Germany Bamberg SEL
test karte (SEL internal written)
SNR 601 card #5

This wave design is also known on other COPY cards, but this card FD234 was used by SEL, and has the Villingen-Schwenningen address used on most of the SEL cards from 1982 onwards.
We have seen FD065, but that series was probably for copycards, and has the Heinz Schoemacher KOLN (Cologne) address.
The red hand writing “Test Karte” is found on some of the Bamberg test and service cards, where the cards were repurposed, in the same hand writing.

The following are all the FD series we have identified as issued to SEL for testing and internal trials
FD022 (old copycheck)
FD024 (orange band)
FD044 (orange band)
FD074 (wave design)
FD103 (orange band)
FD144 (orange band)
FD234 (wave design reference card)
FD363 (orange band)
FD413 (orange band)
FD474 (wave design)
We have observed that all these FD numbers end in either a 3, or a 4, and cannot be a random pattern?? (except the FD022)
The only Deutsche Bundespost Bamberg card with FD number is the FITCE Regensburg card from 1985 with FD1265. The FD series 022-474 range in issue date from 1982 up to 1983.

After some initial testing early in 1980 with chip card technology from Turin, Italy, SEL began testing with Copytex later in November 1980. The chip technology was found to be of poor security, and SEL wanted an inexpensive card, that still retained features that were difficult to counterfeit. Copytex had developed a low priced paper card that employed “LICHTDURCHLASSIGKEIT”, a secret area on the card that allowed special light to pass through (infrared?) was used to authenticate the card before allowing magnetic units to be used from the magstripe. The goal was to set up phonecard payphones for the field trials in the city of Bamberg 1983-1985.
In this section we are please to show a very comprehensive look at the cards used in development.
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.
