One of the very early trials for France Telecom.
This card has a pattern of regular 6 strike groups sometimes seen in laboratory tested cards.

Early design prototype.

This card from the builder of the very first Optical reader Alex Nyfeler.

Probably one of the very first France Telecom cards.

This card has a pattern of regular 6 strike groups sometimes seen in laboratory test cards, and seems to have been loaded with 120 units.

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.)

The deep blue was the color chosen for the French market, with variations of blue used until 1985. This “UN PRODUIT” design was also used on the prototypes for the Geneva university trials, but with a deep green color.
