The most accurate type of Biometrics is Retina Scanning. It is almost 100% accurate. Along with the Iris, you can't change the information held in the patterns in your eye. But people can wear colored contacts, which would throw off the Iris scanning process. So in conclusion, the Retina Scanning is most accurate.
A fingerprint reader is the most common type of biometric device. It can be found on latops, PDA's and even memory sticks. Fingerprint readers are becomming very popular.

Biometrics are helpful tools for security and identity verification. They are especially useful to establish the identity where a person might be stranger to the other, for example huge databases like banks. Biometrics identify on the basis of features unique to an individual, like signature, finger print, iris etc. These are difficult to forge. Biometrics used in home doors do not require carrying a key, or the fear of the key getting stolen. Biometrics are also used to identify criminals and determine their identity.
Applications of biometrics are broadly classfied into three categories: 1. Forensic Applications; 2. Government Applications and 3. Commercial Applicatuions
Fingerprint readers, facial recognition, speech recognition... anything really that can be used to uniquely identify a person, in the way of the physcial structure can be used for biometrics.
