Its a digital wallet introduced by HDFC Bank.You Can add your all HDFC cards debit and credit too to this wallet in a organized and meaningful way so that you can pay or transfer money with a single touch without any extra effort.
User interface is nice. Its Simple Secure and robust app and you can also enjoy cash back benefit for travelling or utility bill payments.
I always use for air tickets and got offered every time.
But existence of this wallet on retail store is negligible so you cant use is daily life like paytm or Mobikwik but it is far better than those two wallets that I had mentioned. Balance transfer facility is also available. In one word its good.
