People in the United States and in many other countries around the world are concerned with terrorism. Consequently, bio-metric applications are becoming more popular and necessary. Government and private organizations are developing and promoting many biometric applications such as fingerprint scans, hand geometry, and retinal scans to defend against terrorism. For example, airport security in the near future will use face scanning and fingerprinting. Visitors crossing national borders may be tracked with biometric information on large databases. Transportation employees will have their biometric information readily available to authorities in case of trouble.
Along with national security, biometric devices can have applications in everyday life. Medicare patients will eventually scan their fingers to confirm their medical information. Livestock can be identified with retinal scanning tied to a global positioning system to allow their movements to be tracked when necessary. Grocery stores and other retail stores may use biometric devices to prevent the forgery of checks and the use of stolen credit cards.
