Science fiction every time approaches more, to become a real business. In this way, already the routine identification of employees, visitors, users of credit cards is possible and others; by means of biometric information, as fingerprints, face landlords and the voice recognition. The price of the technology, needed to scan and to read these qualities, is reduced day to day; reason why more and more consuming they accede to these devices. Thanks to this, the technologies that cost 3 thousand dollars in 1999 today cost only 100. Inc. the Identix company, for example, sells readers of digital tracks that are connected to ports of computers, plus necessary software, by a price similar to which a pair of sport shoes costs. This way, by less than 200 dollars it is possible to be acceded to an apparatus of much utility. In the same way, the monitoring systems of rainbows are cheaper at present, due to the economic cost of the hi-res Chips, that are used in their cameras.
A consequence of this, a system of I scan of rainbow that cost 15 thousand dollars, in the middle of the ninety, costs 300 dollars at present. As a result of the reduction in price of these systems, in the United States, it is hoped that in next the three years, more than 20 million people they begin to use identification cards, with biometric data including. Additionally, also one hopes that 60 million foreign visitors, who will enter in the future the United States, load with himself biometric passports. One of the most promissory areas of the biometry is related to the prevention of the identity robbery, which is bound to other types of frauds. Also it is hoped that the biometry gives a hand in financial transactions, helping to that the consumer gains confidence against the electronic commerce. For it, it will be counted on methods that can make sure that a person, whom she buys by Internet, is the holder of determined account. The biometric cards, of identification, already they are used in order to help businesses to mount systems, for the access control, doing to a side the systems of passwords. Of this form, in some countries already it is possible to be seen facilities like warehouses of banks, laboratories and computerized data bases; in that this technology is used. In both last years, many corporations have begun to invest strongly in biometric technology, as you scan of digital tracks, with the purpose of to make sure that only the personnel with permission, makes use of enclosures or systems of computer science.
