Description

Fingerprint readers belong to a wider family of biometric security methods. TI designs help you design in a fingerprint reader solution whether that solution uses capacitive, optical, pressure or thermal technologies. Fingerprint readers use biometric information, specifically a fingerprint, as the input. The fingerprint acts as a form of authentication.

The most common fingerprint sensor solution first illuminates the print with a laser or LED light and then captures the image using a CCD or less expensive CMOS sensor. Fingerprint sensors are typically self-contained modules that include an analog to digital converter to translate the analog information into a digital data stream. Resolution, dynamic range and pixel density are factors that contribute to the image quality and influence the accuracy of the sensor.

TI has power solutions and interface (for example, Ethernet or RS-485) devices to fit fingerprint biometric readers. For systems that require two-factor authentication, TI offers reference designs for a touch on metal keypad or RFID/NFC receivers. A wireless fingerprint system may use TI’s low power RF devices (Sub 1-GHz or 2.4-GHz) to connect to a host or mobile device as well as motor drivers for the lock solenoid.
