What is a Payment App and Why Should You Care?

A payment app is your digital cashier. It allows people to send and receive money instantly via mobile.

But it’s more than that.

It’s also a data goldmine, a brand loyalty engine, and a revenue stream, especially when you own the platform instead of paying someone else’s transaction fees.

Still using third-party apps for payments? You’re leaving money (and data) on the table.

With a custom P2P payment app built by TechRev, you own the ecosystem. You make the rules.

• Users link their card or bank account.

• Tap. Send. Done.

Behind the scenes? Complex banking APIs, bulletproof encryption, compliance checks—things you shouldn’t have to stress about. That’s where TechRev comes in.
