There is a certain number of people whose fingerprint lacks the necessary information to be able to register it in a biometric system. In these cases, it is recommended to use an alternative technology. Fermax has developed the Combined Keyboard and Fingerprint Reader. Biometric fingerprint access reader with capacitive sensor. Identifies the user through his fingerprint (unique and unrepeatable characteristic for each person). Fingerprint reader that through a jumper configuration (JP1) that incorporates can work in an autonomous or centralized system. Configuration as AUTONOMOUS -> Capacity (number of users), according to the chosen operating mode: (1) 953 (001 ... 953) in 1 fingerprint per person mode. (2) 633 (001 ... 633) in 2 fingerprints per person mode. Power (V): 12V (ac / dc).
