Abstract: A cellular phone call management system using a microprocessor-controlled remote card reader interface for a cellular telephone system to record calls onto a card as they are placed or received. A microprocessor reads information from a card placed in the remote card reader and ensures the card is valid. The cellular telephone's transceiver logic bus is monitored to determine the transaction information of a call as it is placed or received. After the call is completed, the call transaction information is recorded on the card. When all calls are complete, the card is placed in a host card reader attached to a host computer where the call transaction information is read from the card, processed, and written to a host storage device. The call transactions may then be analyzed and reports may be generated and printed by host computer software.

Abstract: A secure computer controlling access to internal devices via an integrated card reader. A microprocessor-controlled card reader interface logically connected to the CPU of the computer reads and writes information from and to a card placed in the card reader and performs additional functions in response to commands received from the CPU. The boot ROM of the computer is programmed to start execution from a program logic device which runs a verification program to verify the authenticity of a user. Upon a valid user card being placed in the card reader, one or more questions are read from the card and displayed to the user. The user's responses are saved and compared to the correct answers stored on the card, and if the responses match the correct answers, a power control circuit is used by the CPU to turn on power to computer peripherals the user has been authorized to use.The system additionally provides for a method of initializing and authorizing a user card with a security administrator card.
