It can dispense 10 coins maximum per transaction and the least amount that it can dispense is Php1 coin. The largest denomination that the machine can accept is Php100 bill and the least it can accept is Php 1 coin.The group conducted experiments to test the accuracy of the amount inserted equivalent to the number of coins to be dispensed.
