When you have a new POS device, it needs to be linked in order to begin using LOU Retail POS and process transactions. Most of the time, you will take care of this during Onboarding, but the process is the same if you add additional POS device after go-live.
REMEMBER! Before you begin, you will need the Serial Numbers for each of your POS devices. These can be located on the box or on the machine. On a barcode, you will see “S/N” followed by a 10-digit number. This is the Serial Number.

· PAX Serial Number is where you’ll enter that Serial Number you located on the barcode of the box or machine.
