Abstract

Provided is a biometric information imaging module, used for imaging palm veins, and method of using same. The imaging module includes a housing with a cover attached to a top of the housing; a lens assembly with a lens for taking images provided in the housing; a light shielding structure provided around at least part of the lens of the lens assembly for shielding the lens from light reflected from the cover; and an image sensor to convert light focused by the lens assembly to photoelectric conversion to an electrical signal. The lens assembly is attached to a first circuit board and the light shielding structure is connected to a second circuit board in the housing.
