What is how do rfids work?

RFID (Radio Frequency Identification) technology works by using electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information that can be detected and read by RFID readers using radio frequencies.

There are two types of RFID tags: active and passive. Active tags have a power source and can transmit information over long distances while passive tags do not have a power source and rely on the energy from the RFID reader to transmit information over short distances.

RFID tags are used in a variety of applications such as tracking products in warehouses, managing inventory in retail stores, monitoring livestock, and tracking luggage in airports. The technology is also used for access control systems, vehicle tracking, and even in automated toll booths on highways.

Overall, RFID technology provides a convenient and efficient way to track and manage assets without the need for manual input or scanning of barcodes.
