摘要
A security system in which personnel are permitted access at certain locations on the basis of data magnetically encoded on a card inserted into the system by the personnel. Access is also limited on the basis of keyboard data entered at the remote location by personnel wishing access. The keyboard data required for entry is a permutation and combination of the data on the employee's card, the particular combination and permutation required at each remote location being independently programmable by switches accessible on the inside of the remote security system.
