1. Integrated image collection and chip algorithm together, all in one2. The flexibility to adapt to the conditions, whether dry, wet, light and old, all have a high recognition rate3. Main application areas: can be embedded in end products such as: access control, attendance, safe deposit box4. The R503 fingerprint module has a built-in algorithm chip5. The line spacing of the interface is 1.0mm and the length is 20cm. The thread diameter is 25mm, easy to install.
