To register a customer in a transaction at the checkout, as a contact, the customer must be assigned to a transaction manually via the search function at the checkout, or alternatively via a scan process.
For this purpose, 60086 is prefixed to the customer number barcode as a standard. Our customer number in the standard is created in the format 100001, which means that the minimum length for such a barcode is 11 characters. The used scan code can be a barcode or a QR code.
As an example, here is a Code 39 barcode and a QR code.
An adjustment to this is possible in the higher business plans from "BusinessPlus".
