01 | WHY THIS PROJECT
Improving UPI payment flow for elderly vendors scored highly for research availability, practical scope, real India relevance, and internship-level execution feasibility.
Project selection matrix result from the research package.
Strong public evidence from app reviews, Reddit complaints, and fintech articles.
Core flow can be constrained to home, recipient, amount, review, PIN, success.
Achievable in a focused 10-day case-study sprint.
02 | EXISTING FLOW AUDIT
Existing UPI flows often optimize for feature density and speed, but elderly users need stronger clarity at payment-critical moments.
Elderly vendors struggle to send money confidently because they cannot quickly verify recipient, amount, balance, and PIN purpose in one calm flow.
03 | RESEARCH EVIDENCE
"I check the name again and again because I am scared of wrong transfer."
"Too many options on home. I only want send money and balance."
"PIN and OTP prompts are confusing when I am in a hurry."
"On failure screens I cannot tell if amount was debited or not."
