Biometric Smart Card Reader
The biometric technology is being harnessed in a very large way for security systems around the world. Devices like the biometric smart card reader are becoming the be-all-and-end-all in various security scenarios. They use the biometric principle of identifying humans through their bodily characteristics. In this case, information about the person is entered on a chip that is present in the card and then the information is enrolled onto a central computer system. When the person wishes to gain entry or avail of some other confidential services, all they have to do is to swipe the card on a special reader device. The reader will assess the information and then tally it with the information already present on the central computer system. Based on how well the information compares, the person will be either given entry into the area or denied access.
Biometric smart cards look almost like credit cards, but there is one basic difference. Credit cards have magnetic strips, which are visible as black strips on the rear of the card, just above the signature area. The biometric smart cards, on the other hand, have a complete microprocessor unit, which can be likened to a mini computer. The magnetic strip stores only one kind of information about the owner, which is likely the credit card number; but the chip in a smart card can save several kinds of information. A person who is validating a person's authority through a smart card can actually ask for a lot of identifying information about the person that is stored on the chip. In that way, smart cards are definitely more secure than credit cards.
There are methods in which biometric smart cards can be filled with biometric identifying information. A biometric smart card reader may allow that by having the person place their hand of finger on a reading area. The unique palm print or fingerprint of the person is then "read" by the reader and stored in its internal memory. This is unique information which cannot be duplicated by another person thus increasing the security that a smart card can provide. In some readers, this information can be juxtaposed with other kinds of information about the person such as their name, address, contact details, etc. This can be all filled onto an identification form on a central computer using biometric software. When an authority wishes to check who the person signing in actually is, they can link to their form and check out their details before authorizing them with entry permission.
The main use of the biometric smart card reader is security, but it is also being used in workplaces in a large way for time and attendance tracking purposes. But merging these swipe cards with timeclock functions, the actual time that a person works for in an organization can be recorded. This can be used during payroll time to make accurate calculations. It also saves the company from paying more for things like unauthorized overtime. It is no wonder that several Fortune 500 companies of the world are using these machines to better streamline their processes.
