Abstract: An apparatus and a method for providing access to a secured data or area includes at least two secure data modules which contain security data and other information and which belong to a particular security scheme and a dual module reader for reading data and permissions instructions contained on the secure data modules. The two secure data modules include an enabling module and an interrogatable module. The interrogatable module and the enabling module communicate with each other via a dual module reader. Communication between the two modules is allowed as long as the two modules are members of the same security scheme. A scheme is defined by suitable proprietary encryption keys for enabling communication and data transfer between the two modules belonging to a common scheme and for preventing communication and data transfer between two modules belonging to different schemes. The communication between the two modules provides an improved data security and access control system which eliminates the need for multiple passwords for various operations and also prevents problems associated with conventional access cards which are used in conjunction with passwords.
