Magnetic cards supplied by Autelca have been in use up to 1994; the first cards have been a set of 4 definitives, B$ 10 (180,000 printed), B$ 20 (150,000), B$ 50 (120,000) and B$ 100 (100,000).
At the end of 1994, magnetic cards were withdrawn and an optical system by Landis & Gyr was introduced and is still in use.
