The first Libyan phone card was a 120-unit chip card supplied by the French company Gemplus. Initial field tests revealed a defect in the supplied phones, which sometimes overheated the chip, causing the card to warp. There is actually a variant of this card, which has the same side A, but has different writing on the side B: it seems that the first card was rejected after initial testing because the writing was too small, and so the second variant was supplied. They were printed in the same year and with the same run of 2000 pieces each, and both are very rare.
