Nrog cov koob nrov ntawm cov xov tooj ntse, kev siv tus nqi ntawm QR code tiv thaiv cov ntawv luam tawm tau maj mam nce, tab sis qee cov khoom me me dhau los nqa QR code tiv thaiv cov ntawv luam tawm. Lub sijhawm no, NFC cov ntawv ntse yog xav tau los pab. Yog li, dab tsi yog NFC daim ntawv lo tiv thaiv cuav?
NFC hais txog kev sib txuas lus nyob ze, uas muaj ntau daim ntawv thov, suav nrog kev tiv thaiv kev ua txhaum cai, uas yog, hu ua hluav taws xob tiv thaiv daim ntawv lo. NFC tiv thaiv kev ua txhaum cai siv NFC cim npe los tiv thaiv cov khoom cuav. Cov neeg tsim khoom sau cov ntaub ntawv khoom lag luam encrypted hauv NFC cov cim hluav taws xob thiab txuas cov cim hluav taws xob rau cov khoom ntim. Cov neeg siv khoom tau nyeem cov cim hluav taws xob los ntawm daim ntawv thov App ntawm NFC lub xov tooj ntawm tes, txiav txim siab cov ntaub ntawv tag, thiab txiav txim qhov tseeb ntawm cov khoom.
Txhua NFC hluav taws xob tag muaj cov lej hluav taws xob tshwj xeeb. Cov ntaub ntawv encryption tag yog tsim los ntawm cov chaw tsim khoom siv nws daim ntawv pov thawj digital tus yuam sij rau encrypt cov khoom thiab cov ntaub ntawv tag, kom txhua yam khoom muaj qhov tshwj xeeb "ID card", uas tsis tuaj yeem theej lossis forged. NFC cov cim npe hluav taws xob tsuas yog xav tau thaj chaw me me los nqa ntau cov ntaub ntawv, rhuav tshem thaj chaw txwv, thiab tseem tuaj yeem txhawb nqa cov tuam txhab lag luam.
Yog li, dab tsi yog cov txheej txheem tshwj xeeb thaum cov tuam txhab thov rau NFC cov ntawv pov thawj pov thawj?
