Forum Thread: How to Make Wifi Rentals?

I am currently at my senior year and having research and I was thinking to make a Wifi rental booth software where I can enter their gadget name and give them a password of the wifi. every transaction has different passwords and it only applicable in the wifi once. In my country, most of the internet business here is a computer shop, which needed lots of desktops and such, more money needed to start this business. But my problem is I don't know how to make such a program, I don't have experience.
