Introduction: Great Key Card Prank

Do you have access cards with the magnetic stripe at your business? This is a very simple and quick prank thats really funny too.

Step 1: The Tape...

All you need is tape and access to your workers key card, which might be tricky in some situations.

Just tape over the magnetic stripe and push out all the air bubbles and you're done! My dad tried it at his work and his friend was getting really angry at the machine for denying it all the time. Be sure to let them in on the joke before their head explodes! That would be bad. = )

Another permanent way to do it is just swipe a magnet over it and It will scramble up the card.

(I think...)

I had that happen with a cell phone.

Two things about that, one that would destory the card, and it wouldn't be a prank anymore. And two, the magnet can't touch the magnet to scramble it. It needs to be about a mm away to make all the particles face in one direction.

if you really want to mess with them, put a scratch in the strip with a key or knife, so if the reader is really choosy, it will reject it.

that's more of a permanent way of doing it. I want it to be temporary incase they actually need it

clear tape across the magnetic strip doesn't hinder the card being read... it is actually a good way to increase the life of the card. I put tape on the backs of all my credit cards to prevent the magnetic strip from excessive scratching. A good test so you can see it works is to put your card in a plastic bag from the grocery store so that only one layer of plastic is covering the strip, then run your card through a reader. It will read like new. So if you ever have problems getting your card to read put clear tape of the strip it will fix the problem..... I you want to mess with someone put electrical tape on the strip.

Thats weird, because I've tried it with a key card, not a credit/debit card and it won't accept it.

Might be since Atm slots are more picky than efpos

ATM = -------- <---- slot

efpos = /-----\ <------ [card faced flat]

those efpos are not mechanized... you move it by using your hand. And so it may have to allow some suspension of the read head. This may be since people tend to flex the card on insert.
