The Notifier Attribute will allow you to populate a message in the attribute field which will be displayed in a pop-up window on the screen when the SKU is added to a transaction in the POS screen.
First, go to the Attribute tab in the Setup of the AmberPOS software. Please see the article Adding New Attributes.
Step 1: Select to create a Sku attribute.
Step 2: Name the attribute "Notifier" without quotations.
Step 3: Choose the Attribute format "Text"
Step 4: Click "Add New Attribute" to create the attribute.
After you have created this attribute, you will want to go to the SKU which you want to enter a message for, and populate that message in the attribute field for that SKU. Be sure to Save the SKU before navigating to another part of the software.
You will now see that when you add this SKU for a transaction that the message you entered will appear in a pop-up window in the bottom right-hand corner of the screen.
