Please refer to the attachment to calculate how many fingerprint templates and users you can store in the device.
Note that if you store more users in the device, the authentication time will also take longer.
This difference in authentication speed is much more noticeable with 1st generation devices (BioEntry Plus, BioEntry W, BioLiteNet, etc.).
Note In BioStar 2 the limitations for fingerprint per user on the device are same to all devices: 10 fingerprints.
