X.CHANGE APP by alexandros stasinopoulos from taiwan

Returning back home after international trips usually we are left with foreign currency banknotes that we either exchange at the airport upon our arrival (no matter the exchange rate) or we just keep them in a drawer.
Deutsche Bank with a simple app could show that it cares for even these small details and could micro-manage even these small amounts for its Customers.
The Customer could input in the x.change app the currencies he/she would like to follow and Deutsche Bank would notify him/her when it more profitable for the Customer to exchange the foreign currencies he/she possesses.
