A Swiss company called Lestra Engineering AG was looking for a software outsourcing partner to take over the implementation of their project.

There are more than 1800 vending machines located around Switzerland. So, the task was to create a mobile app called Smarpay, which would allow making an order from the machine and paying for it.

As a result, Softengi team created an app performing all steps of the projects, starting from the design, app development, testing and finishing with the final product release.

In order to complete the project, the following specialists were involved: iOS Developer, Android Developer, Tester, Architect and Project Manager. The whole process has taken six months.

The Solutions Used for Project Implementation

  • Caching of resources received from the server and updating them only in case they are amended allows to reduce network traffic and increase app response (in case of absence of amendments in the resources, their load from the local cache occurs instantly).
  • The app includes the initial caching version of resources, which allows to start the usage of an app at once, even if the internet connection is not available.
  • QR code scanner automates the input of the machine number.
  • Display of all vending machines as markings on the map with an opportunity to quickly move to any of them.
  • Use of advertisements dynamically uploaded from the server.
  • Calculation of the distance from the device to a machine.
  • Display of the closest machines on the main page of the app (integration with Google Maps).
  • Sending of push notifications to inform the user about the closest machine.

Smarpay Functionality

Therefore, Smarpay app allows its user to:

  1. Search for the nearest vending machine (Google Maps integration);
  2. Choose an item of food by a QR code;
  3. Execute payment transactions via sending of a text message.

There is no need to go through the registration process in order to complete the payment transaction. This app was crafted with iOS and Android users in mind. Currently it is available for download on App Store and Google Play.

Plans for the Future

In the meantime, Smarpay seems to be broadening its area of influence by adding ticket machines, photo booths, gas pumps, flower and farm shops to its footprint.
