Classic example of how you're going to have problems with going cashless...
2 weeks ago I lost my card at work, hey-ho, cancelled it promptly and waited for a new card to arrive. We have a joint account so my wife still can pay stuff, get cash etc etc.
2 days later,, before my replacement card arrived, her card was scanned online, someone using her details ( I have no idea how this actually works) so the bank shut her card off once they confirmed with her it was a scam.
Now, we have no access to cash, no way to pay anything for a few days. Luckily I always have maybe£200 or so in cash stashed so it wasn't a disaster, but it was very frustrating.
Weird things happen, I'd never lost a card or had a problem in 45 years of banking, the minute I do, it was
almost immediately made 20 times worse by my wife's card issue.
We have decided to start keeping a few hundred quid at home as a contingency . It's highly unlikely to happen again, but had I not had that little stash i wouldn't have even been able to buy a 20p coffee at work, let alone the serious stuff.
It's (cashless) all very wel and convenient...until it goes wrong.
