Waba uzi interineti yibintu biranga ikoranabuhanga: Ni irihe tandukaniro riri hagati ya RFID na NFC?

Internet y'ibintu igizwe nihanga ryikoranabuhanga rito: guhuza, kumenyekanisha no gukoresha amakuru

Nfc

Hafi yo gutumanaho kumurima (NFC). NFC numurongo rusange witumanaho kuri terefone zigendanwa. Ibikoresho byubwenge birashobora guhana amakuru urebye. Ibikoresho bya NFC birashobora kandi kuvugana na pasiporo ya NFC. Uburyo bwo gutumanaho ni kimwe na RFID. Usibye protocole itumanaho, ibipimo bya NFC byerekana imiterere yo guhana amakuru. Sonsed Ikarita Yikarita Yabasomyi, ikarita ya sensor hamwe ningingo-kugeza kuri chip imwe ya nfc kubiranga no guhana amakuru hamwe nibikoresho bihuje hejuru yimbuga ngufi.

Kumenyekanisha radiyo

Kumenyekanisha radiyo idahuye (RFID) mubyukuri ikoranabuhanga mu itumanaho ritagira umugozi kandi risobanura amakuru binyuze muri Wireless ElecHonagnetic Imiraba. Ariko, bitandukanye nikoranabuhanga risanzwe mu itumanaho, intego ntabwo ari uguhamagara kuri terefone cyangwa ohereza ubutumwa bugufi. RFID ikoreshwa cyane mu kumenya no gukurikirana ibirango bihambiriye ikintu, kugirango ugere ku micungire y'ibintu.

Itandukaniro riri hagati ya NFC na RFID

1. Imirongo ikora

NFC irashobora kumvikana nkikipe yikoranabuhanga rya RFID rikoresha itsinda rya 13.56mhz, na RFID nayo ikubiyemo andi matsinda.

RFID ifite imirongo myinshi yakazi, itsinda rito ni 125khz, itsinda ryinshi riri 13.56mhz, itsinda rya dointra-Hejuru ni 433.9mhz, hamwe na Microwave Bandes 2.45ghz.

2. Intera itumanaho

NFC yitwa hafi itumanaho ryumurima, kandi intera yo gutumanaho mubyukuri iri hafi, bitarenze 0.1m.

Hariho ubwoko bwinshi bwa RFID, intera iranga nayo iratandukanye. Nkamakarita ya RFID ya RFID, intera yo kumenyekana iri hafi na NFC. Ariko, kubisabwa byabigenewe nkibi nibindi, intera ndende irakenewe. Intera ndangamuntu yintera ndende rfid irashobora kugera kuri metero icumi cyangwa hamwe na metero amagana.

3. Scenarios

Niba RFID ikora cyangwa pasiporo, akazi kayo nyamukuru karacyariho kumenya ibintu. Ibikoresho, ubwikorezi nububiko Koresha tekinoroji ya RFID kugirango ukurikirane ibicuruzwa.

Chip ya NFC irahujwe, harimo abasomyi bakarita na Tags. Byongeye kandi, ubushobozi bwitumanaho bubiri bwa NFC bwazamuwe. Muyandi magambo, NFC irashobora gukoreshwa nka tagi iranga gusa, ariko nayo nuburyo bwo gutumanaho bubiri bwo guhana amakuru. Kugeza ubu, NFC ikoreshwa cyane muri domaine yo kwishyura.
