Detailed explanation-1: -RFID RFID (radio frequency identification) is a standard, specifically a protocol, that defines how a network uses radio signals to communicate with a tag placed in or attached to an object, an animal, or a person.
Detailed explanation-2: -The current standard used in RFID is the EPCglobal Class 1 Gen 2 protocol (EPC C1G2) [13]. This is an arbitration oriented protocol used in every commercial reader, also included in ISO 18000-6C.
Detailed explanation-3: -The RFID reader is a network-connected device that can be portable or permanently attached. It uses radio waves to transmit signals that activate the tag. Once activated, the tag sends a wave back to the antenna, where it is translated into data. The transponder is in the RFID tag itself.
Detailed explanation-4: -RFID is a technology that uses radio waves to transfer data from an electronic tag, called an RFID tag or label, through a reader attached to an object for the purpose of identifying and tracking the object.
Detailed explanation-5: -RFID tags are affixed to items in order to track them using an RFID reader and antenna. RFID tags transmit data about an item through radio waves to the antenna/reader combination.
