Well you never seen the fiction movies ... ? ? ?
Where the person itself use a biological identifier ? Like his own finger digital ? His own eye ?
This scifi technology its possibly the next step into introducing the mark of the beast through laser and scanner not through biochip ! You never gonna to the supermarket and forgot your wallet on your house ? This will no longer be a problem , you can simply be scanned and the debt will be already paid in seconds ... you get food , parfum , anything , and just get scanned quickly and go out of the market. .. much more practical . Why use a credit card ore wallet if you can type your number , and put your finger on the screen and get out of the market faster ?
It is called BIOMETRICAL technology that send information according to your biological information.
In information technology, in particular, biometrics is used as a form of identity access management and access control. It is also used to identify individuals in groups that are under surveillance.
fingerprint, face recognition, DNA, hand and palm geometry, iris recognition, which has largely replaced retina, and odor/scent
typing rhythm, gait, and voice.
Biometric technologies have been found in a number of popular cinema released films. This alone has created an interest, from general consumers, as a means of identifying ones self. In 2003 both X-Men 2 and Hulk used biometric recognition technologies in the form of hand access control in X-Men 2 and fingerprint access in Hulk.
It wasn't however until 2004 when iRobot was released, staring American actor, Will Smith, that biometrics were truly showcased.
Starting in the early 2000s, thousands of schools throughout the world have begun to establish biometric systems. A number of reasons are given for such practices, including struggling against truancy, replacing library cards or meal cards by fingerprinting systems, etc. Opponents of school biometrics have lifted up privacy concerns against the creation of databases which would progressively include the entire population.
