Germany L&G Frankfurt demo 3
Orange-Red Sodeco
Serial number range
00 200235  to
00 200986
This card is much lighter than the normal dark red Sodeco cards, and is even slightly lighter than the color later used for the Deutsche Bundespost series of trial cards.

The first demos for the Frankfurt trials of L&G technology are all this type. (Vermillion Sodeco) The early trials, test and service cards are all the same deep wine red colour (1980-1982). The second stage of testing (1983-1984), where the Deutsche Bundespost branded cards begin production, the colour of the cards are bright red.
Toward the end of the Frankfurt trials in around 1984, cards with thermal band are produced, but the trial ends with the selection of Siemens Chip cards chosen for the National phonecard telephone network.
