Ntawm no yog ibkauj ruam -los ntawm - kauj ruam qhialos pab koj txiav txim seb koj tus fob tseem ceeb puas yogNFC los yog RFID. Ob qho no yog cov cuab yeej sib txuas, tab sisNFC yog hom HF (siab-frequency) RFIDnrog rau cov qauv tshwj xeeb rau mobile thiab luv -kev sib txuas lus.
1. Txheeb xyuas qhov zaus
RFID tuaj rau hauvpeb lub ntsiab zaus ntau zaus:
| Hom | Ntau zaus | Hom kev siv | Piv txwv |
|---|---|---|---|
| LF RFID daim ntawv pov thawj | 125-134 kHz | Access tswj, tsiaj | EM4100 FOB, TK4100 |
| HF RFID / NFC | 13.56 MHz | Kev tswj kev nkag mus, kev thauj mus los, kev them nyiaj | MIFARE Classic, NTAG213, NFC-enabled fobs |
| UHF RFID nyeem ntawv | 860–960 MHz | Cov ntaub ntawv, logistics | EPC Gen2 fobs |
Yuav qhia li cas:
Yog tias koj fob ua haujlwm nrog smartphones ntawm NFC apps, nws yogHF/NFC.
Yog tias nws tsis sib txuas lus nrog cov xov tooj tab sis ua haujlwm nrog cov neeg nyeem ntawv laus dua, nws yuav yogLF lossis UHF RFID.
2. Sim Scan nrog lub smartphone
NFC{0}}cov xov tooj tau qhib(feem ntau niaj hnub iPhones thiab Android xov tooj) nyeem tauNFC/HF fobs.
Download tau dawbNFC nyeem ntawv app:
Yog tias lub app kuaj pom tus fob, nws yogNFC / HF RFID (13.56 MHz)
Yog tias lub app tsis tuaj yeem ntes ib yam dab tsi, nws yuav zoo liLF lossis UHF RFID(tsis yog -NFC).
⚠️ LF thiab UHF fobstsis tuaj yeem nyeem los ntawm smartphones.
3. Saib ntawm Fob lossis Ntim
Qee cov fobs muajchip markings lossis qauv tooj:
EM4100 / TK4100 → LF RFID
MIFARE, NTAG, DESFire → HF/NFC RFID
Qee zaum, covntim hais txog "NFC-enabled"los yog qhov zaus (13.56 MHz).
4. Saib Kev Nyeem Ntawv Sib Raug Zoo
Yog tus fob ua haujlwm nrogtxheem qhov rooj los yog gym nyeem ntawvuas tsis hais NFC, nws yuav yogLF.
Yog nws ua haujlwm nrogsmartphone-raws li systems lossis them nyiaj terminals, yogHF/NFC.
5. Siv RFID nyeem ntawv tshwj xeeb
Rau qhov tseeb, antau- zaus RFID nyeem ntawvtuaj yeem ntes tau:
LF 125 kHz
HF / NFC 13.56 MHz
UHF 860-960 MHz
Qhov no yog qhov tseeb tshaj plaws los txheeb xyuas qhov zaus thiab hom koj fob.
✅ Txoj cai ceev ntawm tus ntiv tes xoo
Ua haujlwm nrog xov tooj / NFC app → NFC (HF RFID)
Ua haujlwm tsuas yog nrog kev nyeem ntawv ib txwm siv → LF lossis UHF RFID
Me me keychain fobs nrog hlau txheej → feem ntau LF
Yas keychain fobs nrog logos / luam ntawv → feem ntau HF / NFC
