Every RFID implementation needs peripheral devices such as RFID-enabled
printers, RFID-enabled automated label applicators (also known as print and
apply devices), as well as feedback components such as light stacks, horns, LED
lights or LCD displays, and triggering devices such as light break sensors. These
devices enhance the capabilities of an RFID system, control I/O devices, control
system timing functions, and provide on/off capabilities for various business
applications. Peripherals also improve human interactions with RFID hardware
by assisting automatic data collection and increasing the safety of the system.
