Amakhadi e-NFC ahlulwe kakhulu abe ngamakhadi esazisi kunye namakhadi e-IC.Amakhadi esazisi afundwa ikakhulu zizixhobo zokufunda ze-NFC;Amakhadi e-IC aneetshiphusi eziqhuba ngokuthe ngqo idatha yekhadi.
Ikhadi le-ID: bhala kuphela inombolo yekhadi, inombolo yekhadi inokufundwa ngaphandle komda kwaye kulula ukuxelisa.Ikhadi le-ID alikwazi ukubhala idatha, kunye nomxholo werekhodi (inombolo yekhadi) ingabhalwa kanye kuphela ngumenzi we-chip, kwaye umphuhlisi unokufunda kuphela inombolo yekhadi ukuze asetyenziswe, kwaye akakwazi ukwenza umgaqo wolawulo lwenombolo entsha ngokweemfuno zokwenene. .
Ikhadi le-IC: Ukufundwa nokubhala kwedatha erekhodiweyo kwi-ID ifuna ukuqinisekiswa kwephasiwedi ehambelanayo, kwaye indawo nganye ekhadini inokhuseleko oluhlukeneyo lwephasiwedi ukukhusela ngokupheleleyo ukhuseleko lwedatha.Imvume yokufumana kunye nokubhala inokusekwa kunye nephasiwedi eyahlukileyo , leyo ibonelela ngendlela efanelekileyo yolawulo lwenqanaba lokuqinisekisa ukhuseleko lwenkqubo.Ikhadi le-IC alikwazi ukufunda kuphela inani elikhulu ledatha ngabasebenzisi abagunyazisiweyo, kodwa libhala inani elikhulu ledatha (njengenombolo yekhadi elitsha, igunya lomsebenzisi, ulwazi lomsebenzisi, njl.) ngabasebenzisi abagunyazisiweyo.
Zeziphi iintlobo ezahlukeneyo zamakhadi e-IC?
Ikhadi le-M1: ikhadi le-IC eliqhelekileyo, icandelo 0 alikwazi ukuguqulwa, amanye amacandelo anokucinywa kwaye abhalwe ngokuphindaphindiweyo;ngokuqhelekileyo amakhadi okulawula ukufikelela kunye namakhadi e-elevator esiwasebenzisayo ngamakhadi e-M1.Ikhadi le-M1 likhadi le-IC eliphuhliswe yi-NXP, igama elipheleleyo eliyi-NXP Mifare1 series.Okwangoku, iitshiphusi ze-NFC ezisetyenziswa ngabenzi beefowuni eziphathwayo yi-NXP.
Ikhadi le-UID: ikhadi lekopi eliqhelekileyo, linokucima ngokuphindaphindiweyo kwaye libhale onke amacandelo, ulawulo lokufikelela aluvumelekanga ukuba kukho i-firewall.
I-CUID: Phucula ikhadi lekopi, elinokucima kwaye libhale onke amacandelo ngokuphindaphindiweyo, kwaye lingangena kwiifirewall ezininzi.
I-FUID: Ikhadi lekopi eliphuculweyo, icandelo le-0 lingabhalwa kanye kuphela, kwaye liba yikhadi le-M1 emva kokubhala.
I-UFUID: Ikhadi lekopi eliphambili, icandelo le-0 lingabhalwa kanye kuphela, emva kokuba ikhadi litywinwe, liya kuba likhadi le-M1, kwaye ukuba ikhadi alitywinwanga, liba ikhadi le-UID.
Amakhadi e-IC alandela ingqikelelo yamakhadi oqhagamshelwano lwetshiphu yokuqala, kwaye okwangoku ahlulwe abe ngamakhadi e-IC oqhagamshelwano kunye namakhadi e-IC angaqhagamshelwanga.Amakhadi e-IC angaqhagamshelwanga ngawodidi lwe-RFID, kwaye ngoku abhekiselele kumakhadi e-IC asebenza kakhulu.Eyona isetyenziswa ngokuqhelekileyo likhadi leM1 kunye namakhadi ahambelanayo.
Umahluko phakathi kwamakhadi eMifare series
I-1) Amakhadi e-Mifare series ahlula kwi-Mifare UltraLight, eyaziwa ngokuba yi-MF0, ngokweetshiphu ezahlukeneyo ezisetyenziswe kwikhadi;
2) I-Mifare S50 kunye ne-S70, eyaziwa ngokuba yi-MF1;
I-Mifare Pro, eyaziwa ngokuba yiMF2, iMifare Desfire, eyaziwa ngokuba yiMF3.I-Mifare 1 inegama lokugqitha, iMifare UltraLight ayinalo igama eliyimfihlo.I-M1/ML/UtralLight/Mifare Pro ithobela iprotocol ye-14443A, AT88RF020 ithobela iprotocol ye-14443B
Umahluko phakathi kweMifare S50 kunye neMifare S70:
1) Umfundi/umbhali uthumela imiyalelo eyahlukeneyo yesicelo kwikhadi;
2) Uhlobo lwekhadi (ATQA) bytes ezibuyiswe yimpendulo zahlukile.Uhlobo lwekhadi (ATQA) le-Mifare S50 yi-0004H, kunye nohlobo lwekhadi (ATQA) le-Mifare S70 yi-0002H;
3) Umthamo kunye nokwakhiwa kwememori kuyahluka, umthamo we-S50 yi-bytes ye-1K, kunye nomthamo we-S70 yi-4K bytes.
Okwangoku, amakhadi e-NFC asetyenziswa kakhulu ekuchongeni ulawulo lofikelelo, amakhadi ebhasi, ukuchongwa kolwazi lomntu siqu, ukuchasana nenkohliso, njl.
I-pda ephathwayo engenacingo ephathwayo inokuxhasa ukufunda nokubhala kwekhadi le-NFC,I-Shenzhen Handheld-wireless Technology Co., Ltd.inikeza ezahlukeneyoUmbhali womfundi weRFID, NFC eziphathwayo,izikena zebhakhowudi, ii-handheld zebhayometriki, iilebhile ze-elektroniki kunye nesoftware eyenziwe ngokwezifiso, njl.
