Landis & Gyr optical cards went into circulation in Tunisia in 1983 and used for several years; the first issue includes three red ordinary cards without notch, with a paint-type print, and face values of 10 units (1,000 issued), 20 units (179,200), and 50 units (90,600). The 10-unit card is very rare because only 400 were sent to Tunisia, while the others were destroyed.
From 1992 to 1994, three more Landis & Gyr cards were issued; later the Urmet magnetic card system was adopted, which was used until 1996, and finally it was decided to adopt the technology with chip cards.
