Multimode door access control readers provide multiple ways of controlling entry. This can include RFID readers and pin numbers, or multiple biometrics. Security can be increased by using multiple modes together. In other words a person can place their fingerprint on the readers as well as using their RFID credential. This adds additional security. Alternatively if you don’t need the enhanced security, you can use one of the modes instead of another. For example, if a person’s fingerprint doesn’t work, they can use their credential instead.
