Radio Frequency Identification (RFID)

* It is a data collection system based on tiny micro-chips attached to a box, pallet or an individual item that communicates with other devices using radio waves. Device readers capture the data from tags and, in some cases, write to them as well. The software then collates and distributes the data.
* It is nowadays used mostly in retail, asset tracking and logistics fields.
*An RFID tag is a small object, such as an adhesive sticker, that can be attached to or incorporated into a product. RFID tags contain antennas to enable them to receive and respond to radio-frequency queries from an RFID transceiver.
