Makhadi a NFC amagawidwa makamaka kukhala ma ID ndi IC.Ma ID makadi amawerengedwa makamaka ndi zida zowerengera za NFC;Makhadi a IC ali ndi tchipisi tomwe timasunga deta yamakhadi.

Khadi la ID: ingolembani nambala yamakhadi, nambala yamakhadi imatha kuwerengedwa popanda malire ndipo ndiyosavuta kutsanzira.Khadi la ID silingalembe deta, ndipo zolemba zake (nambala yamakhadi) zitha kulembedwa kamodzi kokha ndi wopanga chip, ndipo wopangayo amatha kuwerenga nambala yamakhadi kuti agwiritse ntchito, ndipo sangathe kupanga lamulo latsopano loyang'anira manambala malinga ndi zosowa zenizeni. .

Khadi la IC: Kuwerenga ndi kulemba kwa deta yolembedwa mu ID kumafuna kutsimikizika kwachinsinsi chofananira, ndipo ngakhale dera lililonse mu khadi liri ndi chitetezo chosiyana chachinsinsi kuti chitetezere chitetezo chokwanira.Chilolezo chowerengera ndi kulemba chikhoza kukhazikitsidwa ndi mawu achinsinsi osiyana , omwe amapereka njira yabwino yoyendetsera kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka chitetezo.Khadi la IC silingawerenge kuchuluka kwa deta ndi ogwiritsa ntchito ovomerezeka, komanso kulemba zambiri zambiri (monga nambala yatsopano ya khadi, ulamuliro wa ogwiritsa ntchito, chidziwitso cha ogwiritsa ntchito, etc.) ndi ogwiritsa ntchito ovomerezeka.

Kodi mitundu yosiyanasiyana ya makadi a IC ndi iti?
Khadi la M1: Khadi la IC wamba, gawo 0 silingasinthidwe, magawo ena amatha kufafanizidwa ndikulembedwanso mobwerezabwereza;nthawi zambiri makhadi owongolera mwayi wolowera ndi makadi okwera omwe timagwiritsa ntchito ndi M1.Khadi la M1 ndi khadi la IC lopangidwa ndi NXP, dzina lonse lomwe ndi mndandanda wa NXP Mifare1.Pakadali pano, tchipisi ta NFC zomwe zimagwiritsidwa ntchito ndi opanga mafoni ambiri ndi NXP.
Khadi la UID: Khadi lachikopa wamba, limatha kufufuta ndikulemba magawo onse mobwerezabwereza, kuwongolera kolowera ndikosavomerezeka ngati pali chowotcha moto.
CUID: Kwezani khadi lokopa, lomwe limatha kufufuta ndikulemba magawo onse mobwerezabwereza, ndipo limatha kulowa paziwopsezo zambiri.
FUID: Khadi lamakope apamwamba, gawo la 0 likhoza kulembedwa kamodzi kokha, ndipo limakhala khadi la M1 mutalemba.
UFUID: Khadi lapamwamba kwambiri, gawo la 0 likhoza kulembedwa kamodzi kokha, khadi litasindikizidwa, lidzakhala M1 khadi, ndipo ngati khadi silinasindikizidwa, limakhala khadi la UID.

Makhadi a IC amatsatira lingaliro la makhadi olumikizana ndi chip oyambirira, ndipo pakadali pano agawidwa kukhala makhadi a IC ndi makadi a IC osalumikizana nawo.Makhadi a IC osalumikizana nawo ali m'gulu la RFID, ndipo pakadali pano amatanthauza makhadi a IC othamanga kwambiri.Chogwiritsidwa ntchito kwambiri ndi M1 khadi ndi makhadi ogwirizana nawo.

Kusiyana pakati pa makhadi a Mifare
1) Makhadi angapo a Mifare amagawidwa kukhala Mifare UltraLight, yomwe imadziwikanso kuti MF0, malinga ndi tchipisi tosiyanasiyana tomwe timagwiritsidwa ntchito pakhadi;
2) Mifare S50 ndi S70, yomwe imadziwikanso kuti MF1;
Mifare Pro, yomwe imadziwikanso kuti MF2, Mifare Desfire, yomwe imadziwikanso kuti MF3.Mifare 1 ili ndi mawu achinsinsi, Mifare UltraLight ilibe mawu achinsinsi.M1/ML/UtralLight/Mifare Pro itsatira protocol ya 14443A, AT88RF020 itsatira 14443B protocol

Kusiyana pakati pa Mifare S50 ndi Mifare S70:
1) Wowerenga / wolemba amatumiza malamulo osiyanasiyana opempha ku khadi;
2) Mtundu wa khadi (ATQA) mabayiti obwezeredwa ndi yankho ndi osiyana.Mtundu wa khadi (ATQA) wa Mifare S50 ndi 0004H, ndipo mtundu wa khadi (ATQA) wa Mifare S70 ndi 0002H;
3) Mphamvu ndi kapangidwe ka kukumbukira ndizosiyana, mphamvu ya S50 ndi ma byte 1K, ndipo mphamvu ya S70 ndi ma byte 4K.

Pakadali pano, makhadi a NFC amagwiritsidwa ntchito kwambiri pozindikiritsa zowongolera, makhadi a basi, chidziwitso chaumwini, zotsutsana ndi zabodza, ndi zina zambiri.
Pda ya m'manja yopanda zingwe imathandizira kuwerenga ndi kulemba kwa NFC,Malingaliro a kampani Shenzhen Handheld-wireless Technology Co., Ltd.amapereka zosiyanasiyanaWolemba RFID wowerenga, NFC zogwirizira m'manja,barcode scanner, zonyamula m'manja za biometric, zolemba zamagetsi ndi mapulogalamu osinthidwa makonda, etc.
