When some people loved what GPay did, why did the rest still prefer cash?

the situation
In India’s metros, Google Pay became a habit almost overnight. Early adopters loved the speed, the convenience and the cashback offers that came with UPI. But beyond those first users, momentum faltered. In smaller cities and towns, people knew about GPay, yet they still reached for cash. Awareness had been achieved, but adoption had not followed.
Angle of inquiry
Why did people tolerate the small frictions of cash?
Were myths about digital payments keeping them away?
At what moments were new users dropping off?
Why weren’t merchants encouraging the switch?
To answer these questions, our team of behaviour researchers, UI/UX practitioners and visual designers spent weeks in the field, observing over 3,000 transactions across six tier-2 cities.
What we found
The barriers to adoption were not about product design alone, but about human perception and behaviour. People were asked for sensitive details too early in the onboarding journey, and many quit before trying. A persistent myth- that others could peek into their bank account- lingered. GPay itself didn’t feel different from the previous generation of e-wallets; it was just another app icon. And in day-to-day operations at the counter, confirming a digital payment often seemed slower and less certain than handing over currency notes.
The solution
System of solutions
We lowered the entry barrier by recommending that people be allowed to send as little as five rupees to someone they knew, giving them a safe way to try the app before sharing bank details.
We showed how trust could be made visible through constant cues that reassured users every transaction was secure.
We proposed tools that would accelerate confirmations and reduce the effort needed to complete a payment.
We suggested ways to add delight to repeat use with small hooks; from collectibles, to nudges that could turn tentative use into habit.
