reverse engineering the old OVGU student card

This summarizes my reverse engineering from some years ago. Nowadays the Studentenwerk upgraded the reader rendering the plain money update futile.

The presentation was created with (landslide). The current version is prerendered available in presentation.html.

scripts

Included are show.sh for viewing relevant data from dumps and rand.sh for randomizing a dump.

dumps

Included is the randomized/edited dump (card.mfd) used for the presentation.
