When our President Hideyuki Nebiya has worked at Hitachi Shonan Denshi, he started to develop the "Transponder System for Factory Automation / Production Line" as a developing team leader in 1984. At that time, we did not name it "RFID", but it was the same system as the recent Passive RFID System lately. So AMPLET Communication Laboratory is very good at designing RFID System. Our President, Hideyuki Nebiya has been writing many RFID technical books and articles in magazines.
The RFID (Radio Frequency IDentification) puts on an object for the purposes of reading the ID (IDentification) and tracking by using radio wave. The RFID can be read from several meters away from the reader.
