A nice woman is working in a bank call centre.

We hear her talking to a customer on the phone.

She's taking them through security precautions by asking for two numbers from their PIN details.

She asks them to repeat the details slightly differently asking for two other numbers.

Suddenly her face goes from friendly to sinister.

She talks directly to camera saying 'did you see what I did there?'

We realise she has just tricked the caller into giving her their full bank PIN number.

She smirks and walks away with all the other call centre staff.

The Barclays bank brand voice delivers the lesson that no bank will ever ask you to reveal your full PIN number.
