Yini i-NFC? Ngamagama alula, ngokuhlanganisa imisebenzi ye-inductive card reader, ikhadi le-inductive kanye nokuxhumana kwephuzu nephuzu ku-chip eyodwa, amatheminali eselula angasetshenziswa ukufeza inkokhelo yeselula, amathikithi e-elekthronikhi, ukulawula ukufinyelela, ukuhlonza ubunikazi beselula, ukulwa nokukhwabanisa. nezinye izinhlelo zokusebenza. Kunabakhiqizi abaningana abaziwayo be-chip ye-NFC e-China, ikakhulukazi abafaka i-Huawei hisilicon, i-Unigroup Guoxin, i-ZTE Microelectronics, i-Fudan Microelectronics njalonjalo. Lezi zinkampani zinezinzuzo zazo zobuchwepheshe kanye nezikhundla zemakethe emkhakheni we-NFC chips. I-Huawei hisilicon ingenye yezinkampani ezinkulu zokuklama ama-chip zokuxhumana e-China, futhi ama-chips ayo e-NFC aziwa ngokuhlanganisa okuphezulu nokusebenza okuzinzile. I-Unigoup Guoxin, i-ZTE Microelectronics ne-Fudan Microelectronics nazo zisebenze ngokugqamile ekuvikelekeni kwenkokhelo, amandla okucubungula idatha kanye nezimo zezicelo eziningi, ngokulandelana. Ubuchwepheshe be-NFC busekelwe kuphrothokholi yokuxhumana okungenantambo engu-13.56 MHz futhi yenza ukuxhumana okungenantambo phakathi kwamadivayisi amabili anikwe amandla yi-NFC aqhelelene ngamasentimitha angu-10. Kulula kakhulu, lokhu kuxhumana akuncikile ku-Wi-Fi, 4G, LTE noma ubuchwepheshe obufanayo, futhi akubizi lutho ukukusebenzisa: akukho makhono omsebenzisi adingekayo; Alikho ibhethri elidingekayo; Awekho amaza e-RF akhishwayo lapho isifundi sekhadi singasetshenziswa (ubuchwepheshe be- passive); Ngokuduma kobuchwepheshe be-NFC kumafoni ahlakaniphile, wonke umuntu angajabulela izinzuzo ze-NFC.
