MyTaxyService will be released on Google Play Store, Apple App Store and Windows Store and so it must respect their market policies.
MyTaxyService will support only mobile devices newer then 2012. The mobile application will be suitable for devices with screen sizes starting from 4.2’
MyTaxyService is strongly dependent on MySQL as the main DBMS. It also uses PayPal as the only PSP.
MyTaxyService must support parallel operations coming from both Taxi Drivers and Passengers on the same DB.
The application doesn’t have a critical role inside the taxi system, since any of the actions done by MyTaxiService, can by accomplished by phone.
Since the payments are processed externally and the data is handled by an external DBMS, there are no specific security issues.
