FAQs About CAMA-AFM3 Capacitive Fingerprint Module

1. Does the CAMA-AFM31 capacitive fingerprint module support Windows, Android or Linux system?
    Answer:  Yes, CAMA-AFM31 capacitive fingerprint module can workd with these operating system.  Actually CAMA-AFM31 capacitive fingerprint module is an OEM optical fingerprint module, with our command protocols, it can work with any operating system.

2. Does CAMA-AFM31 capacitive fingerprint module support read and write fingerprint template ?
    Answer:  Yes, CAMA-AFM31 capacitive fingerprint module support read and wrtie fingerprint template . If you need, you can extract the fingerprint templates from CAMA-AFM31 by the read template command and wrtie fingerprint template into the CAMA-AFM31 from other place by write template command. 

3. Does CAMA-AFM31 capacitive fingerprint module is using original FPC1020 capacitive fingerprint sensor ?
    Answer:  Yes, CAMA-AFM32 is using original FPC1020 capacitive fingerprint sensor.  It's performance is much better than the other capacitive fingerprint sensor in the market. 

4. Does CAMA-AFM32 capacitive fingerprint module have waterproof function ?
    Answer:  CAMA-AFM32 only suit for indoor  working environment .  It is not waterproof.  If you need waterproof functions, we suggest you choose our SM series optical fingerprint modules .
