Abstract
A radio frequency identification (RFID) tag capable of improving convenience of a user and a method of driving the RFID tag are provided. The RFID tag includes a displaying unit displaying tag data indicating a current state of the RFID tag. The displaying unit displays the tag data even when the RFID tag does not exist in a read range of the RFID reader. Thus, a user can recognize the current state of the RFID tag without using the RFID reader.
Claims14
An RFID (radio frequency identification) tag comprising:
- a tag antenna which receives an input power and input data from an RFID reader and which transmits ID (identification) information corresponding to the input power to the RFID reader;
- a tag driving unit which provides the ID information to the tag antenna and which updates and stores tag data which indicates a current state of the RFID tag using the input data;
- and
- a displaying unit driven using the input power received through the tag driving unit and which displays an image corresponding to the tag data.
A method of driving an RFID (radio frequency identification) tag, comprising:
- receiving an input power from an RFID reader;
- detecting ID information corresponding to the input power and transmitting the ID information to the RFID reader;
- and
- receiving input data from the RFID reader to update and display tag data.
An RFID (radio frequency identification) tag comprising:
- a tag antenna which receives input power and input data from an RFID reader;
- and
- a display unit which displays tag data based on the input data received from the RFID reader;
- wherein the displayed tag data remains the same until a new input data is received from the RFID reader.
