PCI would be interested in Apple Pay and Android Pay as both use EMV over NFC, which provides much the same level of security as the Chip: both use nonces, so even if the data gets stolen, it's of no use to credit card thieves, plus both require explicit user consent to unlock the feature (thus why you can't use them without actual lockscreens), preventing even an NFC skimmer posing as a merchant from going unnoticed.
