That's how self-checkout machines in libraries work: they beam radio waves into the RFID tag in the back of the book, receive the radio signal back from the book, and decode this to figure out a digital code that uniquely identifies which book you want to check out.

The RFID tags in the field receive the energy, or RF waves, using their own antennas. The energy received travels through the RFID tag's antenna and a portion of it is used to activate the chip (i.e. the Integrated Circuit, or IC) and prepare for transmission of data based on commands received from the RFID reader. RFID readers serve as vital components in the RFID system. These devices play an active role in managing communication with RFID tags. When we initiate commands, the readers generate an RF carrier wave, which we continuously monitor for modulation indications. Detecting such modulation alerts us to the presence of RFID tags.How RFID Tags Work. The working principle of RFID tags is based on the propagation of radio waves. Here are the detailed steps of how they operate: Data Storage: The microchip inside the RFID tag stores the tag’s unique identifier and any additional data. This data is transmitted during communication between the tag and the reader.An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader.

A passive RFID tag receives its power from the reading antenna, whose electromagnetic wave induces a current in the RFID tag's antenna. There are also semi-passive RFID tags, meaning a battery runs the circuitry while communication is powered by the RFID reader.Water and metal respectively absorb and reflect the radio wave and significantly reduce the effectiveness of RFID systems. As far back as 1830, Faraday discovered that high-frequency radio waves were absorbed by metals.

RFID labels, capable of storing substantial information, utilize radio waves for communication, eliminating line-of-sight requirements and enabling remote scanning. Originating from the radar technology of the 1940s, commercial applications of RFID .RFID is an acronym for “radio-frequency identification” and refers to a technology whereby digital data encoded in RFID tags or transponders is captured by a reader via radio waves. RFID is similar to barcoding in that it provides a way to digitally store and retrieve information. That's how self-checkout machines in libraries work: they beam radio waves into the RFID tag in the back of the book, receive the radio signal back from the book, and decode this to figure out a digital code that uniquely identifies which book you want to check out.
