RFID employs Radio Frequency Communications to exchange data between a portable memory device and a host computer or PLC. An RFID system typically consists of a "Tag/Label/PCB" containing data storage, an Antenna to communicate with the Tag, and a Controller to manage the communication between the Antenna and the PC or PLC (the terms Reader or Reader/Writer are used when the Antenna and Controller are combined in one housing).
Importantly, the Tag/Label/PCB is commonly attached to a product carrier, tote or even the product itself, providing a remote database that travels with the product.
