SBI buddy is a mobile wallet that allows the user to transfer amount to his contacts with the click of a button. If the user is a vegetable vendor he can receive cash from his clients without dealing in paper money. At the end of the day be can transfer his earnings to his bank. Money can also be transferred into the bank account of ones child who may be in a hostel. All this happens instantly along with the confirmation received by SMS. Of course one can recharge his phone or DTH TV . Other shopping options are also available. The wallet can be loaded by one's debt cum ATM card. If the user wants to send the money back to his bank, he can do it instantly.
The application needs an unrooted Android phone. The application should not be shared with anyone via Shareit or similar apps. It is because the wallet app would consider this as rooting and start crashing after that. Then it would have to be downloaded again through the Play Store. Perhaps, this is because of the security issues.
In nutshell online business has become much easier now. I feel that this virtual wallet is poised to replace the paper money in the near future.
