An enclosure (100) for a biometric sensor (102) is described. The enclosure (100) comprises a cabinet (104) having a plurality of surfaces (106). The biometric sensor (102) placed inside the cabinet (104) on a holder (108) fixed on a primary surface (106-1) from amongst the plurality of the surfaces (106). A secondary surface (106-2) from amongst the plurality of surfaces (106) is opposite to the primary surface (106-1). The secondary surface (106-2) is substantially transparent to electromagnetic rays emitted by the biometric sensor (102).
