About RFID

Radio Frequency IDentification is a method of storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is a small object, such as an adhesive sticker, that can be attached to or incorporated into an object. RFID tags contain antennas to enable them to receive and respond to radio-frequency queries from another RFID transceiver. Passive RFID tags require no internal power source, as they receive their power from the interogating transceiver, which is usually contained with a handheld device or label printer. In addition I/O devices, light barriers, light stacks, PLCs, barcode readers are often required in addition in total solutions.
