RFID

Radio Frequency IDentification- is a special kind of wireless communication to identify or count an object contactless. On one side you have a RFID-reader, like a terminal or handheld device. On the other side you have a transponder, like a tag or a label.

In a passive RFID system, the reader sends out a field of energy and data. The transponder uses the energy and data to read out his memory and sends the content back to the reader. At an Active-RFID system the transponder has its own battery, which allows much bigger memory sizes, a wider range and a faster communication.
