Nfc sbeam

So im a little confused i used to own a sprint gs3 and i could use sbeam no prob i recently got the i9300 i was rooted but flashed it back to stock 4.1.2 via odin and i tried to sbeam my friend and nothing happened both of us had all the settings turned on but she is running an older version i beleive 4.0.4 could that be the prob or the stock rom i used the issue?
