Mobile radio frequency identification reader, portable terminal having the same, and FR transmission power setting method thereof

摘要

A mobile radio frequency identification (RFID) reader, a portable terminal having the same, and an RF transmission (Tx) power setting method thereof. The RF Tx power setting method includes selecting an RF Tx power of an RF Tx power which is used to read tag information from an RF identification (RFID) tag; and setting the selected RF Tx power to a Tx power of the RF Tx signal. Accordingly, since it is possible to variably set the Tx power of the RF Tx signal used to read out the tag information from the RFID tag, the power consumption can be reduced at the RFID reader or the portable terminal equipped with the RFID reader.
