SEL set up phonecard payphones (using the Copytex system) for the field trials in the city of Bamberg 1983-1985.
In this section we are please to show a comprehensive collection of the cards used in testing and field trials.
The copytex cards were initially designed for copy machines in universities, and other facilities, but Copytex had it’s initial market success with the Bamberg trials, and we know of NO significant copycard systems at the time of these test and trials 1980-1985. All of the cards shown here are part of the PHONECARD development of SEL. SEL were acquired by Alcatel in 1986, and Alcatel began developing it’s own version of the Copytex technology. This is why early Alcatel cards are actually of paper, with same position magstripe from around 1986-1987.
