9.1 Describe the installation and configuration of an RFID printer (may use scenarios)
9.2 Describe ancillary devices/concepts
If you think of bubble gum, baseball caps, or batting gloves, you're thinking of peripherals for a baseball player. Radio frequency identification (RFID) systems are no different-the tags, readers, and antennas are the main aspects of RFID, just as the bats, mitts, and baseballs are the equipment of baseball. But just as the game isn't a game without its peripherals, an RFID network isn't an RFID network without peripherals, either.
RFID peripherals are devices that provide the RFID system with the capability to encode and verify tags, trigger interrogation, or react to various events created by data that are generated by the interrogation zones. Some readers/interrogators have evolved into "smart" machines like sophisticated computers; their capabilities have grown not only to filter, process, and store data coming from RFID reads, but also to directly manage most of the peripheral devices through input/output (I/O) ports.
RFID peripherals include RFID printers/encoders that encode the RFID tag with data and print visible information on the label; label applicators that apply labels to products; diverters, which are used mainly with conveyors for routing products to various destinations; triggering devices such as motion sensors or infrared sensors; and feedback devices such as light stacks, alarms, diverters, and other devices that might be part of an RFID network.
In this chapter, you'll learn about the following:
The function, installation, and configuration of an RFID printer/encoder
The function and working principles of different kinds of label applicators
The working principles and reasons for using triggering devices
The working principles and reasons for using feedback systems
The concept of real-time locating systems (RTLS)
