Biometric technology today and synchronization of access to systems

Time and attendance and scoring systems have evolved in recent years by traditional clock card last shot of biometric technology.
This may seem a bit 'extreme, but millions of people in mass society of people to be late, leaving early and what is known as' Buddy means "the clock for other people. Biometric access control is growing rapidly large organization such as banks, airports, etc. tend to set the trend for this type of technology and I'm sure that if you go to one of these, is a type of biometric scanner if it is pointing or control of access or simply to connect the computer on / off.
What is the problem of magnetic cards or pin numbers you might ask, can be copied or unlawfully obtained, where the biometric scanning is much more difficult to copy in fact almost impossible.

When people hear that you feel immediately biometric technology for fingerprint, but this is just one of many biometric systems.
Fingerprinting is the most common and least expensive to implement in any organization, the readers as IClock
the different readings to identify the point of ridges and valleys in fingerprints and then using a complex algorithm of the store as an individual code. In most cases, there is always a good practice to store more than one code for the fingerprint reader in only one case is cut a finger or a stain that can affect the reading.
Other types, such as the recognition of large drives requiring bulky. The terminal captures a three-dimensional image of the hand each time an employee puts his hand into the reader. The size and shape by hand are used to verify their identity. These types of systems are almost twice the cost of a fingerprint. Face recognition technology is growing, but requires a powerful computer is slow and not as reliable as other biometric technologies, but better than CCD cameras and software improves. Iris recognition uses infrared rays to examine the structure of the blood vessels behind the eye is also a biometric technology growing very fast. Iris recognition is a secure, but still needs to treatment is slow and powerful to play with a high failure rate is not very good for control of access, a lot of traffic.

With all the biometric systems the biggest battle of all during the execution will be like winning the trust of those using it. They need to be reassured that the data will be used only for what it is intended and is safe to use. This is probably the main obstacle to come with the introduction of biometric identifiers.

All of these biometric technologies have a place in today's security and business, but time and technology that the presence of fingerprints is more than enough because of the low cost and reliability, and most applications the safety of dual method fingerprint cards and offers a high level of access control. This is a map of media such as RFID (radio frequency identification) and verification of fingerprints must work together to gain access.

Using bar code technology is also widely used, but it has its problems, chief among them is the ability to clock in or out of other people clock Buddy "Obviously, this can be done if the biometric readers are used. On a positive side for the bar-code technology to other media is cost, because most of the barcode 3 of 9, EAN, Code 128, etc. can be printed on most laser printers and then laminated to create a map or clock the card work for very low cost. Other media can also be used for point-Buddy "is a magnetic stripe and proximity cards, but these media are more expensive than bar codes. Banda magnetism can be produced at home, but a costly encoder and printer are required to produce a map of good quality. RFID tags are purchased with an identification code already programmed, the advantage is that it is more difficult to copy the label and also the player does not need optical or any contact with the media to reduce a maintenance routine.

So what to choose? Biometrics can be as cheap and as reliable as other types of media, but it has its limits. Everyone has a place in today's world, if you need all the employees is the clock back and secure access to fingerprints low is the possibility of any support at low cost to produce or buy.
