Security Overview - Access Control
Biometric is becoming more popular in access control due to its
ease of use, higher security and no ongoing costs like some card
systems. It is highly accurate but is further enhanced when used
also in combination with a secondary authentication method. Remote
Entrance Management can manage the situation should there be an
occurrence of authentication failure.
The good old fashioned numeric keypad is here to stay at least
for the foreseeable future. Of course it is not very secure as
security codes can easily be passed inside or outside an organization.
It would operate more efficiently when used in conjunction with
another more secure means of access control.
A magnetic card works with an electronic or electromechanical
device to replace or supplement mechanical key access to a building
or an area within a building. Of course cards can get lost which
then causes extra work in terms of the whole issuing procedure
and will also incur ongoing charges.
The fastest growing technology for card access control applications.
The proximity technology reader constantly transmits a low-level
fixed radio signal that provides energy to the card. When the
card is held at a certain distance from the reader, the radio
signal is absorbed by a small coil inside the card and powers
up the card's microchip, which contains a unique identification
code. Once powered, the card transmits the code to the reader.
Access is completed in microseconds. Proximity readers do not
have any moving parts, which mean they are virtually maintenance
