Help Galaxy S7 Icon Question

[YoungGun1078]

Hey guys, new to the forum. If this questions has been asked, I couldn't find it so apologies.
Anyway, long time iPhone user just switched to Android and loving it, but I've got an icon on the very top of my screen that I can't figure out. Obviously, the one in the little red box. Any answers would be great. Thanks!

Thats the NFC (Near Field Communication). That allows you to use NFC tags to toggle certain phone settings. You can toggle that with the extended shortcut toggles. Pull down the notification shade using two fingers, or press the arrow on the upper right when you lower the shade.
