The handheld scanner and the Scan n Go app will not pick up any unusual barcodes.
The barcodes that are:
* sale barcodes (reduced price barcodes)
Note: if you can remove the reduced price barcode, you can scan the original barcode, that may be underneath.
* some foreign barcodes where the barcode is too long or short.
* Some clothing/ hardware barcodes
* Glossy barcodes, such as frozen food. You will need to wipe any water residue on it.
If you can not scan those items, please leave them out and move on to scanning other items.
Please see the below article on which barcode to scan:
Please make sure that your camera is clean on your device if you are using the Scan n Go app. For the handheld scanner, make sure the top screen is clean.
You need to be in a well-lit area for your scanning device to pick up the barcodes.
