Tackling impersonation fraud with in-app calling

Revolut recently introduced in-app calling to fight impersonation fraud, a major issue that led to nearly 10,000 complaints last year—2,000 more than Barclays and over twice as many as Monzo.

This feature lets customers securely connect with authorized representatives, removing the risk of scammers using traditional phone lines. By providing a safe way to communicate, Revolut aims to cut down on fraud and rebuild trust with its customers.

This works well because:

• Customers can confirm they’re speaking to a real Revolut employee, not a scammer.
• Secure, fast interactions stop scams before money is lost.
• It reassures customers with a reliable and safe support channel.

But in-app calling isn’t perfect. It depends on customers having access to the app, which can be tricky during outages or if credentials are forgotten. It also focuses on stopping fraud in the moment rather than proactively identifying risks ahead of time.
