What is RFID?
RFID, or Radio-Frequency Identification, is a technology that employs radio waves to identify and monitor objects, animals, or people wirelessly. It functions similarly to a digital barcode, allowing for reading from a distance without requiring direct contact or a clear line of sight. An RFID tag is composed of two essential components: a microchip and an antenna, both encased within a durable shell designed to shield them from external environmental factors.
How RFID Works?
An RFID system generally consists of a reader, a transceiver, an antenna, and a transponder, often referred to as an RFID chip, label, or tag. The reader continuously emits a signal, and when a compatible tag comes within its range, the tag captures the signal and transmits the requested information back to the reader.
Active tags have an internal battery that enables them to send data over greater distances, usually up to 100 meters, and allows them to store new information. In contrast, passive tags do not have a battery, which limits their capabilities: these tags are powered by the radio waves from the reader, which restricts their range and data transmission abilities.
