METHOD OF OPERATING A SECURITY DEVICE |
摘要 |
<p>A lock has means (15, 16) for reading from a key (11) a binary encoded number. If the number read from the key is a predetermined number, the lock will store in a memory (19) a further number read from a further key applied immediately after withdrawal of the first key. The device will then recognise the second key, when applied subsequently.</p> |
