its not always the store , but the pos , ingenico dosent , moneris dosent usually , its mainly verifone ones that do in cnada anyways , bestbuy checks future shop does lowes , but they can always compare the card to the recipt if you look sketchy
bewar of some POS wich ask for zip code ) i had see this in usa when i there , another mention of discover may do this as wel as aMEX may request cvv / ccid
it suck if your dump good but cvv wont match lol! ))
