Biometrics, or Door Card Reader the recognition of the identity of someone based on a biological aspect of a person, is actually a very old technology. We use biometrics everyday when we use the ‘computer' that we call the human mind: for example, when we recognize someone by looking at his or her face, or when we check a written signature against what we trust to be a bona-fide copy of a signature. The futuristic feel of biometric technology comes about when we match the traditional biometric approach with the new capabilities that we have in electronics. Now we can use electronic devices to make biometric judgements about the authenticity of a person—that is, "is person x who they say they are?" Since the information and digital age is upon us, the technology has come about that makes authentication exceptionally accurate, and potentially a much more reliable means of authenticating a person than traditional, human-judgement based biometrics.
Experts in authentication technologies usually classify the criteria that are used to verify someone's identity based upon a few different categories. "What you know", or W-Y-K, is one form of authentication: a common version of this occurs when you give an electronic bank terminal your PIN (or Personal identification number). "What you have", or W-Y-H, is another criterion, and this refers to the possession of some identifying object such as an identification card or passport: but you could even consider a simple door key as a kind of W-Y-H proof of identity for allowing access into a private or controlled access property. Biometrics, according to this scheme of classification, would generally be termed "What you are" or W-Y-A. It is the presentation of a physical aspect of yourself that is quite uniquely and individually you, in order to obtain authentication.
Electronic access control (EAC) over properties based upon biometrics is not a new technology, having been around for decades—and it has taken on many forms. Hollywood movies have long depicted high security installations that use finger and handprints, eye (iris and retina) scans, facial and voice recognition and so on, in order to verify identity. Of course, media typically depicts the technology as being used by spies, high-tech corporate installations, the ultra-rich and other elites of society: possibly to protect priceless assets and information, or to prevent espionage and treason. Only recently has it become an exciting time for the rest of us, technologically speaking, as "the digital age" has brought electronic biometric technology to a quality standard and a price that is within the reach of the average consumer.
The newest consumer item is a biometric access control device that scans a person's fingerprint in order to allow access to a property, or even to a vehicle. High-tech industry commentators are seeing biometrics as the new emergent technology that will eventually replace, or at least be offered alongside all other forms of access control (such as keys, or electronic access control devices based upon PIN code keypads, magnetic card swiping, or Radio Frequency ID (RFID) tokens/key-fobs). One of the principle reasons for this is that the biometric device potentially offers an entry control solution that is free of the typical problems that beset older technologies. That advantage might be simply avoiding that horrible feeling you get when you are standing at your front door and can't find your keys, or when you have so many PINS in your head that you can't remember the right one to gain access to a property. Maybe it is when the so-called magnetic stripe card has lost its magnetic properties, or you have lost the card; or when a RFID key-fob has run out of batteries, is stolen, or simply just fails to communicate to the lock. Biometrics could be advantageous for those that have physical difficulty with the operation of any of these older technologies. With biometrics, all you need is a finger, placed upon a small screen that scans the fingerprint, and then you then gain access to your property.
This is a relatively new technology for the consumer marketplace, and so if you are thinking of trying a biometric access control device, it pays to be cautious in terms of the unit that you select. What do you need to look for? Knowing this might mean the difference between having a new and more amiable relationship with your front door, or one which ends with a lot of frustration, as you imitate Jack Nicholson in an axe-wielding duplication of the "Here's Johnny" scene from the movie "The Shining". Hence, the following are some things to think about when selecting a biometric device.
N&R technology supplies many different styles of RFID key fob. And with kinds of material for the RFID key fob. Including ABS, plastic, PVC, PVC+EPOXY, Leather, Metal material.
The RFID key chain which we provide is water proof and dust proof. It is durable use and easy carry. They can be printed 1-2 silk-screen logo or laser number on the RFID keyfob. And if you need to have nice designing image on the RFID key fob (full color printing). You can choose the PVC material keychain or Jelly tag ( EPOXY key fob).
