I have 3 pads I want to rent out internet time on them. I want customers to be able press a surf the net button on the Android tablet. I want an end surfing button which ends session after a code is put in and calculates the charge.I want the net only to be surfed and maybe a number of free games. After that I want the pad locked down and pass word protected. The program must keep a log of time the pad is surfed for and must send this info to me. It must be able to deal with being turned off by users so that it does not reset the machine and we must have a way to restore the machine easily.
Ready to start. I did something similiar to this when I worked in the Navy on laptops to service members so that they wouldn't spend more than a certain amount of time online and allow others to be able to use the laptops for the same amount of time.
