Jonathan Schwartz @ News.com has an article that will be making the rounds quite a bit regarding unencrypted information on some of the new credit cards. I fully expect our Makers to make a text to speech version that screams out names as people walk by -

“They call it the “Johnny Carson attack,” for his comic pose as a psychic divining the contents of an envelope. Tom Heydt-Benjamin tapped an envelope against a black plastic box connected to his computer. Within moments, the screen showed a garbled string of characters that included this: fu/kevine, along with some numbers. Heydt-Benjamin then ripped open the envelope. Inside was a credit card, fresh from the issuing bank. The card bore the name of Kevin E. Fu, a computer science professor at the University of Massachusetts, Amherst, who was standing nearby. The card number and expiration date matched those numbers on the screen. “ Thanks Sdwarf! – Link.

    RE: “Build this kit” Illustration…

    I’m almost positive the Parallax RFID reader sends serial data in TTL level output, so you can’t directly connect it to the computer as shown above.

    I can confirm that at least the CrystalFontz displays have solderable jumpers for inverted TTL that allow direct connection to the Parallax reader and a 5vdc source.

    It looks like the “RS232 Line Driver” in the schematic above is intended to be a level converter from TTL to RS232 levels, so he’s not connecting it directly above.

    You are right though that it can’t connect directly to the computer without a level converter.
