    The internal EEPROM can handle 255 cards (256 with the master card), but if you need more than that, sure... anything is possible! About scheduling, it would be best to use a different lock than the electric strike mechanism, if you mean something like unlocking on business hours.

    Done! I've added the schematics to the project.

    Indeed, for this kind of project you need some battery backup.
    I bought a really nice power source that has a battery built-in, like a small UPS.
    It has 800mA, by my calculations it's going to hold for about 16h.
    In the case of complete power failure, the door will stay locked and you can use your key as you normally do.
    That's why I went with the electric strike over the electromagnetic lock.
