The goal of the project is to keep the scammer on the phone for as long as possible by engaging them in a lifelike, but meandering conversation. This is done without any input from humans other than the responses from the scammer.

A video shared by O2 of Daisy in action suggests the scammers very quickly become frustrated and angry at the way it responds. This includes giving out fake bank account information and personal details.

Murray Mackenzie, Director of Fraud at Virgin Media O2, explained that Daisy is "turning the tables on scammers — outsmarting and outmaneuvering them at their own cruel game simply by keeping them on the line."

He recommends anyone in the UK worried about fraud to forward any call or text they suspect of being from a scammer to 7726 for free so it can be investigated.
