Hi @Ali.Alhajj , I’d like to advice you to make the registration of the fingerprint with one of the C2 Slim devices. You can do it by CrossChex: add a new user and select “Network” option for registration of the fingerprint. When it’s done distribute this user to the other devices and check reading quality. ---

Hi @Tibor We did registered 5 new users on C2 Slim And no difference, you need to swap your finger at least 3 times and the fourth one accepted Note: I have 10 years experiance on Access control systems I tried many brand ( Virdi, suprema, Chiyu, etc…) Through my experiance the best finger module is Suprema never miss any finger We are always installing Anviz Face series and its our first time using finger series My thoughts, Finger module need to be upgrade and beter to consider using Suprema finger module OEM Model SFM-5020 ![Screenshot_20220822_123828](https://us1.discourse-cdn.com/flex020/uploads/anviz/original/1X/df4c0ce5dc43c60c17a7d9716161553e012a36fb.jpeg) ---

Salam @Ali.Alhajj , I recommended this solution because it helped us earlier in case of a combo installation of C2 Pro and M7. About your note: we’re dealing with Anviz products for almost a decade (and 30 years with access control systems). We also experienced unreliable operation of fingerprint detection. Other solutions what worked at our installations: resetting the device to factory defaults, firmware upgrade, changing the power supply unit, using a LAN noise filter. ---

The C2 Slim and C2 Pro adopt the same fingerprint sensor (AFOS518). ![image](https://us1.discourse-cdn.com/flex020/uploads/anviz/original/1X/a477170568c2e49d1b2a7940a1e1d91807892cd1.jpeg) And please help us to check the C2 Slim’s fingerprint image via the C2 slim’s webserver. Step 1: Log in to the C2 Slim’s web server by default IP address in the browser ![image](https://us1.discourse-cdn.com/flex020/uploads/anviz/original/1X/f558651b4767d0cba0d587f5088be8bdf4463c3a.png) Step 2: Modify the link address in the browser: Such as [http://192.168.0.218/test.html](http://192.168.0.218/test.html) to activate “fpSave” option as “Yes” and click the “Submit” button. ![image](https://us1.discourse-cdn.com/flex020/uploads/anviz/original/1X/e09f00e6b4efabc7ce757fe3fb0668db9ee7da17.png) Step 4: Click the link to the fingerprint image display page. ![image](https://us1.discourse-cdn.com/flex020/uploads/anviz/original/1X/18e2cca041f45879bd09f90b998875c454180d37.png) Step 5: Press the finger on the C2 Slim’s sensor then click “refresh bmp file list” which will display the image to check the Image quality of fingerprints. ![image](https://us1.discourse-cdn.com/flex020/uploads/anviz/original/1X/76db960421474265fa2591aff695a7665c9f2c7e.jpeg) This way only check the Image quality of fingerprints.
