The Canadian government is preparing to give merchants the ability to refuse to accept a particular NFC payment service if it attracts higher than usual fees — should that situation ever arise in the future, a document obtained by the WSJ reveals. “Should fees set by the payment card networks in respect of contactless payments made from a mobile device increase relative to card-based contactless payments, payment card networks will develop the technical specifications to ensure that merchant acceptance of contactless payments made from a mobile device can be cancelled at the point-of-sale without disabling other forms of contactless payments acceptance,” the document states.
