This work covers the ongoing design of Zimpler’s payment interfaces, including deposits, withdrawals, account selection, and identification flows. Over time, these flows have grown in scope and complexity as new use cases, markets, and requirements were added.

The work focused on making these interactions easier to understand and safer to use, even as the underlying logic became more advanced. Through many iterations, the goal was to bring structure and consistency to how payments behave and feel, so users can move through critical steps with confidence and as little friction as possible.
