All you need to do is take a picture of the receipt when you buy anything, answer a few questions, and you will get rewards instantly in your PayPal account.
You can upload the pictures from different stores and restaurants for earning rewards. You can get these rewards redeemed for money through PayPal or for an Amazon gift card.
You should keep in mind that you should upload the receipt as soon as you purchase because Receipt Hog accepts less than two weeks old receipts.
Once the account is created, you can upload the bill receipts, and it will automatically calculate the points as per the total amount of shopping.
As soon as there are 1000 points in your account, you can redeem them through your PayPal account; the value of 1000 points is $5.
