NFC anti-hlau tag yog ua los ntawm daim ntawv nplaum lossis daim npav PVC nrog ib txheej ntawm cov khoom nqus dej, uas tuaj yeem ua tiav cov nyhuv ntawm kev cuam tshuam hlau. Daim ntawv lo tuaj yeem nyeem thiab sau rau ntawm qhov chaw ntawm cov hlau. PVC nrog daim ntawv lo tiv thaiv hlau tuaj yeem tiv thaiv dej, kua qaub, alkali thiab kev sib tsoo, thiab tuaj yeem siv sab nraum zoov.
Daim ntawv cim NFC anti hlau uas tsim los ntawm MINA tuaj yeem ua nrog plaub pawg NFC hauv qab no:

Hom NFC anti-metal tag thawj yog raws li 14443a protocol. Qhov tsawg kawg nkaus ntawm lub cim xeeb yog 96 bytes, uas tuaj yeem nthuav dav dynamically. Yog tias cov cim npe tsuas yog muaj kev nyeem-sau cia yooj yim, xws li kev siv cov haujlwm yooj yim ntse poster, cov cim npe no muaj tag nrho. Hom cim npe no feem ntau yog siv los nyeem cov ntaub ntawv thiab muaj qhov zoo ntawm kev ua haujlwm yooj yim thiab tus nqi qis.

Hom thib ob ntawm NFC anti-metal label kuj yog raws li 14443a protocol, tab sis tsuas yog txhawb nqa daim npav los ntawm Phlips.

Hom thib peb NFC hlau tiv taus daim ntawv lo yog hom thev naus laus zis fecila uas muab los ntawm Sony xwb.

Hom plaub NFC anti-hlau tag yog nrog 14443A/B protocol. Hom tag no yog ib feem ntawm Intelligent Tag, tau txais cov lus qhia ntawm Application Protocol Data Unit (APDU), muaj chaw cia khoom loj, ua tiav qee qhov authentication lossis security algorithm, thiab siv tau los ua kom muaj kev sib cuam tshuam ntse thiab kev ua haujlwm ntawm dual interface label. Hom daim ntawv no muaj ntau yam kev siv thiab tuaj yeem hloov kho rau kev tshawb fawb thiab kev txhim kho tas mus li yav tom ntej.
