Abstract: An RFID reader, RFID tag, and method thereof for performing a write check of tag data. According to an exemplary embodiment, the RFID reader may include: a transmitter to transmit a write check command to an RFID tag; a receiver to receive a response including a check value of data, which needs a write check, from an RFID tag that has received the write check command; and a controller to perform information transmission and reception processes, and check data written on the RFID tag by using the received response.

Abstract: Disclosed are an apparatus and a method for transmitting a tag. The apparatus for transmitting a tag converts 2 bits of a plurality of bit data into one symbol using phase information and orthogonal information. The apparatus for transmitting a tag generates a sub-carrier signal by multiplying the symbol by a square wave having a faster period by a predetermined number of times than a period of the symbol, and transmits the sub-carrier signal to a reader
