Amakhadi amaningi e-RFID asasebenzisa ama-polymer epulasitiki njengezinto eziyisisekelo. I-polymer yepulasitiki esetshenziswa kakhulu yi-PVC (i-polyvinyl chloride) ngenxa yokuqina kwayo, ukuguquguquka kwayo, kanye nokuguquguquka kwayo ekwenzeni amakhadi. I-PET (i-polyethylene terephthalate) iyi-polymer yepulasitiki yesibili esetshenziswa kakhulu ekukhiqizeni amakhadi ngenxa yokuqina kwayo okuphezulu kanye nokumelana nokushisa.

Usayizi oyinhloko wamakhadi e-RFID waziwa ngokuthi usayizi “wekhadi lesikweletu elijwayelekile”, obizwa ngokuthi i-ID-1 noma i-CR80, futhi ubhalwe yi-International Standards Organisation embhalweni wemininingwane we-ISO/IEC 7810 (Amakhadi Okuhlonza – Izici Zomzimba).

I-ISO/IEC 7810 icacisa ubukhulu be-ID-1/CR80 obulingana no-85.60 x 53.98 mm (3 3⁄8″ × 2 1⁄8″), obunerediyasi engu-2.88–3.48 mm (cishe u-1⁄8″) amakhona ayindilinga. Kuye ngokuthi inqubo yokukhiqiza nezidingo zamakhasimende injani, ubukhulu bamakhadi e-RFID busukela ku-0.84mm-1mm.

Osayizi abangokwezifiso nabo bayatholakala ngokwezidingo zamakhasimende.

Isebenza Kanjani Ikhadi Le-RFID?

Kalula nje, ikhadi ngalinye le-RFID lifakwe i-antenna exhunywe kwi-RFID IC, ukuze ikwazi ukugcina nokudlulisa idatha ngamagagasi omsakazo. Amakhadi e-RFID ngokuvamile asebenzisa ubuchwepheshe be-RFID obungasebenzi futhi awadingi ukunikezwa kwamandla kwangaphakathi. Amakhadi e-RFID asebenza ngamandla kagesi kagesi atholakele akhishwa abafundi be-RFID.

Ngokwemvamisa ehlukene, amakhadi e-RFID ahlukaniswe ngezigaba ezine.

Ikhadi le-RFID eliyi-frequency ephansi engu-125KHz, ibanga lokufunda lingu-1-2cm.

Ikhadi le-RFID eliyi-frequency ephezulu engu-13.56MHz, ibanga lokufunda lifinyelela ku-10cm.

Ikhadi le-RFID le-860-960MHz UHF, ibanga lokufunda liyi-1-20 amamitha.

Singahlanganisa futhi amaza amabili noma amathathu ahlukene abe ikhadi elilodwa le-RFID.

Zizwe ukhululekile ukuxhumana nathi futhi uthole isampula yamahhala yokuhlolwa kwe-RFID yakho.
