AN #17 - Telephone card reader


The following example was donated by Erich Linsmeier

The software reads a telephone card and displays the info on a LCD screen.
It works for German telephone cards and I think it will work for most countries.
You only have to change the currency of course.
When you have tried it and it works for your country, it would be a nice idea to send Erich a message so that he knows it works in other countries as well.
New : 19-9-1998
Erich has enhanced the program and even provided a PCB in laserjet image format.
Here is the content of the readme file.
