Taiwan has been using the Landis & Gyr optical technology cards for over 10 years, before switching to the chip system. The first cards issued were two definitives, 100 and 200 units, both red, without a notch, and with the optical band of the same color. In the following years, the value of 100 units was reprinted several times, with optical bands of different heights; while the definitive with the value of 200 units was printed only once, but blue. It was only in 1988 that the first illustrated cards began to be issued.
