Three Types of Biometrics

There are several types of biometrics

There are several types of biometrics. Depending on the system, biometrics is divided into three types:

1. Systems that store data directly on the appliance.

With this system, the data will be stored on storage media that is in the detectors. If at any time the machine must be reset or returned to the starting position, then the existing data may be lost. As the result, the workers have to re-input.

If the workers enter much data, there will be very troublesome. It is different when the data that is entered is not too much. Biometrics with this system is suitable to be implemented on a particular tool that is not used by many people or to protect a special room, which is also not accessible by many visitors.

2. Systems that store data on the network.

The second system uses network to store its data. The second system is very effective for applications that are used for many users. For example: the system for the data of employees or students absent.

The physical form that is displayed by the device also does not need to be too big. It is because the data will not be processed directly on the appliance, but it will be sent first to a new network and then it will be processed and stored. Indeed, this system requires a long time. Fortunately, it is quite effective for large data. It will not be exposed to the risk of lost data during the process of resetting the device should be done.

3. Systems that store data on a chip.

This latter system uses additional media, such as chip to store data of the ID owner. So, to use this system, one must take it. This latter system will be very effective to be applied if the users are many or the appliance is put in public places. For example: for security at ATM machines or just as an ID entry in a building.
