He mea hanga te tohu ā-whakarewa NFC ki te pepa piri, ki te kāri PVC rānei, he paparanga rauemi mimiti, ka taea ai te whakatutuki i te pānga o te ārai-whakararuraru konganuku. Ka taea te pānui me te tuhi i te tapanga ki runga i te mata o te konganuku. Ka taea e te PVC me te tapanga ātete-konganuku te ārai i te wai, te waikawa, te kawakore me te tukinga, ā, ka taea te whakamahi ki waho.
Ka taea te whakamahi i te tohu NFC anti-konganuku i hangaia e MINA me ngā kāwai e whā o ngā tapanga NFC e whai ake nei:

Ko te momo tuatahi o te tohu ārai-whakarewa NFC e ahu mai ana i te kawa 14443a. Ko te mahara tapanga iti rawa he 96 paita, ka taea te whakawhānui ake. Mena he ngawari noa te rokiroki pānui-tuhi o ngā tohu, pēnei i te whakatinanatanga o te mahi pānui atamai ngawari, ka tino wātea aua tohu. Ko te nuinga o te wā ka whakamahia tēnei momo tohu hei pānui i ngā mōhiohio, ā, he ngawari te whakahaere me te iti o te utu.

Ko te momo tuarua o te tapanga ārai-whakarewa NFC e hangai ana hoki ki te kawa 14443a, engari ko te kāri anake i whakaratohia e Phlips ka tautokona.

Ko te momo tuatoru o te tapanga ātete whakarewa NFC ko te momo hangarau fecila i whakaratohia motuhaketia e Sony.

Ko te momo tuawhā o te tohu NFC anti-konganuku he kawa 14443A/B. Nō te tohu atamai tēnei momo tohu, ka whiwhi i ngā tohutohu a te wae raraunga kawa tono (APDU), he nui te wāhi rokiroki, ka taea te whakaoti i ētahi momo whakamotuhēhēnga, haumarutanga rānei, ā, ka taea te whakamahi hei whakatutuki i te taunekeneke atamai me te mahi e pā ana ki te tapanga atanga rua. He whānuitia ngā tono o tēnei momo tohu, ā, ka taea te urutau ki te rangahau me te whanaketanga tonu ā muri ake nei.
