Are you sure? Only Samsung (and LG apparently?) have the hardware feature where it tricks a magnetic stripe reader into thinking a card was swiped. However, the kind of magstripe emulation I meant is a feature of EMV where it can provide the same information as a magnetic stripe would, but over NFC, for compatibility with legacy (US) payment systems. Does Apple not support this latter system either? (It's apparently not supported for Apple Card, but Google isn't helping me for Apple Pay.)
