Ko te nuinga o ngā kāri RFID kei te whakamahi tonu i ngā pūmua kirihou hei rauemi turanga. Ko te pūmua kirihou e whakamahia whānuitia ana ko te PVC (polyvinyl chloride) nā te mea he pakari, he ngāwari, he maha hoki ngā whakamahinga mō te hanga kāri. Ko te PET (polyethylene terephthalate) te tuarua o ngā pūmua kirihou e whakamahia whānuitia ana i roto i te hanga kāri nā te mea he roa te pakari me te ātete ki te wera.

Ko te rahi matua o ngā kāri RFID e mōhiotia ana ko te rahi "kāri nama paerewa", e kiia ana ko ID-1, ko CR80 rānei, ā, kua whakarārangihia e te International Standards Organization i roto i te tuhinga whakatakotoranga ISO/IEC 7810 (Identification Cards – Physical Characteristics).

E tohu ana te ISO/IEC 7810 i ngā āhuatanga ID-1/CR80 he rite ki te 85.60 x 53.98 mm (3 3⁄8″ × 2 1⁄8″), me te radius o te 2.88–3.48 mm (tata ki te 1⁄8″) ngā kokonga porowhita. I runga i te tukanga whakaputa me ngā hiahia o te kiritaki, ko te matotoru o ngā kāri RFID kei waenga i te 0.84mm-1mm.

Kei te wātea hoki ngā rahi ritenga kia rite ki ngā hiahia o te kiritaki.

Me pēhea te mahi a te kāri RFID?

He māmā noa iho, kei roto i ia kāri RFID he pūihi e hono ana ki te IC RFID, kia taea ai te penapena me te tuku raraunga mā roto i ngā ngaru reo irirangi. Ko te tikanga, ka whakamahia e ngā kāri RFID te hangarau RFID kore mahi, ā, kāore e hiahiatia he pūtake hiko ā-roto. Ka mahi ngā kāri RFID mā te whiwhi i te kaha hikohiko e tukuna ana e ngā kaipānui RFID.

E ai ki ngā auau rerekē, e whā ngā kāwai o ngā kāri RFID.

Kāri RFID 125KHz auau iti, tawhiti pānui 1-2cm.

Kāri RFID auau teitei 13.56MHz, te tawhiti pānui tae atu ki te 10cm.

Kāri RFID UHF 860-960MHz, tawhiti pānui 1-20 mita.

Ka taea hoki e tātou te whakakotahi i ngā auautanga rerekē e rua, e toru rānei ki roto i te kāri RFID kotahi.
