Q:

What are the advantages and disadvantages of using Biometric readers, PIN codes or Proximity cards?

A:

Biometric systems are usually more secure than the standard Proximity mean. A Proximity card can be lost or stolen and a PIN can be announced or viewed. Biometric systems are usually more expensive than PIN or Proximity systems for the following reasons:

• Hardware such as Biometric readers are likely to cost more than PIN or Proximity readers

• The Biometric software usually requires a license which is purchased upon initial setup

• There are usually ongoing costs such as Annual license fees with Biometric systems

The big advantage of Proximity over Biometric technologies lies in its simplicity. There are no moving parts, no mechanical wear, no slots, and no read heads to maintain. The reader can be concealed inside walls or special enclosures and poses even fewer problems when surface-mounted because it has no opening with which to jam or tamper.
