You can use monies to convert them into cashback. When your number of collected monies increases, your conversion rate increases and you can earn higher cashbacks.
The reward rate looks like this:
1 % : 3,00,000 > monies
1.5% : 5,00,000 > monies > 3,00,000
2% : monies > 5,00,000
Note: Rotate the dialer on the rewards page to successfully convert the required amount.
