Card having cash paying function and spent amount recording method

摘要

The present invention provides a method of producing hologram tapes corresponding to a large number of prepaid cards having different characteristic codes from one another, using one hologram master plate. ;Hologram tapes are produced in the following manner. Namely, an elongate flat image expressing a random number in the form of a bar code is prepared. A hologram master is prepared based on the prepared flat image, and the prepared hologram master is wound around the surface of a drum 110. The etching technique is applied, to prepare a drum-shaped hologram master plate 101 formed with micro relief corresponding to interference fringes on the surface of the drum 110. By rotating the drum-shaped hologram master plate 101 on the surface of a long material sheet 120, the micro relief hologram master 111 on the surface of the drum-shaped hologram master plate 101 is repeatedly transferred onto the material sheet 120. Then, the material sheet 120 to which the micro relief hologram master 111 has been transferred is cut into hologram tapes each having a specific length.
