 ==== Version 2 ====
-In progress.
+The goal of this version is to make the assembly process easier and more reliable.
+It consists of a laser-cut acrylic plate that fits over a standard 1-gang UK electrical box. A PCB is glued to the inside of the plate, and this PCB integrates the PN532 module, buzzer, LED and wiring connections.
