Last time I checked, you've got to swipe a magnetic-stripe card (we mainly use C&P/contactless). Unless there's some really cool sci-fi pop-up plastic tab inside the phone / case / a separate re-programmable card, I'm really curious as to how this could work?
- e_y_ 3y agoI haven't been able to find a detailed explanation of how it works. Somehow it emits a magnetic pulse that simulates the card being swiped, without having to physically swipe the card. Best guess is that it uses some kind of magnetic induction to induce a current in the reader the same way that a swipe would. I never had a Samsung phone so I can't comment on how it worked in practice or the reliability. Can't find any mention of having to hold your phone a particular way so presumably it's direction-independent, although apparently sometimes it might not be possible to hold your phone close enough for the reader to pick it up. https://en.wikipedia.org/wiki/Magnetic_secure_transmission https://en.wikipedia.org/wiki/Magnetic_secure_transmission
