If you want to access by fingerprint, you should collect the fingerprint data via the fingerprint recorder first, and then apply the fingerprint data and parameters (e.g., fingerprint ID, type, and so on) to the fingerprint module of access control device and link the fingerprints with the card for getting the access permissions.
Make sure you have called NET_DVR_Init to initialize the development resources.
Make sure you have called NET_DVR_Login_V40 to log in to device.
Make sure you have collected the fingerprint data, refer to Collect Fingerprint Data for details.
