01. The Problem
Small merchants in India needed a faster, friction-free way to accept digital payments without relying on expensive PoS hardware or dealing with faded, non-scannable QR stickers.
02. Research & Insights
We analyzed payment behaviors across 50+ local merchants. The data showed that scanning took an average of 12 seconds, while tap-to-pay could reduce this to under 3 seconds, significantly improving checkout throughput.
Key User Insights
- 01.Merchants do not want to download another app just to see if a payment went through.
- 02.Customers are increasingly comfortable with NFC but default to QR because physical infrastructure is lacking.
- 03.Visual confirmation (like a blinking light) is as important as audio confirmation for busy merchants.
03. Strategy & Design
Core Strategy
Develop a hybrid infrastructure leveraging inexpensive NFC chips embedded within durable acrylic stands that also feature dynamic QR codes as a fallback mechanism.
Design Process
Focused on an ultra-minimal merchant dashboard for real-time settlement tracking. The physical stands were designed to be highly visible, durable, and instantly recognizable on crowded store counters.
04. Execution & Challenges
Implementation
Built the backend with Node.js and the merchant dashboard using Next.js. Integrated with leading payment gateways to ensure settlement within T+1 days.
The Challenge
"Hardware distribution is significantly harder than software. Finding the right manufacturer for the acrylic stands that could reliably embed NFC tags without signal degradation took weeks of trial and error."
Learnings
Merchant onboarding needs to be instant. Any delay in activating the NFC tag led to immediate churn. We automated the backend provisioning to happen in under 30 seconds via a simple WhatsApp bot.
05. Outcomes
Piloted with 50+ merchants in New Delhi.
Processed over ₹2.5M in test volume.
Achieved 99.9% uptime across the pilot phase.
