a single-piece frame comprising a front side and a back side and a having a footprint matching the [ a ] footprint of the magnetic reader head compartment [ , wherein the frame comprises top and bottom frontward extending plates, ] and wherein the front side [ of the frame ] attaches to a back wall of the magnetic reader head compartment [ when the magnetic reader head compartment is inserted in an opening in the front side of the frame between the top and bottom frontward extending plates ] while allowing the magnetic reader head compartment to move out or retract from the frame [ when displaced by a card] ; and
an elastic component to be placed at the back side of the frame and to push the frame out [ toward the card ] in order to press the magnetic reader head compartment against a magnetic card stripe [ of the card] ,
wherein said elastic component comprises a metal plate spring,
wherein the metal plate spring comprises a curved elastic thin complete rectangular body having a central through-opening and left and right side tabs, the left and right side tabs loosely coupling the elastic component within the frame, and
wherein the metal plate spring includes a first end and a second end, the first end and the second end able to extend beyond a top end and a bottom end, respectively, of the single-piece frame when the metal plate spring flattens in response to pressure applied to the magnetic reader head compartment.
