coin and keyless locker machines needed

i need a locker that its compartments will be used by costumers for a short period of time. renting compartments for short term and paying (the machine) with coinsthe locker (or each compartment) will have a mechanism of coin recieving. so people can pay for the using the lockerafter they have paid, it is critical that they will have a keypad to choose the code for their copartment ( i repeat - it has to be keyless) and maybe even a small screen for more convienience so basically we are talking about an indipendent machine that doesnt need manager assistance at all. it is communicating with the costumer from the second he chose to rent a compartment until the minute his money expired and he picked his stuff and left.1 paying with coins2 choosing a code3 reopening the locker as much as wanted untill time's up
