In the early development of optical phonecards by Landis and Gyr, France was one of the early market goals for L&G. This is one of two type2 laboratory cards manufactured for France. The deep blue was like chosen for the Paris first stage, and Light blue for expanded rollout. France used variations of blue in the L&G cards until 1985 when RED was introduced to allow for less confusion when Generic test and service cards of L&G were changed from RED (Stu11) to BLUE (used for MOST Structures of test and Service). This laboratory design was also used on the prototypes for other countries for the Geneva university trials (green), and other countries (Austria-Yellow, Swiss-Red, Belgium-Orange etc.)

In the first years when L&G was investigating the phonecard product, a few magnetic readers were acquired from Hewlett Packard, and installed in payphones to test customer behaviour with the phonecard product.
It is understood that small scale field trials were conducted in the area of Montparnasse, and some of the train stations in the area.
This plain L&G branded card is the only known type that was probably used in this early field trial, or at least was the test card used. Later the Magstripe phonecard phones were used in the Frantel Windsor hotel: HOTEL FRANTEL

In the first years when L&G was investigating the phonecard product, a few magnetic readers were acquired from Hewlett Packard, and installed in payphones to test customer behaviour with the phonecard product.
After some small scale field trials, L&G installed some Magnetic phonecard payphones in the lobby of the Frantel Windsor hotel. Cards were encoded upon payment at the lobby desk, and magnetic uncoded cards are actually MINT UNUSED cards, because they were only charged with units just prior to usage by the hotel customer.

These are second stage of testing (1983-1984) with final phase field trials, where the Deutsche Bundespost branded cards begin to be used by the public. the color 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.

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.
