1. A biometric sensor module for detecting a biometric feature of a user, the biometric sensor module comprising:
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;
a bottom flexible film attached to a back side, opposite the front side, of the biometric sensor, the bottom flexible film carrying at least one electrically conductive line electrically connectable to the biometric sensor and electrically connectable to an external electrical circuit,
a top film attached to the biometric sensor closer to the front side of the biometric sensor than the bottom flexible film,
wherein the bottom flexible film includes a bent portion such that the bottom flexible film is bent towards the top film, and
wherein the biometric sensor is attached to a first side of the bottom flexible film, the bottom flexible film further carrying at least one electrically conductive pad on a second side opposite the first side, the at least one electrically conductive pad being electrically connected with at least one electrically conductive line.
