Nangahe uzi kuri NFC na RFID?

Igitekerezo cya NFC

Izina ryuzuye rya NFC ni Hafi yumurongo witumanaho, itumanaho rito. NFC ni tekinoroji idafite umugozi yatangijwe na Philips kandi igatezwa imbere na Nokia, Sony nabandi bakora ibicuruzwa bizwi. NFC yatejwe imbere hashingiwe ku buhanga bwa radiyo idahuza iranga (RFID) hamwe na tekinoroji yo guhuza imiyoboro. Ubu buhanga muburyo bwambere bwo guhuza gusaIkoranabuhanga rya RFIDn'ikoranabuhanga ry'urusobekerane, ubu byahindutse muburyo bwa tekinoroji ya terefone itumanaho, kandi iterambere ryayo ryihuta cyane.

Igitekerezo cya RFID

RFID ni impfunyapfunyo ya Radio Frequency Identification, izwi kandi nka tagi ya elegitoronike, ni tekinoroji itamenyekana itagaragara. Irerekana intego yihariye ikoresheje ibimenyetso bya radio kandi isoma kandi yandika amakuru ajyanye nta mashini cyangwa optique ihuza intego. Ntabwo bisaba kwifashisha intoki, birashobora gukoreshwa mubidukikije bitandukanye bikaze, birashobora kumenya ibintu byihuta byihuta, bishobora kumenya ibimenyetso byinshi icyarimwe, kandi ibikorwa birihuta kandi byoroshye.

Itandukaniro hagati ya NFC na RFID

Urutonde rutandukanye

Imikorere ya RFID ni nini cyane. Bikunze gukoreshwa ni 125KHZ na 133KHZ (inshuro nke), 13.56MHZ (inshuro nyinshi), 900MHZ (ultra-high frequency ), 433MHZ, 2.4G, 5.8GMHZ (inshuro ya microwave). Mubyongeyeho, UHF 900M nayo ni ijambo rusange, ntabwo ariryo ryukuri. Inshuro nazo ziratandukanye bitewe nigihugu. Kurugero, itsinda ryumurongo wiburayi (865.6MHZ-867.6MHZ), Singapore (920MHz ~ 925MHz), Ubushinwa (920.5MHZ-924.5MHZ cyangwa 840.5MHZ-844.5MHZ), Amerika (902M-928M), Berezile (902M- 907.5M cyangwa 915M- 928M), n'ibindi.

Imikorere ya NFC ni 13.56MHZ gusa. Turashobora no gusobanukirwa NFC nkigice cya tekinoroji ya RFID, ikoresha umurongo wa 13.56MHz nitsinda ryihariye rya HF RFID. Porogaramu yiyi bande irazwi cyane, kandi irimo protocole zitandukanye. Ariko 13.56MHZ ntabwo bivuze ko byose bihwanye na NFC.

Intera itandukanye

Kuberako RFID ifite umwanya munini wo gukora inshuro, intera yoherejwe kuri radiyo zitandukanye nazo ziratandukanye. Igufi ni santimetero nkeya, kandi ndende irashobora kugera kuri metero nyinshi cyangwa na metero mirongo.

NFC ni tekinoroji yo gutumanaho intera ndende. Nkuko izina ribigaragaza, intera yoherejwe ni ngufi, mubisanzwe muri 20cm, kugirango itumanaho ribe ryiza. Ibi biterwa ahanini na tekinoroji yihariye yerekana ibimenyetso byemejwe na NFC, ifite ibiranga intera ngufi, umuvuduko mwinshi hamwe n’ingufu nke.

Ikoranabuhanga ritandukanye

Sisitemu y'itumanaho yose ya RFID igizwe naIbiranga RFID , antene hamwe nabasomyi ba RFID, byose ni ngombwa. Sisitemu ikeneye gusoma no guca imanza amakuru atabigenewe binyuze mubasomyi.

NFC ihuza abasomyi, ikarita itagira aho ihurira hamwe n-ingingo-ku-ngingo-imwe muri chip imwe, hamwe na terefone ebyiri zigendanwa cyangwa ibikoresho bishobora kwambarwa byubatswe muri NFC birashobora kumenya imikoranire yamakuru hafi. Itandukaniro mu ikoranabuhanga mu itumanaho ni itandukaniro rinini hagati yombi. NFC ni intera ngufi uburyo bwo gutumanaho bwigenga.

Itandukaniro naryo riganisha kubitandukanya mubyo basaba. Urebye ibyerekeranye no gusaba, birashobora kugaragara ko hari itandukaniro rigaragara hagati ya RFID na NFC. RFID ni ibintu-bishingiye, mugihe NFC ikoresha-kandi isaba uruhare rwabakoresha kugirango bagere kubikorwa. RFID imenya gusoma no guca amakuru, mugihe tekinoroji ya NFC ishimangira imikoranire yamakuru hamwe byoroshye kandi byombi.

Mubikorwa bifatika, RFID irashobora gutuma umusomyi asoma umubare munini waIbirango bya RFID icyarimwe, bikunze kugaragara cyane mububiko. RFID ikoreshwa kenshi mubikoresho, gucuruza, indege, ubuvuzi, gucunga umutungo. Indangamuntu yo mu gisekuru cya kabiri hamwe namatike ya Olempike ya Beijing byose byubatsweImashini ya RFID, hamwe na ETC sisitemu yo gukusanya imisoro idahagarara kuri gari ya moshi nayo ikoresha tekinoroji ya RFID.

NFC muri rusange ni imwe-imwe, kandi intera yoherejwe ya NFC ni nto cyane ugereranije na RFID. Kubwibyo, NFC igira uruhare runini mubijyanye no kugenzura uburyo bwo gutwara abantu, gutwara abantu, no kwishyura kuri terefone.

Mubyukuri, porogaramu ya RFID ni nini cyane kuruta NFC, ndetse dushobora kuvuga ko RFID irimo NFC. Ariko, kubera itandukaniro ryimiterere yimikorere hagati ya RFID na NFC, byombi ntabwo bigize umubano wo guhatana, ahubwo bigira uruhare mubitekerezo byabo byahujwe. Nubwo ikoranabuhanga ryakoreshwa gute, ikibazo gikomeye ni ugutekereza uburyo bwo kunoza uburambe bwabakoresha no kuzana ibyoroshye kubakoresha.
