Joining a diversified line of RFID readers, the Intermec IF4 serial reader is the ideal RFID peripheral for applica­tions where an edge server or Program­mable Logic Controller (PLC) is used for process control. The IF4 reduces the com­munications burden on the network and processing demand on the host PLC.

While reading and writing RFID labels and tags, the IF4 uses an air-interface protocol for filtering out unneeded tag data caused by multiple reads and tags not required for the application.

General purpose input/output (I/O) cir­cuitry enables the IF4 to monitor and/or control peripheral devices while keeping the cost of ancillary equipment and instal­lation down.

After the IF4 controls the selection of appropriate tags for reading, it then combines its pre-configured application parameters with the information from the selected tags in order to activate external sensors as well as control audible and visual indicators.
