Abstract: The present invention discloses a novel card for multi-purpose using, and more particularly, a card suitable for utilizing in a magnetic stripe card reader, an IC card reader and an optical driver to read out the data. The thickness (0.8 mm) of the card corresponds with to the specification of the ISO 7816. The card comprises a reading area of an optical disc, a magnetic stripe and an IC chip, and can be placed on a casing plate with a thickness of 0.4 mm so that the card for multi-purpose using combines the functions of a conventional dual mode (magnetic stripe/IC chip) card and a conventional optical disc, so as to achieve advantages such as convenience for magnetic stripe and IC chip reading and larger memory capacity asscessing.
