Several public telephone card systems were used in Bolivia over the years by various telephone companies: magnetic, inductive, chip, remote memory… however, the first telephone cards were issued by the Entel company and were supplied by the Japanese Tamura. These were thin cards, the type used in Japan, with a silver back, and a series of four values was issued: 10, 20, 50 and 100 Bs.
Later the series was reprinted with the same images on the front, but the reprints can be easily recognized as the back is bronze in color.
