Ukuchongwa kweRadio Frequency (I-RFID) kunye noNxibelelwano lweNdawo ekufutshane (NFC) ngamagama angundoqo amabini ashushu, zombini ezi ziTekhnoloji zeTagging. I-NFC iphuhliswe ngesiseko se-RFID, I-NFC ayahlukanga kangako kwi-RFID ngokubaluleka, kwaye isekwe kugqithiso lomqondiso phakathi kwezinto ezimbini ezineendawo ezifanayo zejografi.
I-RFID yitekhnoloji yokuchonga engaqhagamshelwanga, yahlulwe yaba zimbini ezisebenzayo nezingazenziyo. Umgaqo ongundoqo osebenzayo kukuba umfundi we-RFID ukhupha i-radio frequency, idlula kwikhoyili yethegi ye-elektroniki, yenza umqondiso, kwaye umfundi uyalufunda ulwazi aze aluchaze, ukugqiba yonke inkqubo yokuchonga. Ngesiqhelo, iithegi ezisebenzayo (iithegi ezisebenzayo) inokuthumela imiqondiso ngokusebenzayo. Iinkqubo ze-RFID ziqulunqwe ikakhulu ngabafundi kunye neetransponders.
I-NFC yitekhnoloji esetyenziswa kakhulu kwiiselfowuni kwiminyaka yakutshanje, ubukhulu becala xa izixhobo ezibini ze-NFC zikufuphi enye kwenye kumgama okufutshane ngokufanelekileyo, banokutshintshiselana ngolwazi kunye nomnye kwaye bagqibe ukuthengiselana okuhambelanayo kunye neminye imisebenzi. Eyona nto inkulu ye-NFC kukudityaniswa komfundi kunye ne-transponder kwi-chip efanayo. Itekhnoloji ye-NFC yongeza umsebenzi wonxibelelwano we-point-to-point, enokuseka ngokukhawuleza iP2P (khomba-kwinqaku) unxibelelwano olungenazingcingo phakathi kwezixhobo zeBluetooth, kunye nezixhobo ze-NFC ziyafumanana kwaye ziseke unxibelelwano lonxibelelwano. Izixhobo ezibini zonxibelelwano lwe-P2P ziontanga, ngelixa izixhobo ezibini zonxibelelwano lweRFID ziyinkosi-khoboka.
Ubudlelwane phakathi kwezi zibini kukuba i-NFC inokuqwalaselwa njengeseti ephantsi ye-RFID, yiyo i, I-RFID enomgama wonxibelelwano we-10cm okanye 4 i-intshi yiNFC. I-NFC ilinganiselwe kuphela kwibhendi ye-13.56MHz! Ibhendi yefrikhwensi yeRFID ine frequency ephantsi (125KHz ukuya kwi-135KHz), amaza aphezulu (13.56MHz) kunye ne-ultra-high frequency (860MHz ukuba 960MHz). Lo mahluko ikakhulu ngenxa yokuba kwezinye izicelo eyenzelwe iintlawulo zemali kunye namakhadi etyala, ezinye izixhobo nazo zinokufumana ulwazi lwe-RFID yobuqu xa umgama wonxibelelwano uphantsi, kwaye kukho izinto ezingakhuselekanga. Umgama osebenzayo we-NFC umalunga ne-10cm, ngoko inokhuseleko oluphezulu. Ukuba kusetyenziswe isixhobo esikhethekileyo sokufumana umqondiso, ulwazi lweRFID lunokufundwa kumgama omde.
