Hello,
I'm working on a skill crane. Some prizes that are dispensed will have a key attached to them. When a customer wins a prize that has a key I need to trip a relay that will turn on a bell and some lights. I'm wondering what I could use to attach to the key that would signify a winner? I would like to use a RFID system but don't have too much experience in those. Just wondering if anyone has some ideas that wont break the bank. The prize chute is about 6" square. Thanks in advance ! John Ross
