On supported dual-screen terminals, such as the Sunmi T3 Pro, Viva automatically adapts the PIN entry process to ensure secure input and proper display behavior.
This behavior ensures a consistent and secure payment experience on dual-screen terminals while preserving customer privacy during PIN entry.
Behaviour
When running on a dual-screen device configured in screen-mirroring mode, Viva displays the PIN entry interface on both screens.
The customer screen remains fully interactive, allowing PIN entry.
The merchant screen mirrors the interface but does not display keypresses or entered digits, maintaining PIN confidentiality.
Supported Devices
Sunmi T3 Pro
Other Android dual-screen devices operating in mirrored display mode
