Velocity

Cross-border transfers with every fee shown before the confirm button.

A speculative case study - real design work, no client, no completed user testing.

Caveat
Run 1 hits a cold CDN cache, so it is the slowest. On a simulated slow phone the same sites score between 67 and 77.
Stated
Numbers without runs come from the project record, not from a measuring tool.

01Problem

Cross-border banking hides its fees, holds transfers for days and treats the sender like a suspect.

  1. Goal 01Show the exact cost before confirmation.
  2. Goal 02Explain every financial term in plain language.

02What was built

  1. 01

    SEPA Instant speed

    Money arrives in seconds through SEPA Instant, instead of after 1-3 business days.

  2. 02

    Fees before confirm

    The exact cost is on screen before the confirm button.

  3. 03

    Plain-language finance

    Fees and terms are written in plain words, with nothing left to the fine print.

03Process

  1. 01

    Trust research

    Fee clarity framed as the main trust driver for people who send money across borders.

  2. 02

    Honest structure

    Compliance checks are explained as protection for the sender, in plain language.

  3. 03

    Precision design

    White space lowers the load of a money decision, and every element on screen has a job.

  4. 04

    Fast prototype

    Built as a working prototype in 48 hours.

04Principles

05Lesson

Financial products often hide behind complexity. Velocity argues that clarity and white space can turn a transaction into something people trust.
