I actually hope they're not backwards compatible. That'll be similar to having to wait behind someone at Wal-Mart with a check these days. Really? It's being processed immediately and electronically, just like a debit card. Get a debit card.I don't think they have a choice really except to release it immediately.
One of two things will happen. Either the mandated EMV readers will still have a swipeable slot in them to accommodate the lengthy change over away from the magnetic strips...or they will eliminate them completely and force a mass adoption to EMV immediately.
I believe if the swipe slots disappear that Samsung has very little time to take advantage of their magnetic "NFC" feature. If the new EMV readers are backwards compatible then Samsung would have more breathing room.
Instead of that, it'll be, Really? I have to wait for you to swipe your old card. Get a new card. Haha!
