I-MIFARE DESFire EV2 2K 4K 8K Blank RFID Card

 
Ikhadi le-MIFARE DESFire EV2 2K 4K 8K RFID limele isiqongo sobuchwepheshe bekhadi le-smart ngaphandle kokuthinta.
Inikeza ukuvikeleka okuphakeme nokuguquguquka, le mikhiqizo ye-NXP MIFARE iletha ukuvikeleka kwezinga lebhizinisi okunamandla okuhlanganisa okungenamthungo okulawula ukufinyelela kwesimanje kanye nezinhlelo zokusebenza zedolobha ezihlakaniphile. Kulesi sihloko, sizocubungula izici, izinzuzo,
kanye nokucaciswa kobuchwepheshe kwe-MIFARE DESFire EV2, ehlinzeka ngomhlahlandlela ophelele wabasebenzisi abangaba abasebenzisi.

 

Uhlolojikelele Lomkhiqizo Nezinzuzo

I-MIFARE DESFire EV2 isebenza ngefrikhwensi engu-13.56MHz futhi yakhelwe ukuhlangabezana nezindinganiso eziphakeme kakhulu zokuphepha.
Itholakala ngezinhlobo ezintathu zememori: 2K, 4K, kanye namabhayithi angu-8K, ihlinzekela ngezidingo ezahlukene zesitoreji.
Ukubethela okuthuthukile kwekhadi nezici zokuphepha eziqinile zilenza lilungele izinhlelo zokusebenza ezidinga ukuvikelwa kwedatha okusezingeni eliphezulu.

 

Izinzuzo Eziyinhloko

 

  1. Ukuvikeleka Okuthuthukisiwe: Ngezindlela zokubethela ezithuthukisiwe ezifana ne-DES, 2K3DES, 3K3DES, ne-AES, i-MIFARE DESFire EV2 iqinisekisa ukudluliswa kwedatha okuvikelekile nokugcinwa.
  2. I-Versatility: Ifanele uhla olubanzi lwezinhlelo zokusebenza, okuhlanganisa ukulawula ukufinyelela, izithuthi zomphakathi, i-e-payment, nezinhlelo zokwethembeka.
  3. Ukuhlanganiswa Okungenamthungo: Ithobelana ngokugcwele namazinga e-ISO14443-A kanye ne-NFC Type 4, iqinisekisa ukuhambisana nengqalasizinda yokufunda ye-NFC ekhona.
  4. Ukusebenza Okuphezulu: Amazinga okudlulisa idatha asheshayo kanye nomthamo wememori ephezulu ayenza ilungele izindawo ezifunayo.

 

Uhlaka Lomkhiqizo

 

1. Izici Zokuvikela Ezithuthukile

 

Ukuvikeleka kubaluleke kakhulu ekwakhiweni kwe-MIFARE DESFire EV2.
Ikhadi lihlanganisa izinjini ze-cryptographic ezisekelwe ku-hardware, ukuqinisekiswa kwe-mutual three-pass,
kanye nemithethonqubo yokudlulisa idatha evikelekile. Iphinde ibe nesitifiketi sokuphepha esijwayelekile se-EAL5+,
ukuqinisekisa izinga eliphezulu lokuvikela ekuhlaselweni okuyinkimbinkimbi.

 

2. Izinketho Zenkumbulo: 2K, 4K, kanye no-8K

 

I-MIFARE DESFire EV2 itholakala ngezinhlobo ezintathu zememori: 2K, 4K, kanye namabhayithi angu-8K. Lokhu kuvumelana nezimo kuvumela abasebenzisi ukuthi bakhethe umthamo ofanelekile wesitoreji ngezidingo zabo ezithile, noma ngabe okokulawula ukufinyelela okulula noma amasistimu ezicelo eziningi ayinkimbinkimbi.

 

3. Ukuhambisana ne-ISO14443-A kanye Nohlobo 4 lwe-NFC

Ikhadi lithobelana ngokugcwele namazinga e-ISO14443-A kanye ne-NFC Type 4, okulenza lihambisane nebanga elibanzi labafundi be-NFC nengqalasizinda ekhona. Lokhu kuqinisekisa ukuhlanganiswa okungenamthungo nokusebenzisana nezinhlelo zamanje.

 

4. Izilinganiso Zokudluliswa Kwedatha Ezisheshayo

I-MIFARE DESFire EV2 isekela amazinga okudlulisa idatha afika ku-848 kbps, iqinisekisa ukuxhumana okusheshayo nokuphumelelayo phakathi kwekhadi nomfundi. Lokhu kubalulekile ezinhlelweni ezidinga ukucutshungulwa kwedatha ngokushesha kanye nokusebenza okuphezulu.

 

5. Idizayini Eqinile Nehlala isikhathi eside

Ikhadi lakhelwe ukumelana nezindawo ezinokhahlo kanye nokusetshenziswa njalo. Inikeza isikhathi sokugcinwa kwedatha seminyaka engu-25 kanye nokubekezela kokubhala kwemijikelezo engu-500,000, okuyenza ibe ukukhetha okuthembekile kwezinhlelo zokusebenza zesikhathi eside.

 

6. Ukusekelwa Kwezicelo Eziningi

I-MIFARE DESFire EV2 isekela izinhlelo zokusebenza eziningi ekhadini elilodwa, ngenxa yesakhiwo sayo sefayela esivumelana nezimo namandla okuphatha isicelo. Lokhu kuyenza ilungele izinsiza zedolobha elihlakaniphile, lapho ikhadi elilodwa lingasetshenziswa ukuthutha umphakathi, ukulawula ukufinyelela, i-e-payment, nokunye.
