Description Features: brand new and high quality Fingerprint module is an integrated fingerprint processing module integrating optical paths and fingerprint processing part, which has the characteristics of small volume, low power consumption and simple interface. High reliability, fast-recognition speed, good adaptability of wet and dry finger and fast-fingerprint search speed. The communication interface of fingerprint module is USB and UART. The fingerprint algorithm extracts features from the acquire fingerprint and represents the fingerprint information. The storage, comparison and search of fingerprints are all by operating fingerprint features. Fingerprint processing includes two processes: fingerprint registration process and fingerprint matching process (in which fingerprint matching is divided-into fingerprint comparison and fingerprint search two way). Specifications: Material:ABS Resolution: 500dpi Supply current: 60mA Supply voltage: 3.3V Window area: 15.3x18.2MM Communication Interface: USB/UART Length:Approx.48mm/1.89inches Note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
