Use the following procedure to configure application filtering and data extraction properties for barcode devices using a
UPC/EAN format.
1. Set any or all of the To Application Filter Options (RFID/Barcode) filtering options.

2. If you are using standard twelve to fourteen‐digit UPC/EAN barcodes, set the Barcode UPC/EAN 12-14 Digit Format
