A: Ib qho URL feem ntau zoo dua vim tias koj tuaj yeem hloov kho nplooj ntawv tsaws tom qab. Lub vCard khaws cia ncaj qha rau ntawm daim ntawv tuaj yeem ua haujlwm offline, tab sis nws siv ntau lub cim xeeb thiab dhau los ua dhau los thaum cov ntaub ntawv tiv tauj hloov pauv.
Q: Puas NFC Tags ua haujlwm los ntawm kev ntim khoom?
A: Feem ntau yog yog hais tias lub ntim yog ntawv, cardboard, yas, los yog iav thiab tag antennas loj txaus. Ntawv ci, metalized zaj duab xis, kua- ntim ntim, thiab cov thawv hlau yuav tsum tau kuaj tshwj xeeb thiab feem ntau xav tau kev tiv thaiv- hlau lossis kev cai kav hlau txais xov.
Yog li dab tsi yog NFC tag
Passive RF ntaus ntawv. Tsim los ntawm electromagnetic coupling ntawm 13.56 MHz. Khaws cov lus NDEF me me lossis cov ntaub ntawv thov kev ruaj ntseg. Nyeem tau los ntawm NFC-enabled smartphones thiab tshaj nyeem ntawv. Nco tau los ntawm me me URL payloads mus rau NDEF cov ntaub ntawv loj dua nyob ntawm nti. Kev ruaj ntseg muaj los ntawm kev tiv thaiv tus password yooj yim mus rau cryptographic authentication.
Xaiv hom 2 NTAG21x rau tus nqi- cov ntawv thov siv tau yooj yim. Xaiv hom 4 ruaj ntseg cim npe thaum koj xav tau kev lees paub tiag tiag. Siv los tiv thaiv- hlau tsim thaum daim ntawv lo zaum ntawm hlau. Tus account rau cov khoom siv, kav hlau txais xov loj, nplaum, xov tooj qauv thiab tus cwj pwm nyeem ntawv ua ntej ntau lawm.
Qhov ntawd yog cov ntsiab lus uas siv tau.
