The client needed to make their vending machines “SMART”. So as to be able to accept digital modes of payment as an upgrade to their previous model  which would accept only cash.

“Our machines sell better because people prefer digital payment over exact change in vending machines” 

Sandeepan Bhardwaj

CEO, Swaraj Industries

The Challenge

Writing software for unmanned machines present some very unique challenges like:

  • To be able to work fully offline if internet connectivity unavailable to the vending machine.
  • To be able to track user behaviour and return to its original state if user stops interacting.
  • To be able to uniquely identify and control each vending machine, their products and pricing through acentralised admin panel,This is even more challenging because some machines may be offline at any given point of time.
  • To be able dynamically serve video advertisements.
  • Seamless synching of all transaction data and user behaviour to the centralized admin panel for reporting.


The Approach

Though the user interface of vending machine is simple,there are some unique challenges in designing it as it is a touch based non monitored, independent system.

In the first phase, we developed the required models and relations for optimum of storage of data locally



“We used a customer first approach which helped us visualize all the situation which may arise when a customer interact with a machine”
