How reliable is palm scanning compared to fingerprint?

The palm scanner is less sensitive to contamination and skin damage, which makes it preferable for industrial environments and medicine.

Is special staff training required to operate the terminal?

No, the access procedure is intuitive: you just need to present your hand or look into the camera; registering new users takes minutes.

Can SpeedFace M4 be integrated into an existing ACS via Wiegand?

Yes, the Wiegand interface provides direct connection to most access system controllers without replacing existing equipment.
