Build your own coin-operated Wi-Fi hotspot ticketing system

Reddit user “jeff122885” has come up with a fairly simple yet clever coin-operated ticketing system for his Wi-Fi network. The setup consists of a Ch-926 multi-coin acceptor, a MikroTik Groove, and an Arduino Uno with a microSD card module. The unique password for the hotspot is stored in the SD card and read by the Arduino. Once the coins are deposited, the voucher code, Wi-Fi name, duration, cost, and instructions on how to connect are printed onto a receipt. You can see it all in action below!
