Magnetic Card Swipe Reader
Some time ago there were several posts about Magnetic Card
Readers and how to read the data. One of the files even had a C
program called Swipe.C that would read the data when a card was
pushed thought the reader and could be displayed on screen or
saved to a file.
A few weeks ago, I bought a SR&D mag card swipe reader in
San Diego for $2.50. Using the information in the files posts
dating back to Jan 92 , I was able to connect my swipe reader to
my PC and using the program could read and store the contents of
the card. The problem was that the data was a columnar listing of
255's and 191's. I have deduced that the 255 is FF hex or 1111
1111. The 191 is BF hex or 1011 1111. Since I am not a
experienced programmer, I need some help in determining how to
read the data. I want to decode a card so that I can use a mag
card reader as an input device for a future robotics devise that
I have in mine. Any help would be appreciated.
Here is the partial listing that is giving me trouble. To
conserve space I list the data in several columns.
255 255 255 255 etc.
