Kodi RFID Smart Card ndi chiyani?

 

 

Kumvetsetsa momwe khadi lanzeru la RFID limagwirira ntchito ndikofunikira chifukwa limatsimikizira mwachindunji mtundu wamakhadi omwe akugwirizana ndi polojekiti yomwe wapatsidwa.

 

Mukabweretsa khadi mkati mwa ma awowerenga wogwirizana, mlongoti wa owerenga umatulutsa siginecha ya wailesi yosinthidwa pafupipafupi. Chizindikiro chimenecho chimagwira ntchito ziwiri nthawi imodzi: chimapereka mphamvu yogwiritsira ntchito chip cha khadi (popeza makhadi anzeru a RFID alibe batire yamkati), ndipo imayambitsa ndondomeko yosinthira deta yofotokozedwa ndi miyezo monga ISO/IEC 14443 kapena ISO/IEC 15693 (ISO).

 

Chip imayankha posintha gawo la owerenga, njira yotchedwakusinthasintha kwa katundu, kuyika deta yake yosungidwa mu chizindikiro chobwerera. Owerenga amasankha yankho ili, ndikulitsimikizira motsutsana ndi njira yake yopezera mwayi kapena njira yolipira, ndikumaliza ntchitoyo. Kuzungulira konseko kumachitika popanda wogwiritsa ntchito kuyika khadiyo bwino lomwe, ndichifukwa chake makadi osalumikizana nawo nthawi zambiri amachotsa zizindikiro za barcode ndi mizere ya maginito pamalo okwera-odutsa monga masiteshoni a metro ndi malo ochezera amakampani.

 

 

Si makadi onse anzeru a RFID omwe amatha kusinthana. Chinthu chimodzi chofunikira kwambiri chaukadaulo ndipafupipafupi ntchito, chifukwa imatsimikizira kuchuluka kwa kuwerenga, liwiro la data, kuthekera kwachitetezo, komanso, mozama, omwe owerenga khadi adzagwira nawo ntchito.
