DBmatch not working for me #2

Closed Churkabesina closed 9 months ago

Churkabesina commented 9 months ago

Hi! I have a zk9500 device and I work with python, so I came across your library. I need to save my fingerprints in the database and get them back. I register the fingerprint through DBmerge and put it in my database (for emulation, I just use writing bytes next to it in a file). Next, I want to compare the fingerprint in the database with the attached finger and the DBmatch function shows that the fingerprint in the database does not match the attached one. I am attaching a simple code of my actions for understanding. What am I doing wrong? simple_example

DBMatch is used to compare two fingerprints. You used it to compare a fingerprint and a result of merging three fingerprints python_bytes.

that said, DBMatch is used just to make sure a user enters the same fingerprint n times by matching each fingerprint with the latter. i.e., you may do something like DBMatch(templates[0], templates[1])

please refer to the documentation for more info or have a look at this example.
