Room77: Light on Numbers & Physical Security

[rootzoll]

When staff in the Room77 was punching in the amounts they almost always had a hard time seeing the numbers in the keypad of the m5stack faces kit ... so it would be cool to have a solution to better see the numnbers in a dark environment.

Also the device could need a bit of physical protection ... maybe some stickers covering the ports to make it it a bit harder to quickly temper with the device.

Been meaning to sort this, I know M5Stack have a sticker template somewhere we could use.
