Kelvin Lin's profile Eliminate Your Remaining Foreign Currency, Powered by Addweup Ltd.

Have you ever traveled abroad?
As the journey ended, there were always leftover foreign currency, wasn’t it?

A lot of people love to travel overseas, but when they come back, they don’t know how to deal with those remaining foreign money. And we discovered that nearly 96% of departing passengers had the same problem.

Changes seem unimportant, but when we gather those small amount of money, it could be valuable for users and society.

P.S. is a service powered by Addweup Ltd.

Service Blueprint
There are a lot of things to do during the trip, and we hope to make it simpler for passengers. 

In order to provide a better service, we thrive to cover as many scenarios as possible. Such as taxi, mileage and online shopping.
We observed that the exchange counters in departure areas are seldom used. So it gives us an opportunity to make the booth more valuable.
