You can navigate to the following URL to check the multiple fingerprint reader and place the correct fingers on the reader while the URL is loading:
https://127.0.0.1:8442/api/vi/fingerprint/capture?index=<index_value>
The index_value can be one of the following:
1 indicates four fingers of the left hand.
2 indicates four fingers of the right hand.
3 indicates two thumbs.
The service returns the response in the following format:
{"Finger":x,"Image":{"BitsPerPixel":x,"BytesPerLine":xxx,"Dpi":xxx,"Height":xxx,"Image":"<fingerprintdata>","Width":xxx,"captureStatus":"Ok"}}
For example:
{"Finger":1,"Image":{"BitsPerPixel":8,"BytesPerLine":256,"Dpi":508,"Height":360,"Image":"<fingerprintdata>","Width":256,"captureStatus":"Ok"}}
where the finger represents the finger ID. Possible values are:
1 for the right thumb.
2 for the left thumb.
3 for the right index.
4 for the left index.
5 for the right middle.
6 for the left middle.
7 for the right ring.
