Abstract

With the popularization of various types of plastic cards with embossed pattern, such as credit cards and ID cards, there has been the need for hardcopy of embossed pattern to identify the user. At present, embossed pattern is copied with an inprinter using carbon paper. We have developed a method of making hardcopy of embossed pattern, based on a new concept. In this method, embossed pattern is read optically by a contact-type image sensor, and converted into electrical signals. The hardcopy of embossed pattern is obtained with an image printer. Using this method, not only embossed pattern but also image pattern can be processed and stored as electrical signals.
