What is the difference between a reader, a writer (encoder) and a transceiving antenna?
Readers, writers are encoders, for RFID purposes, are the same device. Readers are typically built with a memory configuration which contains the firmware (“smarts”) of the reader. When connected to a computer, software can be used to communicated with the reader A transceiving antenna is typically not much more that a copper loop encased in plastic. The copper is “tuned” to the frequency at which it is intended to operate. Electronic leads from the antenna are connected to a reader. Radio signals are then passed from the transceiving antenna to the transponders (tag).
