Magstripe cards were originally manufactured by Autelca on behalf the Bahrain Telecommunications Company B.S.C. There was a set of 4 definitives with use instructions in both English and Arabic and black control numbers on the other side. Quantities printed were: 160,000 for both the 25 and the 50 units; 300,000 for the 100 units, and 80,000 for the 200 units. In 1988 the Autelca cards were withdrawn and GPT cards were introduced.
