Currency Converter cum Wallet/ Euro to Thai

Going to Thailand on vacation? Exchange your euros to Thai Baht with L.Vey – A unique combination of minimalistic design interface and secure wallet for Android.

Project Background

With nearly 30 million visitors in 2015, 5.9 million of them being Europeans, the tourism industry in Thailand is at its zenith. Working in the tourism industry, the client knew that, in Thailand, there was no direct way to exchange foreign currency except at Foreign exchange Departments.

The client wanted to digitize the conversion process to allow people a hassle-free stay in Thailand, tourists and businessmen alike.

Client Objective

To save tourists the trouble to stand in the long Forex queues, the client wanted to create an e-wallet android application, which enabled its end-users to load their wallet with Euros and successfully convert them to Thailand Baht at then-exchange rates. In exchange for a small fee, the client further wanted to allow the user to access the converted amount by card-less withdrawal from a select number of ATM branches in Thailand.

While looking for a partner who could work hand-in-hand with client’s team and oversee a smooth app development process, the client chose SunTec to realize its goal.
