Yog tias lub cim npe me dua ntawm lub xov tooj tus kais hauv cheeb tsam, ntxiv lub cim NFC luam tawm kom cov neeg siv paub qhov twg mus kais. Saib pebNFC daim ntawv qhia qhov loj merau kev puas tsuaj tag nrho.

Cov npuas npuas tuab puas tuaj yeem hloov qhov kev tiv thaiv- hlau tag?

Qee lub sij hawm tuab tsis yog-metallic spacer cia tus qauv cim ua haujlwm los ntawm kev tuav nws deb ntawm cov hlau, tab sis qhov sib txawv yuav tsum loj, qhov tshwm sim yog loj, thiab kev ntseeg siab tsis sib haum. Ib qho ferrite-rov qab los tiv thaiv- hlau tag yog nyias dua thiab muaj kev vam khom ntau dua, tshwj xeeb tshaj yog rau kev tsim khoom.

Puas tuaj yeem tiv thaiv -hlau NFC cov cim luam tawm nrog lub logo lossis tus lej cim?

Yog lawm. Cov txheej txheej saum npoo tuaj yeem nqa tag nrho - xim kos duab, NFC lub cim, thiab cov ntaub ntawv sib txawv xws li cov lej lej. Rau traceability, nug tus neeg muag khoom kom phim txhua daim ntawv luam tawm mus rau nws qhov URL encoded ua ntej tsim khoom.

Yuav ua li cas tiv thaiv -hlau NFC tags txawv ntawm UHF anti-hlau RFID cim npe?

Anti-hlau NFC tags yog rau lub xov tooj ze ze ntawm 13.56 MHz thiab nyeem ib daim ntawv ib zaug. UHF anti-hlau RFID tags ua haujlwm nyob ib ncig ntawm 900 MHz nrog tus nyeem ntawv tshwj xeeb thiab tsim los nyeem ntau cov khoom siv hlau los ntawm qhov deb, uas haum rau cov khoom loj - teev ntau dua li lub xov tooj kais.

Kuv puas tuaj yeem tau txais cov ntawv cim npe hauv ntau ua ntej lawv xa khoom?

Yog lawm. Cov cim npe tuaj yeem ua ua ntej-encoded nrog cov cim URLs lossis IDs thiab zoo- kuaj xyuas ua ntej xa khoom, uas txuag koj encoding ntawm tes. Paub meej tias cov encoding ntau thiab sib txuam sib luag thaum koj thov qhov kev tsocai.

Ntsiab Cai

• Txheem NFC cim npe tsis ua haujlwm ntawm hlau; anti-cov cim npe hlau siv txheej ferrite los ua haujlwm rau nws.
• Sib piv cov hom rau saum npoo: cov ntawv nplaum rau cov hlau tiaj tus, cov cim npe hloov tau yooj yim rau cov nkhaus, cov ntawv nruj rau sab nraum zoov.
• Match the chip to the job: NTAG for URLs, DESFire for secure access, ISO 15693 for industrial HF.
• NFC yog rau kev kaw kaw; siv UHF RFID ntev - nyeem ntawv ntau.
• Kuaj cov qauv ntawm qhov chaw tiag tiag, cov xov tooj tiag, thiab cov xwm txheej tiag tiag ua ntej xaj hauv ntim.
