RFID tag umahluko

I-Radio frequency identification (RFID) iithegi okanye iitransponder zizixhobo ezincinci ezisebenzisa amaza erediyo anamandla aphantsi ukufumana, ukugcina nokuhambisa idatha kumfundi okufutshane. Ithegi ye-RFID iqulethe izinto eziphambili ezilandelayo: i-microchip okanye i-circuit edibeneyo (IC), i-antenna, kunye ne-substrate okanye umaleko wezinto ezikhuselayo ezigcina onke amacandelo kunye.

Kukho iintlobo ezintathu ezisisiseko zeethegi ze-RFID: i-passive, esebenzayo, i-semi-passive okanye i-battery assisted passive passive (BAP). Iithegi ze-Passive RFID azinamthombo wamandla wangaphakathi, kodwa zinikwe amandla yi-electromagnetic energy ephuma kumfundi we-RFID. Iithegi ze-RFID ezisebenzayo ziphethe i-transmitter yazo kunye nomthombo wamandla kwithegi. Iithegi ze-semi-passive okanye ibhetri encediswayo kukwenziwa (BAP) ziquka umthombo wamandla odityaniswe kuqwalaselo lwethegi yokwenziwa. Ukongezelela, iithegi ze-RFID zisebenza kwiintlobo ezintathu zefrikhwensi: I-Ultra High Frequency (UHF), i-Frequency ephezulu (HF) kunye ne-Low Frequency (LF).

Iithegi ze-RFID zinokudityaniswa kwiindawo ezahlukeneyo kwaye zifumaneka ngokubanzi kwiisayizi ezahlukeneyo kunye noyilo. Iithegi ze-RFID nazo ziza ngeendlela ezininzi, kubandakanywa kodwa kungaphelelanga ekufakweni okumanzi, iileyibhile ezomileyo, iithegi, iintambo zesandla, iithegi ezinzima, amakhadi, izincamathelisi, kunye nezacholo. Iithegi zeRFID ezinophawu ziyafumaneka kwiindawo ezininzi ezahlukeneyo kunye nokusetyenziswa,
