Abstract: The present invention is a method for monitoring equipment. A computer having an enclosure defining an enclosure space is initially provided. Disposed within the enclosure space is a central processing unit including a memory and an arithmetic logic unit. The computer is provided with communication means operably connected to the central processing unit for permitting communication between the central processing unit and a peripheral device.

Abstract: The present invention relates to an electronic transaction security system for executing an electronic transaction between a transaction or having an individualized transaction identification code and a transactionee. A transaction initiation request is inputted into a transactionor computer associated with the transactionor. The transaction initiation request requests the electronic transaction and includes the transaction identification code. The transaction request is transmitted electronically from the transactionor computer to a transactionee computer associated with the transactionee. In response thereto, the transactionee computer transmits electronically a verification request requesting validation of the transaction initiation request to the transactionor computer. The transactionor computer receives the verification request and transmits electronically a verification response indicating one of a valid transaction and an invalid transaction to the transactionee computer.
