you may have gotten a temporary one. i got some, too, in the mail. this is what those chips look like. the new cards will be nearly identical to your magnetic strip cards. but these are hutch hard toer t hack and to duplicate. the deadline is tomorrow for all u.s. retailers to upgrade their systems to accept these new cards. so rather than swiping your card, you re now going to be dipping your card into these terminals. it s very similar in canada, europe, they ve had this for years. not everyone is ready yet. 60% of americans still have their old cards. and so far, there are more than 1.2 billion cards that need to be swapped out. and nearly one in four businesses haven t yet upgraded their credit card terminals. so big issue for that is money. as far as what that means for consumers, the deadline is tomorrow. they will not have a penalty if you don t have your card yet
