I need an app where the user can scan a barcode ticket using his phone camera or enter the barcode number manually. The app will the communicate with a back-end server to request all ticket details and amount to pay. The amount to pay is shown to the user and the user can choose to pay using Apple pay/ android pay for example. After paying the result is send back to the server.
The app will be piloted first in Canada and if successful other countries will follow.
I'm looking for an offer to get to a first working prototype. Android or iPhone, if can both. I also need the full source code.
I have 20 year of software development background but I am new to mobile apps development. Parts of the back-end I already developed. Please let me know if you need anymore details. Thanks.
