Truecaller users on Android have been able to transfer money within the app since earlier this year when developers introduced its UPI (Unified Payment Interface) protocol. Starting this week, a new feature has been added to the system so that users can send payment requests to other Truecaller users.
If you're using Truecaller, then you should know that in order to complete a transaction, you must enter the registered MPIN when prompted. The links that any Truecaller user can now create can be shared via SMS, email, messaging apps, or posted on sites. Only when they are clicked they will redirect the user to the Truecaller app to complete a payment.
The bad news is the new Request Money feature is only available in India for the moment, and it doesn't look like it's going to be made available elsewhere anytime soon.
