Abstract :
The memory cards are widely used in several applications. This paper is intended to design and construct of the encrypted card reader. The basic building block in this design is the card reader, amplifier, multiplexer, and PC parallel port. This card can be used in license, passport, credit card, ID card, bank card, health care, travel and entertainment cards and etc. In this paper, data on a card can be protected against unauthorized viewing.
