Self-service terminals are the most critical friction point in the user journey. A person stands outside — often in uncomfortable conditions — and needs to pay and start the wash as quickly as possible. The old interface created unnecessary steps, visual noise, and unclear selection scenarios, directly increasing transaction time and the number of abandoned sessions.
We rebuilt the entire user scenario from the moment of arrival to the start of the wash. We eliminated redundant screens, restructured the element hierarchy, and simplified the selection logic. The interface now operates on a single principle: one action — one screen.
- The path from program selection to payment was reduced from 6 steps to 2
- All touch zones were adapted for use with gloves and in direct sunlight
- A quick repeat scenario was added for returning customers — one tap instead of the full flow
- Competing CTAs were removed — every screen has a single target action
Payment speed increased 2.6x. Abandoned sessions dropped by three times.
The interface stopped being a barrier — and became part of the service.
