MIFARE DESFIRE EV2 2K 4K 8K Blank RFID Card
Khadi la MIFARE DESFire EV2 2K 4K 8K RFID limayimira ukadaulo wapamwamba kwambiri wamakhadi anzeru.
Kupereka chitetezo chapamwamba komanso kusinthasintha, zinthu izi za NXP MIFARE zimapereka chitetezo chamabizinesi okhala ndi kuthekera kophatikizana kopanda malire pakuwongolera kwamakono komanso kugwiritsa ntchito bwino mzindawu. M'nkhaniyi, tikambirana za mawonekedwe, ubwino,
ndi ukadaulo wa MIFARE DESFire EV2, wopereka chiwongolero chokwanira kwa ogwiritsa ntchito.
Chidule cha Zamalonda ndi Ubwino
MIFARE DESFire EV2 imagwira ntchito pafupipafupi 13.56MHz ndipo idapangidwa kuti ikwaniritse miyezo yapamwamba kwambiri yachitetezo.
Imapezeka m'mitundu itatu yokumbukira: 2K, 4K, ndi 8K byte, yopereka zosowa zosiyanasiyana zosungira.
Kubisa kwapamwamba kwa khadi ndi chitetezo champhamvu kumapangitsa kuti ikhale yabwino kwa mapulogalamu omwe amafunikira chitetezo chapamwamba kwambiri.
Ubwino waukulu
- Chitetezo Chowonjezera: Ndi njira zapamwamba zolembera monga DES, 2K3DES, 3K3DES, ndi AES, MIFARE DESFire EV2 imatsimikizira kutumiza ndi kusunga deta motetezeka.
- Kusinthasintha: Ndikoyenera kugwiritsa ntchito zosiyanasiyana, kuphatikiza kuwongolera njira, zoyendera za anthu onse, zolipirira pa intaneti, ndi mapulogalamu okhulupilika.
- Kuphatikiza Kopanda Msoko: Kugwirizana kwathunthu ndi miyezo ya ISO14443-A ndi NFC Type 4, kuwonetsetsa kuti ikugwirizana ndi zida zowerengera za NFC zomwe zilipo.
- Kuchita Kwapamwamba: Kusamutsa deta mwachangu komanso kukumbukira kwambiri kumapangitsa kukhala koyenera madera ovuta.
Zolemba Zamalonda
1. MwaukadauloZida Security Mbali
Chitetezo ndichofunika kwambiri pamapangidwe a MIFARE DESFire EV2.
Khadiyo imaphatikizapo ma injini a cryptographic ozikidwa pa Hardware, kutsimikizika kwamapasi atatu,
ndi ma protocol otetezedwa a data. Ilinso ndi chiphaso cha Common Criteria EAL5 + chitetezo,
kuwonetsetsa chitetezo chapamwamba kwambiri ku zigawenga zapamwamba.
2. Zosankha pa Memory: 2K, 4K, ndi 8K
MIFARE DESFire EV2 imapezeka m'mitundu itatu yokumbukira: 2K, 4K, ndi 8K byte. Kusinthasintha kumeneku kumathandizira ogwiritsa ntchito kusankha malo oyenera osungira pazosowa zawo zenizeni, kaya ndi njira zosavuta zowongolera kapena zovuta zamapulogalamu ambiri.
3. Kutsatira ISO14443-A ndi NFC Type 4
Khadiyo imagwirizana kwathunthu ndi miyezo ya ISO14443-A ndi NFC Type 4, ndikupangitsa kuti ikhale yogwirizana ndi owerenga ambiri a NFC komanso zomangamanga. Izi zimatsimikizira kusakanikirana kosasinthika ndi kugwirizana ndi machitidwe amakono.
4. Fast Data Transfer Rates
MIFARE DESFire EV2 imathandizira kusamutsa deta mpaka 848 kbps, kuwonetsetsa kulumikizana mwachangu komanso koyenera pakati pa khadi ndi owerenga. Izi ndizofunikira pamapulogalamu omwe amafunikira kukonzedwa mwachangu komanso kugwiritsa ntchito kwambiri.
5. Mapangidwe Olimba Ndi Okhazikika
Khadiyo idapangidwa kuti ipirire malo ovuta komanso kugwiritsidwa ntchito pafupipafupi. Amapereka nthawi yosungira deta ya zaka 25 ndi kupirira kwa kulemba kwa 500,000, ndikupangitsa kukhala chisankho chodalirika cha ntchito za nthawi yaitali.
6. Thandizo Logwiritsa Ntchito Zambiri
MIFARE DESFire EV2 imathandizira kugwiritsa ntchito kangapo pa khadi limodzi, chifukwa cha mawonekedwe ake osinthika amafayilo komanso kuthekera koyang'anira ntchito. Izi zimapangitsa kukhala koyenera kwa ntchito zamatawuni zanzeru, pomwe khadi limodzi litha kugwiritsidwa ntchito pamayendedwe apagulu, kuwongolera mwayi wofikira, kulipira pakompyuta, ndi zina zambiri.

Malangizo Ogwiritsa Ntchito
Kuti mugwiritse ntchito MIFARE DESFire EV2, ingoperekani khadi kwa owerenga omwe amagwirizana ndi NFC. Makhadi achitetezo apamwamba achitetezo amathandizira kutsimikizika ndi njira zotumizira deta, kuwonetsetsa kulumikizana kotetezeka komanso koyenera.
Environmental Impact
MIFARE DESFire EV2 idapangidwa ndikukhazikika mumalingaliro. Kutalika kwa moyo wa khadi ndi kulimba kwambiri kumachepetsa kufunika kosintha pafupipafupi, kuchepetsa zinyalala. Kuphatikiza apo, kudzipereka kwa NXP pakupanga njira zokondera zachilengedwe kumatsimikizira kuti kupanga makhadiwa sikukhudza chilengedwe.
Ndemanga za Makasitomala
Makasitomala adayamika MIFARE DESFire EV2 chifukwa chodalirika, chitetezo, komanso kusinthasintha. Ogwiritsa ntchito ambiri adawunikira mitengo yosinthira deta yachangu komanso yopanda msoko
Lembani uthenga wanu apa ndikutumiza kwa ife
