I have a feeling the MCX participants and card issuers are going to come to an impasse over their respective agreements. All the issuers have to do is require that terminals capable of NFC (for the purpose of accepting PayPass/PayWave) not have the functionality disabled. This will put the merchants in a bind and force them either to replace the terminals altogether, or re-enable NFC.
Which is stupid. Apple Pay is the most available way to pay for something that is as secure as chip & pin in the USA.
