Review the filtering. Category, Vendor, Product Code, or HCPCS code can filter items. Change or set to scan only RFID-enabled Products, or Barcode only, as well as for products that are manufacturer-serialized. **Be careful!** Products must meet all the criteria selected. If RFID only and Barcode only are selected, nothing would show up, as they are mutually exclusive. The toggle beside the filters must be blue to be selected.
