The Problem

Travellers who need to exchange their currency often find it difficult to search for currency exchange providers near to their location who would offer a good rate of exchange and other facilities like doorstep currency delivery, Zero transaction fee offer, etc. Even if a traveler searches on search engines he may miss out on certain good deals which he did not get in his search result or aware of.


Reduce the effort and time taken by a traveler to figure out the best currency rates offered in the market for exchange.

The Solution

Design a product through which collates all the exchange providers and help travellers quickly compare the best currency rates by different exchange providers and the facilities they provide.

User Persona

I conducted several user interviews to understand their needs and pain points, most of them had pretty similar experiences. Based on my interviews I had defined the following persona.


User Journey

Vinay’s journey for finding best rates for currency exchange.

Note: Users also have to go through several websites and which means they also have to go through several website experiences. This leads to more frustration in the user eventually.

Initial Design Brainstorming

This process was performed to ideate and quickly move to the most appropriate and logical direction.

Define scope


  • The purchase of currency.
  • Offers by the exchange providers.
  • Best exchange rates and comparison of the facilities they provide.

Not Handling

  • There can be a case to send money to someone in other countries.
  • Sort and Filter can be added to the exchange providers’ results screen.
  • Integration with exchange providers can also be done in a way that users don’t have to visit their website and make the purchase on CExchange, this will enhance their user experience.

User Flow

I wanted to keep the flow simple and reduce unnecessary steps for the travellers to get to their exchange providers. Hence, design the flow to be short and less complicated.

Final Mockups

Interactive Prototype
