[sigplus] Critical error: Image gallery folder PAdirectReader is expected to be a path relative to the image base folder specified in the back-end.
The P.A. Direct Reader simply reads all three tracks of data on a standard mag stripe card, and displays that data.
Originally, the setup was not going to use a computer, but run from an arduino. However some last minut problems with reading multiple tracks, and some hardware problems led to the use of a PC. Processing was used to both read the data from the card reader, as well as display/erase the data on screen.
