Ikhadi lepulasitiki elenziwe ngokwezifiso le-PVC NFC MIFARE Ultralight C

I-MIFARE Ultralight® C engathinteki IC iyisixazululo esingabizi kakhulu kusetshenziswa indinganiso evulekile ye-cryptographic ye-3DES yokuqinisekisa i-chip nokufinyelela idatha.

Izinga elamukelwa kabanzi le-3DES livumela ukuhlanganiswa kalula kungqalasizinda ekhona futhi isethi yomyalo ohlanganisiwe wokuqinisekisa inikeza ukuvikelwa okusebenzayo kwe-cloning okusiza ukuvimbela amathegi mbumbulu.

Amathikithi, amavawusha noma omaka abasuselwe ku-MIFARE Ultralight C bangasebenza njengamathikithi ohambo olulodwa, amathikithi omcimbi noma njengamakhadi okwethembeka abiza kancane futhi asetshenziselwa ukufakazela ubuqiniso bedivayisi.

   • Ukushumeka i-antenna kanye ne-MIFARE Ultralight C chip phakathi nenqubo yokucwenga kuqinisekisa ukuhlanganiswa okungenamthungo.
3. Ukushumeka kwe-Chip:
   • I-MIFARE Ultralight C contactless IC, eyaziwa ngezinga layo le-3DES cryptographic, ishumekwe ngokunembile ekhadini.
   • Inqubo yokushumeka ibandakanya ukuqinisekisa ukuthi i-chip ihambisana ne-antenna ukuze isebenze kahle.
4. Ukusika:
   • Izinto ezilayiniwe zisikwa ngosayizi wekhadi le-CR80 elijwayelekile.
   • Amathuluzi okusika anembe kakhulu asetshenziselwa ukuqinisekisa ukunemba kobukhulu, okubalulekile ekusebenzisaneni nezifundi zamakhadi namaphrinta.
5. Ukuphrinta:
   • Amakhadi aphrintwa ngemiklamo eyenziwe ngokwezifiso kusetshenziswa amaphrinta wekhadi lokudlulisa elishisayo noma elishisayo.
   • Amasu okuphrinta akhethwa ngokusekelwe ebunkingeni bomklamo odingekayo kanye nokuqina.
6. Ukufakwa Kwekhodi Kwedatha:
   • Idatha ethile ifakwe ikhodi ku-chip ye-MIFARE Ultralight C ngokwezidingo zekhasimende.
   • Umbhalo wekhodi uhlanganisa ukusetha okhiye be-cryptographic kanye nokucacisa imiyalo yokufinyelela yokuvikela idatha.

1. Ukuhlola Okubalulekile:
   • Ukuhlolwa kokuqala kwamashidi e-PVC/PET ukuze kutholakale amaphutha noma ukungahambisani.
   • Ukuqinisekisa ukuthi izinto ezisetshenziswayo zihlangabezana namazinga embonini ngaphambi kokuqala kokukhiqiza.
2. Ukuhlola Ukusebenza Kwe-chip:
   • I-chip ngayinye ye-MIFARE Ultralight C ihlolelwa ukusebenza ngaphambi kokushumeka.
   • Ukuhlola kufaka phakathi ukuqinisekisa ukuqinisekiswa kwe-3DES nemiyalo yokufinyelela idatha.
3. Ukuhlola Ukuhambisana:
   • Amakhadi ayahlolwa ukuze kuqinisekiswe ukuthi athobelana ngokugcwele namazinga e-ISO/IEC 14443 A 1-3 kanye ne-NFC Forum Type 2 Tag.
   • Ukuqinisekiswa kosekelo lokungashayisani kanye nesivinini sokuxhumana esingu-106 Kbit/s.
4. Ukulawulwa Kwekhwalithi Ye-Antenna:
   • Ukuqinisekisa ukuxhumana okufanele phakathi kwe-antenna ne-chip eshumekiwe.
   • Ukunciphisa ukulahleka kwesignali nokuqinisekisa amakhono angaguquki okufunda/okubhala.
5. Ukuhlola Ukuqina:
   • Amakhadi ahlolwa ngomshini ukuze aqinisekise ukuthi angakwazi ukumelana nokusetshenziswa okuvamile ngaphandle kokuwohloka.
   • Ukuhlola ukuqina kwamakhadi, okuhlanganisa amandla e-chip okusebenza ngemva kokusebenza kokubhala okukodwa okungu-10,000.
