The PCI Council is allowing the most sensitive part of a payment card transaction to happen on a device that it acknowledges is highly dangerous and unstable.

“This will open up MPOS worldwide in a way we’ve never seen. It’s absolutely groundbreaking for micromerchants” who process “less than [the equivalent of] $50,000 U.S. a year,” said Todd Ablowitz, CEO of the Double Diamond Group.

Ablowitz argued that the costs and fees involved in payments make adding a PIN pad — along with its PCI certification — unacceptable for many non-U.S. micromerchants, which have always struggled with chip and PIN. “In a place where PIN is mandatory, micromerchants have been left out,” he said.
