Ukuqonda Izisekelo Zobuchwepheshe Bekhadi Le-Smart
Amatheminali okukhokha namasistimu omazisi ashintshile indlela esiphatha ngayo imisebenzi evikelekile kanye nokulawula ukufinyelela ezinhlelweni zokukhokha zanamuhla. Lawa madivayisi athuthukile axhuma i-chip yekhadi lakho elihlakaniphile emhlabeni wedijithali. Bavumela ukuxhumana okushelelayo ezintweni eziningi, njengezithuthi zomphakathi, indawo yokupaka, kanye nemisebenzi yezezimali.
Iyini Idivayisi Yokukhokha Yekhadi Elihlakaniphile?
Iyunithi yesixhumi esibonakalayo sekhadi elihlakaniphile isistimu ye-elekthronikhi exhumana namakhadi ahlakaniphile aqukethe amasekhethi ahlanganisiwe ashumekiwe. Ungathola lawa matheminali okuqinisekisa ngezinhlobo ezahlukene.
Zisuka kumadivayisi amancane e-USB kuye kumasistimu enethiwekhi athuthukile. Lezi zinhlelo zisetshenziswa kuma-validators amabhasi namamitha okupaka. E-Golong, sisebenza ngokukhethekile ekukhiqizeni izimboni-amaphrosesa ekhadi le-chip anika amandla amasistimu okuhlanganisa izinkokhelo anokwethenjelwa ezokuthutha zomphakathi.
Indlela I-Smart Card Interfaces Esebenza ngayo: Inqubo Yobuchwepheshe
Oxhumana naye vs. Ukuxhumana Okungenantambo
Amasistimu wokuqaphela ama-chip asebenza ngezindlela ezimbili eziyinhloko:
Amayunithi - Asekelwe Oxhumene Naye: Lokhu kudinga ukufakwa ngokomzimba kwekhadi endaweni yedivayisi. Oxhumana nabo bensimbi ku-chip yekhadi baxhuma ngqo kuzixhumi zetheminali. Lokhu kuvumela ukudluliswa kwedatha okuvikelekile ngesivinini esingafika ku-424 Kbps.
Amadivayisi Okukhokha Ngaphandle Kokuthinta: Ngokusebenzisa ubuchwepheshe befrikhwensi yerediyo (RF), lezi zikhungo ezingenantambo zixhumana nge-RFID noma izivumelwano ze-NFC. Uma ikhadi lifika phakathi kuka-50mm weyunithi yokutholwa, linika amandla i-chip yekhadi. Lokhu kuqala ukushintshana kwedatha.
I-Communication Protocol
Umgomo wokusebenza ulandela inqubo ejwayelekile:
- Ukusebenzisa Amandla: Idivayisi yesixhumi esibonakalayo ikhiqiza inkambu ye-electromagnetic eyenza i-chip yekhadi isebenze
- Ukuqinisekisa: Amaphrothokholi avikelekile aqinisekisa ubuqiniso bekhadi usebenzisa ukuxhumana okubethelwe
- Ukuhwebelana Ngedatha: Ulwazi lugeleza phakathi kwekhadi neyunithi yokucubungula ngezivumelwano ezimisiwe ezifana ne-ISO 14443 yamakhadi angathintwa
- Ukucutshungulwa kokwenziwayo: Itheminali icubungula idatha etholiwe futhi ixhumana nesistimu yokusingatha
Izingxenye Zobuchwepheshe Bekhadi Le-Smart
Ngaphakathi kweSmart Card
Amakhadi ahlakaniphile esimanje aqukethe izinto ezimbalwa ezibalulekile:
- I-Microprocessor: Iphatha ukucutshungulwa kwedatha kanye nama-algorithms okuphepha
- Isitoreji Senkumbulo: Igcina phakathi kuka-1,000 kuya ku-256,000 amayunithi edatha (okungaphezulu kakhulu kwamakhadi omugqa kazibuthe)
- Ikhoyili ye-Antenna: Ivumela ukuxhumana okungenantambo emakhadini angenantambo
- Amaphedi Okuxhumana: Nikeza uxhumano lukagesi kumakhadi asekelwe kokuxhumana
Hardware Imininingwane
Izifundi zokuhlonza ezingochwepheshe, njengalezo ezikhiqizwe i-Golong, zinesici:
- Multi-protocol Support: Ihambisana ne-FeliCa, NFC, kanye namazinga e-ISO 14443 Type A/B
- Ibanga Elinwetshiwe Lokufunda: Kufika ku-50mm ekusebenzeni ngaphandle kokuthintwa
- I-USB 2.0 Interface: Iqinisekisa ukuxhumana okuthembekile namasistimu okusingatha
- Ukuthobela I-PC/SC: Isekela imboni-izimiso zokuxhumana ezijwayelekile
Izicelo Ezinhlelweni Zokuthutha Zomphakathi Nezokukhokha
Amasistimu Wokuqinisekisa Ibhasi
Iziqinisekisi zezokuthutha zisebenza njengengxenye eyinhloko ezinhlelweni zesimanje zamathikithi amabhasi. Lawa maphrosesa aqinile amelana nezimo zemvelo ezinzima ngenkathi ecubungula izinkulungwane zemisebenzi nsuku zonke. Amatheminali asekela izindlela zokukhokha eziningi ezihlanganisa amakhadi-amanani agciniwe, izinkokhelo zeselula, nezimali zedijithali.
Ukuhlanganiswa Kwemitha Yokupaka
Kuzinhlelo zokusebenza zokupaka, amadivaysi okukhokha azenzakalelayo anika amandla ukucubungula okwenziwayo okulula ngenkathi egcina amarekhodi avikelekile. Ubuchwepheshe busebenza nezinhlobo ezahlukene zamakhadi. Iphinde ixhume kalula ezinhlelweni zokuphatha zokuqapha kwangempela-isikhathi kanye nokuhlaziya idatha.
Ukulawula Ukufinyelela Nokuphepha
Ngaphandle kokucutshungulwa kwenkokhelo, izixhumanisi zokulawula ukufinyelela zihlinzeka ngokuphathwa kokungena okuphephile kwezindawo ezikhawulelwe, ukulandelela ukuba khona kwesikhathi, kanye nezinhlelo zokuqinisekisa ubuwena. Ukuxhumana okubethelwe kuqinisekisa ubuqotho bedatha futhi kuvimbela ukufinyelela okungagunyaziwe.
