Clock Cards

Time and attendance systems and clock have moved in recent years some of the traditional punch clock cards to the latest biometric technology.
This may seem a bit extreme but companies loose millions of people arriving late, leaving early and what is known as â € ~ Buddy Clocking € ™ people watch for others. Biometric access control is growing rapidly larger organization, such as banks, airports, etc. tend to set the trend with this type of technology and I'm sure if you go to any of these are in some type of biometric scanner if signing or access control or simply to record the equipment on / off.
Whata € ™ s wrong with magnetic cards or PIN numbers that might ask, they can be copied or obtained as disguised as a biometric scanner is much more difficult to copy, in fact almost impossible.

When people hear thought biometric immediately from the fingerprint technology, but this is just one of several biometric systems.
Fingerprint is the most common and least expensive to implement in any organization, the readers, as the iClock
take several readings point pins on the ridges and valleys in the fingerprint and then using a complicated algorithm store these as an individual code. In most cases, it is always good practice to store more than one code in the fingerprint reader only when making a cut finger or a stain that can affect the reading.
Other types, such as hand recognition readers require large bulky. The terminal captures a three dimensional image of the hand each time the employee places his hand on the reader. The size of the hand and shape are used to verify your identity. These types of systems are almost double the cost of fingerprint systems. Facial recognition technology is increasingly But requires treatment by powerful computer is slow and not as reliable as other biometric technologies, but is improving as a CCD camera and software improvement. Iris recognition, which uses infrared to look at the pattern of blood vessels in the back of the eye is also a biometric technology of very rapid growth. Iris recognition is a secure system, but requires more powerful processing and is slow to read with a high failure rate is not very good for access control with a large amount of traffic.

With all biometric systems for the greatest battle in the implementation of these is how to gain confidence of people who will use them. They must be sure that the information is only used for what is intended and is safe to use. This is probably the most barrier over time to introduce biometric readers.

All of these biometric technologies have a place in today € ™ s safety and € ™ s business but time and technology of fingerprint attendance is more than enough because of low cost and reliability and most security applications of the dual method of fingerprint and the card offers a very high level of access control. This is where a media card such as RFID (identification radio frequency) and the fingerprint must match together to gain access.

Using barcode technology is also widely used, but has its main problems is the ability to watch other people inside or outside the â € ~ Buddy clocking € ™ obviously this can not be done if used biometric readers. First, more about barcode technology to other media is cost, as most codes 3 of 9 bar, EAN, Code 128 etc. can be printed on most laser printers and then laminated the creation of a clock card or work card by a very small cost. Other media can also be used to â € ~ Buddy clocking ™ € are magnetic stripe and proximity cards, but these media are more expensive than bar codes. Magnetic strip can be produced at home, but expensive encoder and printer are required to submit a card of good quality. RFID tags are purchased with an identification code already programmed into it, the benefit of this is that it is more difficult to copy the label and also the reader does not require any optical or contact the media to reduce any type of routine maintenance.

Then, Which one? Biometrics can be as cheap and as reliable as other types of media, but has limitations. Each has a place in today € ™ s world, if all you need is to clock employees in and out and low security access, fingerprint is the low cost option with no means to produce or purchase.
