How can bank accounts enable UPI payments and what are some digital payment apps that provide this service?

When you link your bank account with digital payment apps like Paytm and Gpay, you can use the UPI feature for making payments. UPI, or Unified Payments Interface, allows you to connect your bank account to these digital service providers and enables you to make payments from anywhere using your linked device. It’s a convenient and secure way to carry out transactions without needing cash.
