Can ievo Fingerprint Readers be Used Without the Interface Board?

Can the ievo fingerprint reader heads be used without the Interface Board?

No. 

The Interface Board provides the brains and the power for the reader head. The Interface Board should be installed on the secure side of the door, in order to keep the fingerprint template data contained on it secure. 

The reader head cannot be used on its own without an Interface Board. 

Each Interface Board can run up to two ievo fingerprint reader heads.
