Amakhadi e-NFC ahlukaniswe kakhulu abe ama-ID amakhadi namakhadi e-IC.Amakhadi omazisi ngokuyinhloko afundwa idatha ngamadivayisi okufunda e-NFC;Amakhadi e-IC anama-chips acubungula idatha yekhadi ngokukhethekile.
Ikhadi le-ID: rekhoda inombolo yekhadi kuphela, inombolo yekhadi ingafundwa ngaphandle komkhawulo futhi kulula ukulingiswa.Ikhadi likamazisi alikwazi ukubhala idatha, futhi okuqukethwe kwalo kwerekhodi (inombolo yekhadi) kungabhalwa kanye kuphela ngumkhiqizi we-chip, futhi umthuthukisi angakwazi ukufunda inombolo yekhadi ukuze ayisebenzise, futhi akakwazi ukwenza umthetho omusha wokuphatha inombolo ngokuvumelana nezidingo zangempela. .
Ikhadi le-IC: Ukufundwa nokubhala kwedatha erekhodiwe ku-ID kudinga ukuqinisekiswa kwephasiwedi okuhambisanayo, futhi ngisho nendawo ngayinye ekhadini inokuvikela okuhlukile kwephasiwedi ukuze kuvikelwe ngokugcwele ukuphepha kwedatha.Imvume yokufunda nokubhala ingasethwa ngephasiwedi ehlukene , okuyinto inikeza indlela enhle yokuphatha ye-hierarchical ukuqinisekisa ukuphepha kwesistimu.Ikhadi le-IC alikwazi ukufunda inani elikhulu ledatha ngabasebenzisi abagunyaziwe, kodwa futhi libhale inani elikhulu ledatha (njengenombolo yekhadi elisha, igunya lomsebenzisi, ulwazi lomsebenzisi, njll.) ngabasebenzisi abagunyaziwe.
Yiziphi izinhlobo ezahlukene zamakhadi e-IC?
Ikhadi le-M1: ikhadi elivamile le-IC, umkhakha 0 awukwazi ukuguqulwa, eminye imikhakha ingasulwa futhi ibhalwe kabusha ngokuphindaphindiwe;ngokuvamile amakhadi okulawula ukufinyelela kanye namakhadi ezikheshi esiwasebenzisayo amakhadi e-M1.Ikhadi le-M1 liyikhadi le-IC elakhiwe yi-NXP, igama eliphelele okuwuchungechunge lwe-NXP Mifare1.Okwamanje, ama-NFC chips asetshenziswa abakhiqizi abaningi bezingcingo eziphathwayo yi-NXP.
Ikhadi le-UID: ikhadi elijwayelekile lokukopisha, lingasula futhi libhale ngokuphindaphindiwe yonke imikhakha, isilawuli sokufinyelela asivumelekile uma kukhona i-firewall.
I-CUID: Thuthukisa ikhadi lokukopisha, elingasula futhi libhale yonke imikhakha ngokuphindaphindiwe, futhi lingangena ezindongeni eziningi zomlilo.
I-FUID: Ikhadi lekhophi elithuthukisiwe, umkhakha ongu-0 ungabhalwa kanye kuphela, futhi uba yikhadi le-M1 ngemva kokubhala.
I-UFUID: Ikhadi lekhophi elithuthuke kakhulu, umkhakha ongu-0 ungabhalwa kanye kuphela, ngemuva kokuthi ikhadi selivaliwe, kuzoba yikhadi le-M1, futhi uma ikhadi lingavalwanga, liba ikhadi le-UID.
Amakhadi e-IC alandela umqondo wamakhadi okuxhumana nama-chip okuqala, futhi okwamanje ahlukaniswe abe amakhadi e-IC othintana nawo namakhadi e-IC angaxhumene naye.Amakhadi e-IC angaxhunywanga ayingxenye yesigaba se-RFID, futhi okwamanje abhekisela kumakhadi e-IC anemvamisa ephezulu.Okuvame ukusetshenziswa kakhulu yikhadi le-M1 namakhadi alo ahambisanayo.
Umehluko phakathi kwamakhadi ochungechunge lwe-Mifare
1) Amakhadi ochungechunge lwe-Mifare ahlukaniswe abe Mifare UltraLight, eyaziwa nangokuthi i-MF0, ngokuya ngama-chips ahlukene asetshenziswa ekhadini;
2) I-Mifare S50 ne-S70, eyaziwa nangokuthi i-MF1;
I-Mifare Pro, eyaziwa nangokuthi i-MF2, i-Mifare Desfire, eyaziwa nangokuthi i-MF3.I-Mifare 1 inephasiwedi, i-Mifare UltraLight ayinayo iphasiwedi.I-M1/ML/UtralLight/Mifare Pro ihambisana nephrothokholi ye-14443A, i-AT88RF020 ithobela umthetho olandelwayo we-14443B
Umehluko phakathi kwe-Mifare S50 ne-Mifare S70:
1) Umfundi/umbhali uthumela imiyalo ehlukene yesicelo ekhadini;
2) Uhlobo lwekhadi (ATQA) amabhayithi abuyiswe impendulo ahlukile.Uhlobo lwekhadi (ATQA) le-Mifare S50 lithi 0004H, futhi uhlobo lwekhadi (ATQA) le-Mifare S70 lithi 0002H;
3) Umthamo kanye nesakhiwo senkumbulo kuhlukile, umthamo we-S50 ungamabhayithi angu-1K, kanti umthamo we-S70 ungamabhayithi angu-4K.
Njengamanje, amakhadi e-NFC asetshenziswa kakhulu ekuhlonzweni kokulawula ukufinyelela, amakhadi ebhasi, ukuhlonza ulwazi lomuntu siqu, ukulwa nokukhwabanisa, njll.
I-pda ephathwayo engenantambo ephathwayo ingasekela ukufunda nokubhala kwekhadi le-NFC,I-Shenzhen Handheld-wireless Technology Co., Ltd.inikeza ezihlukahlukeneUmbhali womfundi we-RFID, izibambiso ze-NFC,izikena zebhakhodi, izibambiso zebhayomethrikhi, amalebula e-elekthronikhi kanye nesofthiwe yesicelo eyenziwe ngezifiso, njll.
