FAQs About CAMA-SM2510K Optical Fingerprint Module

1. Does the SM2510K support Windows, Android or Linux system?
    Answer:  Yes, SM2510K optical fingerprint module can work with these operating system.  Actually SM2510K optical fingerprint module is an OEM embedded optical fingerprint module, it can work with any operating system based on our command protocol.

2. Does the SM2510K support read and write fingerprint template ?
    Answer:  Yes, SM2510K optical fingerprint module support read and wrtie fingerprint template . If you need, you can use Read Template Command to extract the fingerprint templates from SM2510K module and use Write Template Command to write the fingerprint templates into SM2510K module from other place. 

3. Does the SM2510K's template data compatible with other manufacturer's fingerprint template data?
    Answer: No.  SM2510K optical fingerprint module only support CAMABIO fingerprint template format, it does not compatible with other manufacturer's fingerprint template format.  

4. What should we do if we need more than 9,998 fingerprint users ?
    Answer:  We suggest you to build a server system by our CAMA-2000 Desktop USB fingerprint scanner and store the fingerprint templates on the server.  And the terminal device with SM2510K only for capturing fingerprint and transfer the fingerprint template to server to do verification and then return the result to terminal device. 

5. Does the SM2510K optical fingerprint sensor module can work with Arduino development kit?
  Answer: Yes, the SM2510K optical fingerprint sensor module can work with Arduino board.

6. Can you provide library SDK for Arduino?
Answer: Yes, we can provide a simple SDK for Arduino UNO development kit 

7. Does SM2510K's size compatible with SM25 fingerprint module ?
Answer: SM2510K's optical fingerprint sensor is totally compatible with SM25 optical fingerprint sensor. But SM2510K have a extra PCBA board. So when you design your product, you should leave space for this PCBA board. 

8. Does SM2510K's communication protocols and fingerprint template compatible with SM25 fingerprint module?
Answer: Yes. SM2510K's communication protocols and fingerprint template are compatible with SM25 fingerprint module.
