Question about Brother HL-1210W

Excuse me, why doesn't it have an NFC print sticker? it doesn't have any sticker on it ! like the samsung laser has instead. on the app with wi fi and blutut it doesn't go! it keeps searching but doesn't find! i wanted to do it with nfc! but there is no nfc sticker! do you have to buy it separately?!? thank you x answer!!!
