"Fingerprint Reader" - How can we increase the security of protecting our valuable property? One method is to use biometric devices, such as a fingerprint reader, which until recently was only found in forensic medicine to help identify suspected criminals, and which is now also used to secure property. How does the fingerprint reader work? In the fingerprint scanner, a system of properly arranged LEDs sends light to a glass, plastic or transparent surface, on which a finger is pressed. The quality of the fingerprint can vary with each application, depending on the degree of contamination of the finger, the test surface of the fingerprint or the colour and intensity of the light in the immediate vicinity of the reader. The light emitted by the LEDs is reflected on the surface of the fingerprint scanner and is received by an image sensor based on CCD or CMOS technology.

S0143
This fingerprint scanner (as608-optical reader) is ideal for Arduino or Raspberry thanks to its small size and low power consumption. It has a simple interface, high reliability, good adaptability of wet and dry fingers, fast recognition speed and also in fast fingerprint search. Storage capacity of up to 120 fingerprints in its internal FLASH memory.
SP036
This fingeprint scanner from ADH-Tech combines a highly precise fingerprint sensor module with an onboard MCU and UART interface enabling trivially very connection to any project.
The scanner independently reads and analyses the fingerprint thanks to an MCU algorithm that can send a converted digital signal to a peripheral serial interface for a data read. The onboard MCU algorithm enables operations such as for example a fingerprint enroll.
