Revolut has issued a Christmas warning to customers about a devious new way criminals are stealing money from unsuspecting victims.
The e-banking app said thieves are using a technique called "shoulder surfing" which sometimes involves fake taxis. Criminals will target an individual, and try to observe their mobile phone passcode by spying on them by looking over their shoulders.
Once they see the passcode, they will try to steal the phone. Sometimes this is done using an accomplice in a fake taxi, where the thief will wait until the victim is leaving and calls their fake cab.
