ISO Fingerprin

详情

As an OEM module of fingerprint identification, it can meet the requirements of fingerprint identification system based on international standard exchange format (A)NSI/ISO very easily. Or USB communication interface for the UART, it as a work from the device, the host will send commands to control it.
Main functions: support standard: ansi**8 iso******2, fingerprint capacity: ***0 fingerprints (response time is less than 2.0 seconds), template size: ***4 bytes, recognize patterns: 1: n logo or 1:1 verification, automatic learning function, the fingerprint template, speaking, reading and writing features, fingerprint image read and write functions, is the uart and usb communication interface.
Fingerprint image characteristics: resolution: **0 dpi; Gray: 8, **6; Pixel matrix: **8 * **8  **6 * **8
Application: fingerprint access control; Fingerprint attendance; Fingerprint lock, fingerprint safe; Fingerprint POS terminals。
