The car washes handheld POS
One of the biggest project I’ve been working on for the car wash industry.
Nine months of fascinating and hard work.
Weeks of research, 480 hours of design and 300+ screens.
Working hand in hand with the Android developers
for more than 6 months. 2 months of testing
and debugging and finally release on PAX STORE.

COVID-19 Impact
The pandemic ushered in several significant improvements in the industry. To make it easier for consumers, car washes have begun to use handhheld devices, smartphone apps and online booking systems.
Problem
POS Terminal
Outdated cloud-based point-of-sale solution for car wash business owners with cash register, magnetic stripe card reader and EMV Chip reader and printer and those are all separate devices.

PLANS
Business Goals
increase profit margin
- Increase sales revenue;
- Make the terminal cheaper for retail;
- Reduce transportation logistics costs.
Customer Goals
increase car wash revenue
- Serve more customers;
- Reduce employee onboarding time;
- Use stable handheld device with internet.
Target Audience
Car wash owners and their staff (managers and attendants).
There were a few things I had to keep in mind:
-
Some tunnel and in-bay car washes have up to 1000 vehicles a day, so the employees can be in real rush;
-
The elements on the screen have to be a bit bigger, so car wash employees can easily tap on any element when they are in rush;
-
Car wash workers can take the device outside (light and dark themes);
-
And of course, the interface have to be clean, intuitive and user-friendly.
Challenges
Migrate the POS Terminal to Android OS without changing a single line of code in database and APIs
Create seamless onboarding experience

Mind Map & Wireframe
This stage took me around a month alongside with the low fidelity prototype and first testing.
High Fidelity Mockups
At first we were planning to use PAX E600 only, so I started from the vertical layout for the 8-inch 800x1280px screen.
Later on, top management decided to add one more device and that’s where landscape layout started.
3 months
It took me 3 months from the
very first block on a mind map
to the finalized prototype
300+ screens
More than three hundred
screens have been designed
for the portrait and landscape
