Read the passage carefully. Government officials at national borders
Read the passage carefully.
Government officials at national borders look very carefully at passports and visas. They want to be sure that the people who are entering the country are not dangerous. They use technology to help them decide ters may enter the country. For example, when travelers enter the country, officials at the border check their computers for important information about these travelers. They can check if travelers have been in the country before and if they have done anything wrong. Officials also examine the traveler's documents to see if they are real. Some people try to cross the border without permission. They use fake passports or visas. Officials at the border can use computer technology to check whether these documents are real or fake.
Technology has been helpful in other ways, too. In the second half of the twentieth century, passports were the major form of identification for travelers. Now there are new forms of identification that use technology. One example is a machine that can read fingerprints. When travelers enter the country, they put their fingers on a machine that scans them. In other words, the machine takes a picture of the fingerprints and saves the picture in a computer. It can also send the picture to government officials who are far from the border. Those officials can compare the picture to fingerprints of many other people. If the traveler's fingerprints are the same as fingerprints of a dangerous person, the traveler may not enter the country. This technology is now in use at many airports all over the world.
One person's fingerprints are different from another person's fingerprints. Therefore, many countries use fingerprints as a good form of identification. However, it is possible to trick the machines that scan them. In 2008, a woman at a Japanese airport put tape on her fingers. The tape had another person's fingerprints on it, so she was able to enter Japan without permission.
As a result of these problems, some airports are using another part of the body for identification - the iris. The iris is the colored part of the eye. New machines can scan travelers irises and save the pictures. Several airports are already using this technology, including airports in London and Qatar. Irises work better than fingerprints for identification. The iris has hundreds of very small lines in it. These lines are unique. In other words, everyone's ins is different. Even twins have different irises, These new forms of technology have another advantage. They are fast. This makes lines at airports and borders shorter and helps travelers more quickly.
