Spoofing Magnetic Swipe Cards

Posted March 14, 2012 by Chris

“Basically, a card stripe contains a certain sequence of magnetic fields which the reader detects as you swipe the card through it. The basis of all the card-spoofing circuits is to make some kind of electromagnet, put it next to the read-head and manipulate the magnetic field in just the right way to mimic a card.”

    Have you been able to get to the Serial Terminal then? From what you posted eeilrar, you were not able to get a prompt. As for your question about Voltages, if you feel more comfortable reducing the voltages, there is quite a bit of documentation on how to do this. I figured that since I was powering the Hard Drive from USB as well as the Arduino, they both were running around 5 volts. From what I understand from my reading, TTL signals run from 2 Volts to VCC (5 Volts) b110%.Even after losing the firmware on my drive, after recovering at least the APP Code and returning to the T> Prompt, by entering # has always enabled me to change the Serial number on the drive. It makes sense what you are saying about the CRC checksums, and I’m wondering if that is why I am not able to change the Firmware Revision, however the serial number seems to be open to change for me at pretty much any time.It may be a different command for your drive. I’m sorry, but I have not been able to find much documentation on the model number you gave me.If you look in my dropbox, about which I posted a few days ago, you may try the program SeDiv. It requires Windows XP, and you may need to change the date to like 2007 for it to launch, but it helped me get quite a ways in my attempts. There is an option on the main serial window for changing the Serial Number in there.

    I'd be less unhappy with that if I wasn't absolutely sure that "environmentally literate" meant "agreeing with hippies about both the severity of environmental issues and their ideal resolutions".(And, yeah, if they'd manage just-plain-literate first.But requiring environmental literacy, where you could pass it by agreeing with me just as well as by agreeing with a hippie, would be slightly less infuriating.)

    That’s really thinking of the highest order

    Do we really have a problem here? Surely there are existing laws against coercing people to sign contracts? And a marriage is just a contract like any other? If a person signs a contract under duress, that can be appealed in court and the contract rendered null and void. Isn’t that sufficient? After all a “marriage” doesn’t issue any obligations on the part of the parties, and the law doesn’t permit married men to kidnap, rape or assault their wives any more than it allows random strangers to.
