Building payment solutions for brick-and-mortar

Submitted Jan 6, 2017

This talk is a case study of proximity payment,loyalty and personalization platform we built for Cafe Coffee Day, a brick and mortar coffee shop with more than 1500 stores across the country. Through this talk, I will elucidate some the challenges we faced and the highlight the learnings we gathered along the journey.


  1. How did we build a proximity payment solution that solves for security, ease of convenience and user choice?
  2. How to handle payments when the POS (Point of Sales) is offline?
  3. What challenges we faced and how did we solve these?
  4. What to consider when building for your own proximity payment solution?
