Abstract
Embodiments relate to a tag device, a reader device, and a radio frequency identification (RFID) system. The Q embodiment provides a tag device comprising: a reception module converting a received high frequency signal into a scale level, and Q converting the converted scale level into a digital signal to output the same; a transmission module modulating a transmission signal M to output the same; and a controller controlling the reception module and the transmission module. The tag device communicates o with the reader device through wireless short distance communication.
Claims20
A tag device comprising:
- a reception module converting a received high frequency signal into a scale level, and converting the converted scale level into a digital signal to output the same;
- a transmission module modulating a transmission signal to output the same;
- and
- a controller controlling the reception module and the transmission module.
A reader device comprising:
- a reception module converting a received high frequency signal into a scale level, and outputting the converted scale level reception signal as a digital signal;
- a transmission module modulating an information request signal to output the same;
- and
- a controller controlling the reception module and the transmission module.
A radio frequency identification system comprising:
- a tag device comprising:
- a first reception module converting a received high frequency signal into a scale level, and outputting the converted scale level reception signal as a digital signal;
- a first transmission module modulating an information request signal to output the same;
- and
- a first controller controlling the first reception module and the first transmission module, and
- a reader device comprising:
- a second reception module converting a high frequency signal received from the tag device into a scale level, and outputting the converted scale level reception signal as a digital signal;
- a second transmission module modulating an information request signal, and transmitting the signal to the tag device;
- and
- a second controller controlling the second reception module and the second transmission module.
