Biometric sensor module for card integration

A biometric sensor module for detecting a biometric feature of a user comprises: a biometric sensor comprising an array of sensing elements for acquiring sensing signals indicative of a biometric feature of a user, the array of sensing elements arranged facing towards a front side of the biometric sensor. Further, the biometric sensor module comprises a bottom flexible film attached to a back side, opposite the front side, of the biometric sensor. The bottom flexible film can carry at least one electrically conductive line electrically connectable to the biometric sensor and electrically connectable to an external electrical circuit. The biometric sensor module further comprises a top film attached to the biometric sensor closer to the front side of the biometric sensor than the bottom flexible film. The flexible film includes a bent portion such that the flexible film is bent towards the top film.
