FAQs About CAMA-SM25 OEM Fingerprint Module
1. Does the SM25 support Windows, Android or Linux system?
Answer: Yes, SM25 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 SM25 support read and write fingerprint template ?
Answer: Yes, SM25 optical fingerprint module support read and wrtie fingerprint template . If you need, you can use Read Template Command to extract the fingerprint templates from SM25 module and use Write Template Command to write the fingerprint templates into SM25 module from other place.
3. Does the SM25's template data compatible with other manufacturer's fingerprint template data?
Answer: No. SM25 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 3,000 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 SM25 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 SM25 optical fingerprint sensor module can work with Arduino development kit?
Answer: Yes, the SM25 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
