Overview of RFID Technology

RFID is an acronym for  R adio  F requency  ID entification. It is a technology in which objects can be identified through the tags associated with the object. The information exchange is achieved through radio communication between the RFID tag and the reader. The advantage of RFID system for object detection over barcode or QR system is that it does not need a line of sight interface between the object/tag and the reader.   Image credits - All About Electronics Basic Components in a RFID System: The following fundamental components are present in every RFID system: RFID Tag – It is the fundamental component which is required in a RFID system. Each object is associated with a tag and can be identified amongst other similar other objects using the tag.  A RFID tag consists of a silicon microchip which is attached to a small antenna. It is mounted on a substrate and encapsulated in different materials like plastic or glass veil. It migh...
