Customer Display Screen (CDS) App

This CDS app allows you to display basket information and promo banners to your customers. To use, the application must be configured in the SumUp POS back-office under Register setup. When logged into the app, please go to the SumUp POS app in the appropriate register and select the Connect Display button from the list of options.


To install the application, visit the Amazon Appstore, search for Goodtill CDS and follow the instructions. (compatible with android 5.0 and later)


Insert store subdomain and Register Number in the appropriate fields and hit the Load Display button. Ensure the appropriate details are inserted for its corresponding till (e.g. Demo125 / 0001)

Display Screen

Upon load, the display screen is synced with the order details from its corresponding till. This would further reflect the order items, discount/service charge, total, due, served by personnel, and a promo banner that can be replaced on the Back office in the register settings (Setup > Register)

Please note that modifiers will not show on the display screen


In a situation where you wish to change the connected till; the user is to hold the ‘Served by’ detail at the bottom left corner (shown below), for 7 seconds and select the Confirm button on prompt. This would delete the current register details, remove the application’s immersion, and request a new entry.
