Items not scanning properly

If you are unable to scan an item, verify the following:

Verify the bar code was entered correctly in Back Office. This includes entering all numbers on the bar code, including the leading check digit, manufacturer and item code, and trailing check digit in one string. (i.e. 123456789012).

Note: The bar code scanner used for the POS can read 1-D bar codes, which are made up of alphanumeric characters only. If you are having difficulty entering the bar codes for your items, you can use the POS app to dynamically scan the bar code for your item and enter the item details directly into the POS app. On the next data sync, the POS app will push the new bar code to Back Office.
Verify the item has been downloaded from Back Office to the POS.
Log in to the POS.
Tap the hamburger menu icon on the left to display the slide out menu.
Tap the System tab.
Tap Data Sync.
Select one of the following Data Sync options:
- Refresh — Only syncs changes that have been done in the past 6 minutes.
- Partial Data Sync — Only syncs items, customers, or configurations that have been changed in the past three days.
- Full Data Sync — Deletes local copies and re-downloads all data.
If you selected Partial Data Sync, tap Yes in the confirmation message.
If you selected Full Data Sync, tap Yes.
Wait for the sync process to complete and tap Close. Depending on your selection, the process can take from a few seconds to 30 minutes.

Bar code scanning issues

When the scanner is properly set up with device and item is set up in Back Office but is not reading on the POS, i.e. if the customer scanner is not reading custom bar code labels, verify the following:

With the Dymo software, the socket CHS Mobile Scanner, and Silver software there are various restrictions when it comes to alphanumeric barcodes. It is highly recommended to advise the customer to use only numeric barcodes because of these restrictions. However, there are customers that will insist on using alphanumeric barcodes. These barcodes will only be accepted and scanned in the following formats:

Code 39
Code 128 Auto
Code 128 Type A
Code 128 Type B
Code 128 Type EAN

Note: If the customer ever sees 'Try to increase width' in the Dymo software, this means the bar code data is too large for the type of label/template being used. To fix this either decrease the barcode length (remove numbers or characters from barcode) or choose a larger label/template.
