Feem ntau cov xov tooj ntawm tes tsis tuaj yeem nyeem cov cim RFID ib txwm muaj ncaj qha, masntau lub xov tooj niaj hnub no tuaj yeem nyeem ib hom RFID hu ua NFC (Nyob ze rau kev sib txuas lus)- uas yog tus txheeb ze ze ntawm RFID.
Qhov tseem ceeb sib txawv & Muaj peev xwm
| Feature | Ib txwm RFID | NFC (hauv Smartphones) |
|---|---|---|
| Ntau zaus | LF (125 kHz), HF (13.56 MHz), UHF ({2}}-960 MHz) | HF nkaus xwb: 13.56 MHz |
| Ntau yam | Txog li ob peb meters (tshwj xeeb tshaj yog UHF) | luv heev: ~ 4 cm (1.5 nti) |
| Ob- txoj kev sib txuas lus | Feem ntau ib -txoj kev (tag → nyeem) | Yog, ob-txoj kev |
| Pom hauv smartphones? | ❌ Tsis muaj RFID nyeem ntawv tshwj xeeb | ✅ Cov xov tooj niaj hnub no feem ntau muaj NFC |
Dab tsi koj lub xov tooj tuaj yeem nyeem nrog NFC
Koj lub smartphone (yog tias nws muaj NFC) tuaj yeem cuam tshuam nrog:
NFC tag(siv hauv cov ntawv tshaj tawm ntse, tsev automation)
Contactless credit/debit cards(Apple Pay, Google Pay)
Access paib(qee qhov chaw ua haujlwm keycards)
Ntse nra tag
Daim ntawv hla tebchaws(nrog cov apps tshwj xeeb thiab kev tso cai)
Nco tseg: Tsis yog tag nrho cov cim RFID yog NFC- tau tshaj. Muaj ntau daim npav nkag lossis cov ntawv teev npe sivLF lossis UHF RFID, koj lub xov toojnyeem tsis tautsis muaj lwm yam khoom siv.
Yuav kuaj xyuas seb koj lub xov tooj puas muaj NFC
iPhone:
iPhones los ntawmiPhone 6 thiab tshiab duatxhawb NFC.
Tag nrho cov ntawv nyeem / sau ntawv muaj txij li thaumiPhone 7+(nrog iOS no 11+).
Qhib lubShortcuts applos yog siv thib peb- tog apps xws li "NFC cuab yeej."
Android:
Feem ntau Android xov tooj los ntawm2012 tom ntej nosuav nrog NFC.
Saib rau lub cim NFC hauv kev teeb tsa lossis hauv qab "Cov khoom siv txuas nrog."
Siv cov apps zoo li"NFC cuab yeej"los yogGoogle Them.
Koj puas tuaj yeem ua lub xov tooj nyeem tsis yog -NFC RFID?
Yog - tab sis tsuas yog nroghardware sab nraud:
Plug-hauv RFID nyeem ntawv (ntawm USB-C/ xob laim)
Bluetooth- txuas nrog RFID scanners
Smart card nyeem ntawv uas cuam tshuam nrog koj lub xov tooj ntawm apps
Tej no cia koj nyeemLF (125 kHz)los yogUHF RFID cim npetias koj lub xov tooj tau tsim -hauv NFC nti tsis tuaj yeem ntes tau.
Cov ntsiab lus
✅ Yog lawm- Koj lub xov tooj tuaj yeem nyeem tauNFC tag(ib pawg ntawm HF RFID).
❌ Tsis muaj- Nws tsis tuaj yeem nyeem feem ntautsoos RFID(xws li UHF warehouse tags lossis standard access cards) tshwj tsis yog koj ntxiv cov khoom siv sab nraud.
Yog li ntawd thaumCov xov tooj ntawm tes tsis nyeem tag nrho RFID, lawv txhawb kev sib raug zoo, siv dav siv tshuab:NFC.
