For context, MST or magnetic secure transmission, allows a phone to transmit an EM signal that emulates the physical action of swiping a magstripe based card. As in, it works with all the legacy "card swipe" terminals. Samsung phones up to like the S20(?) supported this, allowing them to technically work basically everywhere with no integration needed.
