That is something we would all want to know, isn’t it?  

Cashback is the return of a percentage of your total bill (not including any amount paid with promo codes) in the form of cashback credit. 

For example, the restaurant offers a 10% cashback. Your total bill at XYZ Restaurant is Rs.1000 then you pay Rs. 1000 and Rs. 100 will be added as cashback credit in your Fave account. On your next visit to the same merchant, some percent of the cashback credits added at the time of first transaction will be transferred to your bank account and you will earn new cashback credits for the current transaction and the cycle goes on.   

To view any existing cashback in your account, head to the 'Account' tab and click on "Savings".
