RFID Primer

"Radio Frequency Identification is a technology that has been around since 1920. It is a technology that is delivered by means of small microchips called “tags.” These small objects have an adhesive sticker attached to or incorporated into the product. RFID tags use antennas which are used to receive and respond to frequency emitted by RFID transceivers. Radio frequency uses the method of remotely storing and retrieving data using RFID tags or transponders. These tags can be read by electronic scanners." Source: expresscomputeronline.com
