NFC VS RFID: Dab tsi yog qhov txawv thiab uas xaiv

Lub hauv paus rau phau ntawv

Thaum sourcing cov cuab yeej hnav los yog cov ntim cov khoom sib ntse, cov neeg yuav khoom feem ntau ntsib cov lus nug uas nquag muaj:Kuv puas yuav siv NFC lossis RFID?Txawm hais tias ob qho tib si thev naus laus zis cia siab rau kev txheeb xyuas xov tooj cua ntev, lawv ua lub hom phiaj sib txawv. Nkag siab txog qhov sib txawv tuaj yeem pab koj xaiv cov kev daws teeb meem rau koj txoj kev lag luam.

RFID yog dab tsi?

RFID (xov tooj cua siv hluav taws xob) siv hluav taws xob) siv cov xov tooj cua ntawm xov tooj cua los txheeb xyuas thiab taug qab cov khoom. Nws los nyob rau hauv peb zaus ntau npaum li cas:

LF (tsawg zaus)- Luv luv, siv hauv tsiaj cim npe.

HF (siab siab)- 13.56 MHz, ib txwm nyob rau hauv lub tsev qiv ntawv, nkag mus khomob.

UHF (ultra - siab} siab siab)- Ntev ntev nyeem ntau, siv nyob rau hauv logistics thiab muab cov saw hlau.

NFC yog dab tsi?

NFC (ze ntawm kev sib txuas lus) yog aSubset ntawm HF RFID, optimized rauLuv - deb, ob {{1} {txoj kev sib txuas lusCov. Nws yog dav siv nyob rau hauv cov ntawv thov cov ntawv thov xws li tsis muaj kev them nyiaj, kev sib tham hauv xov tooj cua, thiab hnav dab teg.

Qhov sib txawv tseem ceeb ntawm NFC thiab RFID

Qho deb

RFID: Los ntawm ob peb centimeters (LF / HF) mus txog 10+ meters (UHF).

NFC: Feem ntau tsis pub dhau 1-5 cm.

Kev sib txuas lus

RFID: Feem ntau ib - txoj kev (nyeem ntawv rau tag).

NFC: Ob {{{- txoj kev (TAG ↔ smartphone los yog nyeem ntawv).

Kua roj

RFID: Yuav tsum muaj kev nyeem ntawv siab.

NFC: Ua haujlwm ncaj qha nrog smartphones.

Cov Ntawv Thov

RFID: Cov Lus Qhia Kev Taug Xyuas, Khoom Siv Khoom Siv Khoom Siv, Logistics.

NFC: Wristbands rau cov xwm txheej, ntse ntim, nyiaj them tsis tau nyiaj.

Koj yuav xaiv qhov twg?

Cov FAQ

Q1: Puas NFC thiab RFID yuav siv ua ke?
A: Yog. Piv txwv li, ib qho kev tshwm sim tej zaum yuav siv UHF RFID rau logistics thiab NFC Wristbands rau kev tuaj koom.

Q2: Cov pheej yig dua?
A: Cov ntawv yooj yim RFID tuaj yeem pheej yig dua nyob rau hauv ntau, tab sis NFC ntxiv ntau sib tham sib.

Q3: NFC puas ruaj ntseg?
A: Yog, NFC txhawb kev phiv tshuaj encryption, ua rau nws haum rau kev them nyiaj thiab kuaj xyuas.
