What is RFID?

RFID stands for Radio Frequency Identification. It is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. RFID tags contain electronically stored information that can be read by a reader device without physical contact.

How does RFID work?

RFID systems consist of three components

1. RFID Tag/Transponder: Contains a microchip and antenna, storing information.
2. RFID Reader/Transceiver: Emits radio waves and receives signals back from the RFID tag.
3. Antenna: Allows the tag and reader to communicate.

When the RFID tag comes within range of the reader's electromagnetic field, it transmits the stored information to the reader.
