The foundation of any strong relationship is said to be trust, yet apparently the principle doesn’t quite extend to your finances.
According to research from Defender Note, more than two thirds (67 per cent) of UK adults keep their bank card PIN hidden from their partner.
Men appear to be more careful with the numbers, with just 31 per cent sharing their PIN with their other half, compared with 35 per cent of women.
Split by region, couples living in London are the least likely to share their PIN with each other, with just 30 per cent doing so, while those living in the East Midlands are most trusting (42 per cent).
Londoners are more trusting when it comes to the workplace however, with four per cent admitting they had told a colleague their PIN before – a higher proportion than any other UK region.
The study also found that 54 per cent of UK adults have never told anyone their PIN, only five per cent have trusted their friends with the information, while four per cent have trusted their siblings.
Worryingly, five per cent of people surveyed admitted to storing their PIN on their phone to help them remember it, while two per cent keep a note in their wallet or purse.
Men are three times as likely as women to use an anniversary to remember their PIN, while more women choose to keep the random digits allocated to them by their bank.
Morgan Rothwell, CEO of counter-fraud company Defender Note, said: “It’s a little surprising that so many couples don’t trust each other with their PIN, but people are right to be careful when it comes to sharing their personal information.
“Criminals continue to come up with new and covert ways of defrauding consumers and the less people that have access to your account the better.
“In the last year alone, there’s been 26 per cent rise in card fraud in the UK, with last year’s total bill reaching £755million.”
