Feem ntau RFID daim npav tseem siv cov yas polymers ua cov khoom siv hauv paus.Qhov feem ntau siv cov yas polymer yog PVC (polyvinyl chloride) vim nws cov durability, yooj, thiab versatility rau daim npav.PET (polyethylene terephthalate) yog qhov thib ob feem ntau siv cov yas polymer hauv daim npav ntau lawm vim nws muaj zog thiab ua haujlwm kub.

Qhov loj ntawm RFID daim npav yog lub npe hu ua "tus qauv credit card" loj, tsim ID-1 lossis CR80, thiab raug teeb tsa los ntawm International Standards Organization nyob rau hauv cov ntaub ntawv specification ISO/IEC 7810 (Identification Cards – Physical Characteristics).

ISO / IEC 7810 qhia ID-1 / CR80 qhov ntev sib npaug li 85.60 x 53.98 mm (3 3⁄8 ″ × 2 1⁄8 ″), nrog lub vojvoog ntawm 2.88–3.48 mm (kwv yees li 1⁄8 ″) puag ncig.Nyob ntawm seb nyob ntawm cov txheej txheem tsim khoom thiab cov neeg siv khoom xav tau, lub thickness ntawm RFID phaib ranges ntawm 0.84mm-1mm.

Kev cai qhov ntau thiab tsawg kuj muaj raws li cov neeg siv khoom xav tau.

RFID Card ua haujlwm li cas?

Tsuas yog, txhua daim npav RFID yog kos nrog lub kav hlau txais xov txuas nrog RFID IC, yog li nws tuaj yeem khaws thiab xa cov ntaub ntawv los ntawm xov tooj cua tsis muaj zog.RFID phaib feem ntau siv passive RFID thev naus laus zis thiab yuav tsum tsis muaj hluav taws xob sab hauv.RFID phaib ua haujlwm los ntawm kev txais hluav taws xob hluav taws xob tawm los ntawm RFID nyeem ntawv.

Raws li ntau zaus, RFID phaib tau muab faib ua plaub pawg.

Tsawg zaus 125KHz RFID daim npav, nyeem ntawv nrug 1-2cm.

High zaus 13.56MHz RFID daim npav, nyeem ntawv nrug txog 10cm.

860-960MHz UHF RFID daim npav, nyeem ntawv nrug 1-20 meters.

Peb kuj tuaj yeem muab ob lossis peb qhov sib txawv ntau zaus rau hauv ib daim npav RFID.

Xav tias dawb hu rau peb thiab tau txais cov qauv dawb rau koj qhov kev kuaj RFID.
