STEP 1: Associate a Model ID with a SKU
- Go to https://data.smartcircle.net/ and log in using your account
 - Select Devices from the menu on the left
 - Choose the device that you want to associate with a SKU

 - In the form on the right hand side of the page fill in the SKU and Save the changes
 - You can enter multiple SKUs, separated by  |  (pipe symbol)

 - Once you have completed above steps you will see the SKU during enrollment process of the Display app on an Android device
 
STEP 2: Enrolling device matching proper SKU (EAN/UPC)
You must have the Enrollment code for the location and the SKU number for each device before you proceed!
- Open the SmartCircle Display app and click on the Enroll this device button.

* Above process can be repeated at any time if you find the wrong price or you want to change it intentionally.
STEP 3: Import a new price list that includes as many SKU (EAN/UPC) for the same model ID as there are options
Import the prices on your Price Tag Management portal
- Make sure to have two records for the same model
 - The new phone will have a Model ID and no SKU
 - The refurbished phone will have a Model ID and SKU.
