How RFID Works
A basic RFID system consist of three
components that include, an antenna or coil, a decoder or reader
(transceiver), and a tag (transponder) electronically programmed
with unique information. To initiate the communication of
information, the antenna emits radio signals which activate the
tag. This allows data to be written to and read from the tag. The
antenna acts as a conduit between the tag and the transceiver,
which controls the system’s data acquisition and communication.
The antenna emits radio signals to activate the tag and read and
write data to it.
