I have placed 2 screen shots here. you see, read the screen shot of number 2. When I scanned the mobile security, see that it was written that 1 payment risk was found. Now what is written below that are 2 payment apps that are protected, including Google Pay. It is clear that you can definitely make digital payments on Google Pay's app. Google Pay has payment features like shopping, recharge, & bill payment etc.
Once you transfer more than ₹; 150 in a week, you get a scratch card from which the cash comes out, as you can see in the screenshot I have placed here. And on Friday there is a Lucky Friday offer in which if you make a bank transfer of more than ₹; 500, you can get a reward of up to 1 lakh.
If you send a link of Google Pay app to someone you know and that person joins Google Pay app through your link. then you get a reward of ₹; 81 on the first transaction of that person.
I also spoke to Google Pay's call center executive about the refund. I was surprised that the staff was very efficient and friendly too. Who solved my problem immediately.
