Chip and pin!

<< < (2/4) > >>

strapping young lad:
that is indeed a bad thing

but back to this paranoid thing

if i intend going near a cashpoint i look around for dodgy looking characters hanging around, or plenty of passers by

a gang of 15 is quite intimidating and would put me off going near anything like that

datalas:
it would be nice to think that the chip and pin system worked on some form of one way seeded hash function, in which case the PIN is not stored on the card at all, and the details within the chip make very little sense without the corresponding cryptographic seed (i.e. the pin)

having said that, there isn't a great deal of scope for numbers in a four digit pin, but hey ho, I say go for a 25 digit random string :D

As I understand it, the PIN is stored on the chip, but fully encrypted (usually triple DES with 128bit keys)  :D

The most likely method of someone else obtaining you cash is sadly, as mentioned above - a large group 'requesting' your PIN  :(

strapping young lad:
or have alphanumeric instead

TimM:
That would be much better than a 4 digit code.

Some people might find it easier to remember.

Too late though, the billions have been spent already.

Tim.
