Biometric authentication is considered useful technology as it reduces the number of passwords, prevents theft and is easy to use. Many government agencies, multinational organizations, institutions, banks and hospitals are embracing the use of biometrics. Research suggests that people are more positive about modern biometric technologies than traditional security systems. One advantage is that it provides various types of solutions that are almost impossible to hack in comparison to passwords. Thousands of employees can be tracked in a large company with only one biometric device and software. Nobody has to remember their password, they just have to show up. It saves time and the person only needs to put a finger on the device or look at the retina device to get through the system. The combined cost of biometric software, computers, programmers, server and other equipment is a large amount of money. Fingerprint scanners are unhygienic because they are used by many people every day. It is used in various places such as schools, airports, offices, banks and libraries, which means verifying identification is quick and convenient.
