[OT?] Destroying data on bank card
I like to keep my old bank cards intact and use them for jobs around
the house. My worry is that the data on the magnetic strip can still be read. What is the best way to destroy that data without messing up the card for D-I-Y work. ---- Does a domestic microwave detroy data on a magnetic strip? I tried using some of those strong magnets taken from a hard drive. I put one above and one below the bank card and then slowly drew the magnets along the magnetic strip. Is this enough? Is it better to do this relatively quickly or relatively slowly? ISTR something about vertical and horizontal magnetic polarization and maybe this is something I have to deal with in case it makes the magnetic data harder to destroy??? Is it better to scratch the magnetic strip with a sharp point? |

Why don't you just pick up a few mobile-top-up cards, loyalty cards ect
for your jobs around the house and dispose of the bank cards the "Normal" way? |

Cut up your cards, kaing sure you cut the magnetic strip, the chips and the number. Then place half of the pieces in two separate bins. Christian. |

Bulk tape degausser works well, but, in my opinion, these cards should be totally destroyed. You can get a small copper plate for "jobs around the house". |

If the magnet is strong, it will take out the strip data. I expect a record antistatic gun will do the chip. Until my replacement for my cracked cashcard arrives, I will not be experimenting, but will report back. The embossed data and the card ID on the signature strip are enough to be fraudulent, but normally when the following card is used, the other card is disabled by the supplier. As has been said points cards are easy to get, so easy that most of the skimmers used to use them as blanks. With the phasing out of magnetic strips for transactive use, it appears that more card fraud is committed via the internet, phone, or mail order. http://news.bbc.co.uk/1/hi/business/4418140.stm John Schmitt -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ |

What is the best way to destroy that data without messing up the card for D-I-Y work. I had cause to test this recently with mag stripe cards we use at work. A few wipes with a rare earth metal magnet from a hard drive will usually do the trick. It is probably a good idea to sandpaper off the mag stripe and signature strip including card verification value. There is significantly more information on the mag stripe than appears embossed on the card, but the card itself may be potentially more useful to fraudsters than the information in it. I don't think a microwave oven would be a particularly good way of erasing a magnetic strip but it would probably be a good way of ensuring that any smart chip never functions again. -- Alistair Riddell - BOFH Microsoft - because god hates us |

I like to keep my old bank cards intact and use them for jobs around the house. My worry is that the data on the magnetic strip can still be read. That is only part of the problem, the other part is the numbers embossed on the card. While the expiry date would normally be obsolete, its often possible to guess the new one that is on the card that replaced it. So, while its easy enough to remove the magnetic stripe and signature strip, its harder to get rid of the embossed numbers and still have a useful bit of plastic. What is the best way to destroy that data without messing up the card for D-I-Y work. Hard to say if you dont say what you use them for. Does a domestic microwave detroy data on a magnetic strip? Nope. I tried using some of those strong magnets taken from a hard drive. I put one above and one below the bank card and then slowly drew the magnets along the magnetic strip. Is this enough? Normally, but its hard to be sure that the data cant be extracted by someone who cares enough to go to the trouble. The card isnt much use without the pin tho. Is it better to do this relatively quickly or relatively slowly? Doesnt matter. ISTR something about vertical and horizontal magnetic polarization and maybe this is something I have to deal with in case it makes the magnetic data harder to destroy??? Its better to just remove the entire magnetic stripe. Is it better to scratch the magnetic strip with a sharp point? Sandpaper is better or run it against an abrasive wheel or wire brush on an angle grinder. Bit risky finger wise tho. |

Not sure how you delete the information on them but I'm curious about
what you use them for?? |

In addition to using old credit cards, buy a new deck of playing cards to use for some of these purposes. You can use two or more at a time to increase stiffness. We've done that in certain hobby building. As Alex says, your pin or password are not on your card. Running a small dc magnet should remagnitize the strip unreadable. Might take a good one, run a magnet over it, and try it in a reader. I am betting it won't get read. Dave C |
