Cash withdrawals - disabling the facility

Not a stupid question at all, some less than sensible answers though.

Using the same pin on several cards is not stupid either and can be more secure.

Unless I'm missing something I can't see how having the same pin on multiple cards can be more secure?.

More pins are more difficult to remember, people might write them down to remember, writing a pin somewhere makes it less secure. (And remember I said 'sometimes').

You never actually said "sometimes"

I read an article somewhere that reported a study as to whether having unique passwords for different websites was better than using the same password for all sites.

The conclusion was that having different passwords for accounts was less secure because the shear volume of passwords that people needed to remember led to them writing down the passwords/password hints.

I don't really agree with that argument in regards to passwords. Your much better writing down passwords in a notebook than using the same password on every site. The chance of someone breaking into your house and stealing your password book is miniscule compared to one site being hacked and your password for every site being obtained.

But there isn't any need to write down any passwords or pins for cards If you use a system to remember them.
I have a system I use to have a different pin on each card based on digits printed on the card. So all i need to remember is one "algorithm" to have a different pin for each card.
I also use a similar system to have a different password for each website.
