Theory:
•
Detailed Problem Definition:
With the rise of digital wallets and UPI, payment apps have been on a rise.
Google Pay has the highest reach but it is PhonePe with the most
transactions. The businesses make money by commissions on
transactions, much like a credit card company. However, not all
transactions generate commission, transactions like transferring money to
a bank account don’t generate a commission. These transactions,
although don’t bring in money, they bring in a customer.
How might we increase adoption of the app and in turn increase the
number of transactions?
