A computer security device and method for controlling access to computers using radio frequency (RF) cards are disclosed. The computer security device includes and RF card detector for detecting a user identification (ID) stored in an RF card, and an access controller, coupled to the RF card detector, for comparing the user ID detected by the RF card detector with a prestored user ID, and controlling communication between the computer and the input device of the computer based on the comparison results, so as to control access to a computer. The method includes the steps of detecting a unique ID stored in the RF card, first comparing the detected ID with an ID prestored in the computer security device, second comparing the detected ID with an ID prestored in the computer, and controlling communication between the computer and the input device of the computer based on the first and second comparison results. |
