Safety and security considerations are as old as the civilization and humans always wanted to protect their assets from the anti-social elements like thieves, infiltrators and plunderers. These dimensions are still very potent; courtesy to the rising prosperity coupled with the rise in crimes of all types. However, apart from these fundamental dimensions relating to security and safety, there are newer ones also that have emerged because of the advanced makeup of the socio-economic matrix around the world. Companies and enterprises require security of their assets and the staff and also want to prevent the infringements from the individuals who are not eligible or certified by them. With such dedicated significance of security, newer methods have been developed and are being continuously refined. Biometrics and RFID based access control system can be counted as the frontline technologies that rely on high-quality electronics and deliver fool proof security applications. These truly ensure the new future in access control!
The biometrics –
Biometrics, as the name suggests combine the components of bio with electronics in a manner that distinct signatures are read and analyzed for the purpose of identification and hence access also. The most common types of biometric signatures that are being used include the fingerprints, iris scans, heart beats and facial recognition. These attributes differ from individual to individual and cannot be same under any circumstance. Under this premise, appropriate technology has been developed to read these attributes and compare them with the existing database for the purpose of authentication. The leading attendance monitoring system supplier in India says that biometrics technology is today the most demanded by the companies that want to install smart employee management system.
RFID or the ‘radio frequency identification’ is the newest technology that relies on the electromagnetic radio waves that are transmitted and received between the tags and interrogator receivers. Upon matching, an authentication request is responded positively in the form of ‘access’ for the seeker in any ambiance or through any passage. This technique requires the establishment of a two-way mechanism wherein the receivers and RFID tags communicate either proactively or upon specific request (when activated) and a reading of the embedded information is done in a smart way in the backend servers that handle security. Leading access control system software supplier of India says that depending upon the nature of the security sought there could be PRAT (passive reader active tag), ARPT (active reader passive tag) or ARAT (active reader active tag) types of mechanisms.
The biometric and RFID combined –
The last few years saw active use of both the technologies – biometric and RFID in a combined manner to generate high level access security solutions; particularly in the corporate ambiences where sensitive information/product is abundant and needs to be guarded. The notable advantage of the combined use of these two technologies is the ‘access by exception’! RFID and biometrics access control system supplier says that by coupling the two functions, the failure in one technology due to any reason cannot be held as the absolute fault and would be faltered by another technology. Thus if there is a mismatch in the access response by any of these technologies then a person stands sorted for investigations.
