Access control is often a system enabling authorities to control use of areas and resources inside a given physical facility or computer-based information system. Access control is, actually, a typical, everyday phenomenon. For example, a lock on the car door is essentially a kind of access control. The PIN over a bank's ATM method is another way of access control. Even nightclub bouncers, standing in front of your door, are another illustration of (perhaps) a much more primitive mode of access control. Using an access control mechanism is essential when persons seek to secure confidential, important, or sensitive information and equipment.

In 1981, car makers started assigning a unique, 17-character code to each vehicle that is built, which is often used for assorted purposes, but mostly for verifying the legitimacy of vehicles. Governments and law enforcement agencies apply it to identify stolen vehicles, and motorists demand it after they take their cars to some mechanic, plus its useful when choosing a second hand car, so that you can operate a vehicle history report. The insurance industry often uses vehicle identification numbers, too. VINs are generally engraved on aluminum plates, cast or stamped, like a bar code, or perhaps label form, plus they can be found on the car's steering column, doorjamb, driver's door, passenger side door, dashboard, as well as in a vehicle's maintenance book and title.
However, science and technology are two different social cultures, and the differences between them are obvious. The basic task of science is to know the world and find it, thus increasing the intellectual wealth of mankind. The basic task of technology is to discover the world and invent it to create the material wealth of mankind and enrich the spiritual and cultural life of human society. Science answers questions about "what" and "why"; The technology answers the question "what to do" and "how to do". Therefore, the results of science and technology are different in form. Scientific achievements are generally expressed as concepts, laws, papers and other forms. The technical results are usually in the form of process flow, design drawing, operation method and so on. Scientific products are generally not commercial and technological achievements can be commoditized. Modern technology has a strong utilitarian and commercial color.
