The need to identify people is as old as humankind. People recognize each other by sight and sound. However, in today s complex society it s impossible to personally know everyone.
Biometric devices automate the personal recognition process.
Each of us is unique from every other human being. We also have unique physical characteristics, such as hand shape, blood vessel patterns and fingerprints. Biometric devices measure and record unique human characteristics for automated comparison and verification. Today's biometric products evolved from the electronics and computer revolution. Modern detection technologies allow precise measurement and comparison of unique human characteristics.
