Reader inside

Here there is some info on Reader hardware.

Disassemble the Reader (small Phillips screwdriver is needed)

  1. Unscrew 4 screws from the back side of the Reader. Unscrew 1 screw located in the cavity (at left) of the bottom silver panel
  2. Gently remove top and bottom silver plastic panels (some lateral movement may be needed)
  3. Unscrew 3 silver screw from the bottom side (normally hidden by plastic panel removed at the previous step)
  4. Remove 2 brackets from the top side (they are glued with soft glue and can be glued later again).
  5. Gently slide the PCB toward the top of the reader (Fig.1)
