EMV rules seems to have been the PIN straw that broke the POS camel's back, as even Apple Pay has suffered performance degradations following EMV migrations. The big picture arguments about security-that it's blindingly obvious that PIN is far more secure than signature-are obscured by the reality that this is really a fight about interchange fees. And the EMV argument that the path to PIN must be glacially slow or else American consumers will freak out from the change, despite the fact that most are quite used to PINs from ATMs and debit cards, is frighteningly valid. And here it is in the land of EMV rules that grocery giant Kroger makes it stand.
