Here's a question for the real professionals in this group.
What does it take to qualify as a "lock" ? Do the more or less toy handcuffs sold at Spencer Gifts have a "lock" or is that merely a latch ? Why do "locks" with bolts that ride on springs even in the locked state qualify, along with dead bolts ? Is it the "authentication" mechanism, the requirement of a key or combination that makes the difference, regardless of how easily spoofed the key might be ? In cases of biometric devices, are they still "locks" if the protection is provided to information systems and there is no physical component barring entry at all ? Is the child proof cap on a plastic prescription drug bottle a lock, with a combination of simply pushing down before one turns it ?
Just curious...
