ICICI Bank linked UPI ID to its ‘Pockets’ Digi-Wallet

Current Context: ICICI Bank announced the linking of a UPI (Unified Payments Interface) ID to its digital wallet ’Pockets’.

For this purpose, ICICI Bank collaborated with the National Payments Corporation of India (NPCI).
By doing so, ICICI Bank has become 1st one to link e-wallet with the UPI network.
Now, the customers of ICICI Bank can perform UPI transactions from their e-wallet balance instead of saving accounts.
Due to the linkage between UPI ID with Pockets, customers will be able to use their balance from their wallet for smaller transactions.
The new users and who are not customers of ICICI Bank, can now instantly get a UPI ID, which is automatically linked to ‘Pockets’.
And the customers who already possess UPI ID will get a new ID when they log on to the ‘Pockets’ app.
