There are many UPI wallets that serve the purpose, such as Slice, Mobikwik, Amazon Pay, and PayZapp.
The charges are as follows:
• Amazon Pay: 2.36%
• Slice: 2.5%
• Mobikwik: 2.95%
• PayZapp: 2.96%
All of these wallets allow you to transfer money to your bank. However, I do not recommend using them for high-value transactions, as wallets are not designed for such transfers.
