Kuzo zonke izizukulwane, i-NXP iqhubeke njalo ithuthukisela ulayini we-MIFARE DESFire wama-IC, icwengisa izici zawo ngokusekelwe kumathrendi e-tech anoveli kanye nezidingo zabasebenzisi. Ngokuphawulekayo, i-MIFARE DESFire EV1 ne-EV2 bathole ukuthandwa okukhulu ngezinhlelo zabo zokusebenza ezihlukahlukene nokusebenza okuhle. Noma kunjalo, ukwethulwa kwe-DESFire EV2 kubone ukuthuthukiswa kwamakhono nezici ngaphezu kweyandulelayo - EV1. Lesi sihloko sikhanyisa ukukhiqizwa, izinto zokwakha, nezinye izici ezibalulekile zalawa makhadi.
I-MIFARE DESFire Cards Production
Ukukhiqizwa kweMIFARE DESFire amakhadiihlanganisa ubuchwepheshe obusha kanye nezilawuli zekhwalithi eziqinile ukuze zenze imikhiqizo emelene novivinyo lwesikhathi nokuhluka kohlelo lokusebenza. Lawa makhadi awumphumela wenqubo yokukhiqiza eqinile ethobela izindinganiso zomhlaba wonke zokukhiqizwa kwe-IC. Isigaba ngasinye sokukhiqiza-kusuka ekwakhiweni kuya ekuthumeni-sihlangabezana nokucaciswa okuphezulu kakhulu, ukuqinisekisa ukuthi lawa makhadi anikeza isisombululo esinokwethenjelwa nesisebenzayo ezimweni ezihlukahlukene zokusetshenziswa.
Izinto ezihlukile ze-MIFARE DESFire Cards
Amakhadi e-MIFARE DESFire ahlanganisa ikakhulukazi ipulasitiki—imvamisa i-PVC—enzelwe ukuqina, ukuguquguquka, kanye nokusetshenziswa kwesikhathi eside. Nokho, ngokusekelwe kuzinhlelo zokusebenza ezithile nezimfuneko zekhasimende, lawa makhadi angase futhi ahlanganise i-PVC, i-PET, noma i-ABS. Lokhu okuhlukile ngakunye kubamba izici zayo ezibonakalayo ezihlukile futhi ngakho-ke kufaneleka kumongo othile. Okubalulekile, zonke izinto zekhadi le-DESFire zikhethwa ngokucophelela, ziqinisekisa ikhwalithi nokuvumelana.
Inzuzo yamakhadi e-MIFARE DESFire
MIFARE DESFire amakhadiyethula izinzuzo eziningi ezifaka ukuvikeleka okuphakeme, ukuphatha idatha ngendlela efanele, nokusetshenziswa okubanzi. Izici zabo ezithuthukisiwe ze-cryptographic ezifana nokubethela kwe-AES-128 zenza ukuthengiselana kwedatha kuvikeleke, kuyilapho amandla okuphatha izinhlelo zokusebenza eziningi kuthuthukisa ukuguquguquka kwazo. Ibanga lokusebenza elithuthukisiwe, izici zenoveli ezifana ne-Rolling Keysets kanye ne-Proximity Identification, nokuhambisana okusemuva kuphakamisa isikhalo sazo.
Izici ze-MIFARE DESFire Cards
Amakhadi e-DESFire afakwe izici ezichaza kabusha izinhlelo zokusebenza zobuchwepheshe be-proximity. Kusukela ebangeni elinwetshiwe lokuxhumana lokuthenga ngokushesha kuya kuma-Rolling Keysets awo aphambili kanye ne-Proximity Identification, lawa makhadi asebenzisa ubuchwepheshe obungcono kakhulu ukuletha inani. Ukwengeza, i-DESFire EV2 inikeza ukuphathwa kokhiye abalinganisiwe, okuvumela ukwenza inkontileka encane okuvikelekile ezinkampanini zangaphandle ngaphandle kwesidingo sokwabelana ngokhiye oyinhloko wekhadi.
Ukusetshenziswa kwamakhadi we-MIFARE DESFire
MIFARE DESFire amakhadithola izinhlelo zokusebenza emikhakheni eyahlukene ngenxa yokuguquguquka kwazo. Ukusebenza kwawo kusuka ekuthengeni amathikithi ezithuthi zomphakathi, ukuphathwa kokufinyelela okuvikelekile, kanye namathikithi emicimbi kuya kumasistimu okukhokha nge-e-loop evaliwe kanye nezicelo ze-eGovernment. Amandla abo okwenza lula ukusebenza kanye nokwenza ngcono ulwazi lwabasebenzisi kulezi zindawo kubenza babe ithuluzi elibalulekile lengqalasizinda yesimanje.
I-QC PASS ngaphambi kokulethwa kwe-MIFARE DESFire Cards
Ikhadi ngalinye le-MIFARE DESFire lingaphansi kokuhlolwa okujulile kwe-QC PASS ngaphambi kokuthunyelwa. Le nqubo iqinisekisa ukuthi ikhadi ngalinye lifinyelela izindinganiso zekhwalithi ezimisiwe mayelana nokubukeka, ukusebenza, nokwethembeka. Isiqubulo esibalulekile lapha siwukuqinisekisa ukuthi ikhadi lisiza ikhasimende ngokungenaphutha esikhathini esiphila kulo.
CXJSMART MIFARE DESFire Cards
Amakhadi e-CXJSMART MIFARE DESFire anweba isithembiso sekhwalithi, ukuguquguquka, nokuvikeleka isiko le-MIFARE elisigcinayo. Ngokuthuthukiswa kwebanga lokuxhumana, ukuthuthuka ekuvikelekeni kwedatha, kanye nokufakwa kwezici ezintsha ezifana ne-Rolling Keysets kanye ne-Proximity Identification, lawa makhadi anikeza isixazululo esibanzi sezinhlelo zokusebenza ezihlukahlukene zobuchwepheshe bokusondela.
Amakhadi we-MIFARE DESFire Asezingeni eliphezulu
Ikhwalithi iyipharamitha engaxoxiswana ngayo yamakhadi we-MIFARE DESFire. Ikhadi ngalinye, ngokunganaki ukwahluka kwalo, liqinisekisa amakhasimende ukuqina, ukusebenza okungenasici, nokuphepha okuqinile. Kungakhathaliseki ukuthi ukwakheka kwekhadi, idizayini, noma ukusebenza, ukuzibophezela kukhwalithi ephezulu akuntengantengi. Lawa makhadi ekhwalithi ephezulu aqinisekisa ukuthi abasebenzisi bathola isevisi ethembekile ngaso sonke isikhathi. Sengiphetha, amakhadi e-MIFARE DESFire, ikakhulukazi i-EV1 ne-EV2, aguqule indlela amabhizinisi, ohulumeni, nabathengi ababhekana ngayo nokuthengiselana okuvikelekile kwedatha nokulawula ukufinyelela. Ngezici zawo ezihlakaniphile, ukusebenza okuthuthukisiwe, nokuphepha okuthuthukisiwe, lawa makhadi anikeza inani elikhulu kubasebenzisi kuyo yonke imikhakha ehlukahlukene. Njengabahlinzeki bala mathuluzi aphambili, thina kwaCXJSMART sizibophezele ekuletheni Amakhadi wekhwalithi ephezulu we-MIFARE DESFire ahlangabezana nezidingo ezahlukahlukene zamakhasimende ethu.
