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

Kukula kwakukulu kwa makadi a RFID kumadziwika kuti "standard credit card" size, yotchedwa ID-1 kapena CR80, ndipo kwalembedwa ndi International Standards Organisation mu chikalata cha 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″) ngodya zozungulira. Kutengera ndi njira yopangira ndi zosowa za makasitomala, makulidwe a makadi a RFID amayambira pa 0.84mm-1mm.

Masayizi apadera amapezekanso malinga ndi zosowa za makasitomala.

Kodi Khadi la RFID Limagwira Ntchito Bwanji?

Mwachidule, khadi lililonse la RFID lili ndi antenna yolumikizidwa ku RFID IC, kotero imatha kusunga ndikutumiza deta kudzera mu mafunde a wailesi. Makhadi a RFID nthawi zambiri amagwiritsa ntchito ukadaulo wa RFID wosagwiritsa ntchito ndipo safuna magetsi amkati. Makhadi a RFID amagwira ntchito ndi mphamvu yamagetsi yolandirira yomwe imaperekedwa ndi owerenga a RFID.

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

Khadi la RFID locheperako la 125KHz, mtunda wowerengera ndi 1-2cm.

Khadi la RFID la pafupipafupi kwambiri la 13.56MHz, mtunda wowerengera mpaka 10cm.

Khadi la 860-960MHz UHF RFID, mtunda wowerengera ndi mamita 1-20.

Tikhozanso kuphatikiza ma frequency awiri kapena atatu osiyanasiyana kukhala khadi limodzi la RFID.

Khalani omasuka kulumikizana nafe kuti mupeze zitsanzo ZAULERE zoyesera RFID yanu.
