A common electronic security technique involves a rolling code sequence where the key changes everytime it is used. The key is one of a series that must be used in order.
Some folks have trouble remembering just one PIN but for the rest of us we could probably manage a double PIN.
So for
each card there are two pins but the system will only accept the one not used last.
If a thief memorises you card at the ATM or supermarket checkout whatever he cant steal your card and use it because the alternate number is now the expected one.
If you find one number does not work, probably because you forgot which one you used last time, just use the other one.

The same idea, but more clever. [Overpanic, Oct 04 2004]

The problem here, as it has been pointed out multiple times [see annotations in links], is that ATM cards are generally not "stolen", for the exact reason that it is too hard to find out someone's PIN. The most common scenario is that someone will be held up at an ATM right after they've inserted their card, so the thief just instructs the person to enter their PIN for them. That's of course, where the Panic PIN comes in handy...which, by the way, if you haven't noticed, is the most popular idea on the HB. |

Are you sure that my wife can't smack me upside the head with it? |
|

Yeah, Overpanic, but then the thief will just wait to hold
you up until you walk away from the ATM with the cash,
as has also been mentioned several times in the Panic PIN
(which hasn't had much effect on the mob mentality over
there that somehow still thinks it's a good idea). |

I don't know about you, [oxen], but I don't generally take large sums of money out of the ATM at one time. Maybe $100? It doesn't seem that profitable to me. |
|

Yeah, it is. I pulled one off a bus a few years ago. He was seen leaving the apt. building I lived in as I was parking. I sez to myself, I sez "S'picious lookin' feller" - went upstairs - Landlord's door was off the frame. Back in the car I went, and down the road I went. At nearest bus stop - thar he wuz - sorta had my landlord's cheapie stereo in his big-ass bag. He's doing 5-10 yrs., with at least 1 to go as of this writing. So, yeah - $100 bucks is a windfall. |
|
| |
That's all fine and good, but $100 isn't as much as a windfall for me as $500 is. So if something is in place that will dissuade individuals from thieving me at the ATM machine, where they could get as much as $500 at one time, I've saved $400. |

When it comes to getting held up, I no longer care about
the money. I just don't want to get clobbered over the
head with a baseball bat for any amount of money, and
none of these _______ - PIN schemes are going to do
anything about that. |
|
| |
Yeah, that's why you need a PIN knife. A safety PIN just isn't going to cut it. |
