modulator, for providing operation timing to the codec and the modulator.
