With the I amsterdam City Card you don’t have to worry about your trip to Amsterdam. The app includes the most important aspects of visiting a new city. The challenge of building the app lies mainly in the way all these different aspects have to interact with the app since they sometimes refer to external websites and scheduling tools. For example, you must be able to scan your City Card smoothly in the tram or at a museum without your Apple pay or Google Wallet appearing, but you also have to be able to reserve a time slot at a museum of your choice.
To summarize: the app should help visitors navigate, plan and make reservations before and during their visit to Amsterdam. This not only requires constant innovation, but also a very secure working method. Updates are offered in a live environment. Testing in the most all-encompassing method is a must before updates are pushed to a live environment.
