I-Radio Frequency Identification (I-RFID) kanye Nokuxhumana Kwenkundla Eseduze (I-NFC) amagama angukhiye amabili ashisayo, kokubili ubuchwepheshe bokumaka. I-NFC yakhiwe ngesisekelo se-RFID, I-NFC ayihlukile kakhulu ku-RFID empeleni, futhi isekelwe ekudlulisweni kwesignali phakathi kwezinto ezimbili ezinezindawo ezifanayo.
I-RFID ubuchwepheshe bokuhlonza okungeyena othintana naye, ihlukaniswe yaba yizinto ezimbili ezisebenzayo nezingenzi lutho. Umgomo oyinhloko wokusebenza ukuthi umfundi we-RFID ukhipha amaza omsakazo, idlula ikhoyili yethegi ye-elekthronikhi, yakha isignali, futhi umfundi ufunda ulwazi futhi aluhlukanise, ukuqedela yonke inqubo yokuhlonza. Ngokuvamile, amathegi asebenzayo (amathegi asebenzayo) futhi ingathumela amasignali ngenkuthalo. Amasistimu e-RFID ikakhulukazi akhiwe abafundi nama-transponder.
I-NFC ubuchwepheshe obusetshenziswa kakhulu komakhalekhukhwini eminyakeni yamuva nje, ikakhulukazi uma amadivayisi amabili e-NFC eseduze kwelinye ebangeni eliseduze, bangashintshisana ngolwazi futhi bagcwalise ukuthengiselana okuhambisanayo neminye imisebenzi. Isici esikhulu kunazo zonke se-NFC ukuhlanganiswa komfundi kanye ne-transponder ku-chip efanayo. Ubuchwepheshe be-NFC bungeza umsebenzi wokuxhumana we-point-to-point, engasungula ngokushesha i-P2P (iphuzu-kuya-iphuzu) ukuxhumana okungenantambo phakathi kwamadivaysi e-Bluetooth, kanye namadivayisi e-NFC ayatholana futhi asungule ukuxhumana kokuxhumana. Amadivayisi amabili okuxhumana kwe-P2P awontanga kuya kontanga, kuyilapho izisetshenziswa ezimbili zokuxhumana ze-RFID ziyi-master-slave.
Ubudlelwano phakathi kwalokhu kokubili ukuthi i-NFC ingathathwa njengesethi engaphansi ye-RFID, leyo, I-RFID enebanga lokuxhumana elingu-10cm noma 4 amayintshi yi-NFC. I-NFC ikhawulelwe kuphela kubhendi engu-13.56MHz! Ibhendi yefrikhwensi ye-RFID inefrikhwensi ephansi (125KHz ukuya ku-135KHz), imvamisa ephezulu (13.56MHz) kanye ne-ultra-high frequency (860MHz ukuze 960MHz). Lo mehluko ubangelwa ikakhulukazi ukuthi kwezinye izinhlelo zokusebenza eziklanyelwe izinkokhelo zemali namakhadi esikweletu, amanye amadivaysi angathola ulwazi lomuntu siqu lwe-RFID uma ibanga lokuxhumana liphansi, futhi kunezici ezingavikelekile. Ibanga elisebenzayo le-NFC licishe libe ngu-10cm, ngakho inokuphepha okuphezulu. Uma kusetshenziswa okokusebenza okukhethekile kokutholwa kwesignali, ulwazi lwe-RFID lungafundwa kude kakhulu.
