New Experience with Payment Terminals in Poland

In cooperation with eService and bezgotówki.pl, we have created a new level of User Experience with Payment Terminals in Poland.

From the beginning...

First of all we have asked users (both sellers and customers, whose using patterns are different) what functionalities of Payment Terminals of different suppliers, they have been encountering issues with.

Below are some of the most recently repeated answers:

Examples of issues, that users encounter while using payment terminals
Users' issues



Then we came up with several UX (User Experience) suggestions to make an ulitimately good experience — for both sellers and customers.
The graph below is showing which suggestions the Users agreed with:

We have also came up with an unusual idea of using Animated SMILEYs just after transaction is done 😁.
To quickly validate the idea — we have rapidly put a clickable prototype to live, to see what the Users would think of it. Then we asked: "Do you think that a SMILEY screen with a goodbye, friendly note could possibly improve the overall Experience?"

A phone mockup that presents exampled SMILEY together with a Pie chart, that illustrates that three-fourths of respondents had a positive attitude towards them.
Respondents have had a possitive attitude towards SMILEYs 😊. I mean — come on — who wouldn't have?



Here are couple SMILEYs presented:

Finally we've managed to tailor the UI layout that responds to the Users needs

Then we have created 3 main UI styles for the Client to choose from:

Based on the first option, that the Client has chosen, we have given 6 viral colour variations to pick the final style from 🤩
