Makhadi ambiri a RFID amagwiritsabe ntchito ma polima apulasitiki ngati maziko.Polima wapulasitiki omwe amagwiritsidwa ntchito kwambiri ndi PVC (polyvinyl chloride) chifukwa cha kukhazikika kwake, kusinthasintha, komanso kusinthasintha popanga makhadi.PET (polyethylene terephthalate) ndi yachiwiri yomwe imagwiritsidwa ntchito polima pulasitiki popanga makadi chifukwa cha kulimba kwake komanso kukana kutentha.

Kukula kwakukulu kwa makhadi a RFID kumadziwika kuti "standard credit card" size, yodziwika ID-1 kapena CR80, ndipo amalembedwa ndi International Standards Organisation mu chikalata chofotokozera ISO/IEC 7810 (Identification Cards - Physical Characteristics).

ISO/IEC 7810 imatchula miyeso ya ID-1/CR80 yofanana ndi 85.60 x 53.98 mm (3 3⁄8″ × 2 1⁄8″ ), yokhala ndi utali wa 2.88–3.48 mm (pafupifupi 1⁄8″)Kutengera ndi kupanga ndi zosowa za kasitomala, makulidwe a makhadi a RFID amachokera ku 0.84mm-1mm.

Makulidwe achikhalidwe amapezekanso malinga ndi zosowa za kasitomala.

Kodi RFID Card Imagwira Ntchito Motani?

Mwachidule, khadi lililonse la RFID limaphatikizidwa ndi mlongoti wolumikizidwa ku RFID IC, kotero imatha kusunga ndikutumiza deta kudzera pa mafunde a wailesi.Makhadi a RFID nthawi zambiri amagwiritsa ntchito ukadaulo wa RFID ndipo safuna mphamvu yamkati.Makhadi a RFID amagwira ntchito polandira mphamvu yamagetsi yotulutsidwa ndi owerenga RFID.

Malinga ndi ma frequency osiyanasiyana, makhadi a RFID amagawidwa m'magulu anayi.

Otsika pafupipafupi 125KHz RFID khadi, kuwerenga mtunda 1-2cm.

Mkulu pafupipafupi 13.56MHz RFID khadi, kuwerenga mtunda mpaka 10cm.

860-960MHz UHF RFID khadi, kuwerenga mtunda 1-20 mamita.

Titha kuphatikizanso ma frequency awiri kapena atatu kukhala khadi limodzi la RFID.

Khalani omasuka kulumikizana nafe ndikupeza zitsanzo ZAULERE zoyesa RFID yanu.
