Hey,
I need to setup a hot spot where i can sell prepaid data vouchers, but userman only allows u to govern it by time. I want to use size.
So i want to be able to generate like 100 500MB vouchers that i can then give to random shops and caffies and they can then sell them to people like u buy pre paid air time.
Then they just use that username and password till its finished and they can then buy annother one?
How can i change it to size and not time?
