What can be the business model for Google Tez? How is Google earning by giving free money to users?

Google Tez is a mobile payments service by Google, targeted at users from India. It operates atop the Unified Payments Interface, developed by the National Payments Corporation of India. It can be used where UPI payments are accepted.

There’s no such thing as free money (or a free lunch)

If you’re getting something for free, you are being sold. Google is selling you to advertisers by knowing you better, and Tez makes sense because:

They know what you’re looking for (Google Search)

They know what you’re watching (YouTube)

They know where you’re going (Google Maps)

They know what you’re reading (Google Feed)

They know what you’re communicating (Google Mail)

One big gap is that they don’t know what you’re spending on.

Google Tez will give them that answer as well.
