Purchased this in advance with high hopes, in the meantime the chip came out and every time I go to use the coin the machine asks me to insert card and I can't because the coin doesn't have the chip that is unique to each of my credit cards: ( I contacted support and demanded a refund for a piece of crap that only works at 1 of the store I frequent because they have not upgraded their credit card scanner yet and they say too bad, we already put your name on it! HUH? You sold me a piece of crap that doesn't work as intended... bad MODEL!
