We've officially been using Chip and Pin in all stores since around February 2007 in the UK which has made life a lot easier in many ways but ever since it's introduction, I for one have had concerns over the claims that it's safer. I agree that it is (or was) harder to find out someone's pin number but has it made shop assistants more complacent?
Stacey and I have a joint Egg Card -I know, what WAS I thinking ;), anyway, these two cards look identical and even had the same pin number and as a result, we recently got them mixed up. I can't say for sure when it was we got them swapped around but one thing for sure is that it was a good couple of months ago. Ever since, we've both been using the wrong card without being questioned, at a guess, I think this has gone on for around 4 months and I only noticed the other day when I looked down and read the name on the card when I was paying online.
This for me is pretty concerning, ok it's because I know the pin, the shop assistant assumes I'm the card holder and doesn't check the name (which the used to when they were forced to check the signature -if they bothered checking that of course ;)).
I think it's also easier to find out the pin too as people aren't overly cautious about entering in their number, I've even seen an old lady in a wheelchair type her pin in on the terminal which was on the desk while she remained lower down in the wheelchair, allowing anyone within about 10m to read what she was typing in. She then promptly put her card back in to her bag and hung it over the back of her wheelchair -where any unscrupulous person could come along and "borrow" the card. It's not just the elderly however, even the young allow other people to read the pin.
I would be interested to know the statistics in crime reduction, I wonder if they're as high as the government were predicting or whether these predictions failed to include the main weak link in the system -us.
On the whole however, it has made life easier and I like Chip and Pin despite these (human) errors, to an extent I think it has made it harder for the criminal to steal (though before he had to learn the signature) but I think people need to be more cautious.
