Access Control
Are you still using 4000 year
old technology? (See Locks Throughout History,
at left.) Up until 30 years ago, locks used metal
keys. Although simple and reliable, most of these
keys
could easily be duplicated and the locks easily
picked. If a key was lost or if an employee was
fired, it
was
expensive
to rekey the locks to prevent unauthorized entry.
In
the seventies, locks designed for plastic punch cards
allowed for much better control of keys. Hotels
quickly
adopted this safer technology (see Is
Your Building A Lawsuit Waiting To Happen?)
Now, there are dozens of secure and
economical designs to control and monitor who has access
to your locked areas. Non-duplicating keys, keypads,
stand alone units, magnetic cards, bar code cards, data
chips, proximity cards, finger readers, hand readers,
retina scan readers, face recognition readers, voice
recognition, are just a few examples of such systems.
An access control system can help track
employees or vendors as they enter or leave the premises.
In addition, it can limit the times they have access
to your premises such as after hours, non-working hours
or holidays when you are closed. For example, if an
employee quits or is fired you can easily lock them
out instantly without having to depend on a locksmith’s
schedule to re-key the premises.
You can issue temporary access cards
to cleaning and service people without fear of improper
duplication
or of people leaving the site without returning your
keys. Biometric readers are an enhanced level of security
for sensitive areas in your business and are a lot
less
expensive than you might think.
There are many factors to be considered,
from cost and ease of use, to how much security you
really need. For instance, a research lab might warrant
an FBI-grade eye scanner, but for your general office
staff, a proximity card would be faster and more
convenient. In general, proximity cards (sort of like
your cars EZ-Pass) allow the fastest flow of people,
with conventional keys and various cards close behind.
Biometric readers can take from 3-10 seconds per person,
which is fine for specialty areas but not high traffic
(note that if combined with a smart card or other ID
device, the computer can make a verification match
much
more quickly than if it has to search the whole database).
Here is a very brief look at some options; then call
