Google Pay is the Google payment system which allows you to make payments in the safest way possible.
It is very easy to use Google Pay, all you need to do is add your credit cards manually. IOnce you’ve added all your credit cards you can switch between one and another to suit your needs at any given time.
Remember that you can use it to pay in places where the point-of-sale terminal supports contactless payments, the same ones needed in order to pay by holding your card over them.
