Biometric fingerprint technology is the most widely used technology in the world to identify individuals. Depending on the concept, there are optical, capacitive or multispectral fingerprint sensors. The optical sensors are primarily suitable for log in at the computer and in small or medium-sized businesses. A higher security is offered by capacitive sensors, which are also used by public authorities, for example. The multispectral sensors offer the highest security and can also be used due to their technology in areas where optical or capacitive sensors are used.
