Ukuqonda Umehluko Phakathi Kwe-RFID Ne-NFC
Esimweni sobuchwepheshe banamuhla esisheshayo, i-RFID (Radio Frequency Identification) kanye ne-NFC (Near Field Communication) ziye zavela njengobuchwepheshe obubili obubalulekile bokuxhumana obungenantambo. Nakuba zabelana ngokufana okuthile, zihluka kakhulu ngokusebenza, ububanzi bokuxhumana, kanye nezimo zohlelo lokusebenza. Lesi sihloko sihlose ukucacisa lo mehluko nokuhlola izinhlelo zokusebenza ezahlukahlukene zobuchwepheshe ngabunye.
Kuyini i-RFID?
I-RFID ubuchwepheshe obusebenzisa amaza omsakazo ukuhlonza nokulandelela izinto. Yakhiwa izingxenye ezintathu eziyinhloko: Amathegi e-RFID, Abafundi be-RFID, kanye nesistimu yangemuva. Ithegi ye-Rfids, okungaba yi-passive (enikwe amandla yisignali yomfundi) noma esebenzayo (efakwe ibhethri), iqukethe i-microchip kanye ne-antenna. Uma umfundi we-RFID ekhipha isignali yomsakazo, ivula ithegi, iyivumele ukuthi idlulisele idatha emuva kumfundi.
Ukusetshenziswa kwe-RFID:
Ukuphathwa Kwe-Supply Chain: I-RFID isetshenziswa kabanzi kwezokuthutha ukulandelela isitokwe kanye nokuphatha i-supply chain ngempumelelo. Ivumela amabhizinisi ukuqapha ukuhamba kwezimpahla ngesikhathi sangempela, ukunciphisa ukulahlekelwa kanye nokuthuthukisa ukusebenza kahle.
Ukulandelela Impahla: Izinkampani zisebenzisa i-RFID ukulandelela izimpahla ezibalulekile, njengemishini namathuluzi. Lobu buchwepheshe buyasiza ekuvimbeleni ukulahleka nokwebiwa, ukuqinisekisa ukuthi izimpahla ziyabalwa ngaso sonke isikhathi.
Ukulawula Ukufinyelela: I-RFID ivame ukusetshenziswa ezinhlelweni zokuphepha zokulawula ukufinyelela. Amakhadi noma amathegi asebenzisa i-RFID anganikeza noma anciphise ukufinyelela ezindaweni eziphephile, okuthuthukisa ukuphepha ezindaweni zokusebenza nasezikhungweni.
Ukuthengisa: Ezindaweni zokuthengisa, ubuchwepheshe be-RFID busetshenziselwa ukuphathwa kwempahla kanye nokuvimbela ukulahleka. Buvumela abathengisi ukuthi baskene izinto ngokushesha lapho bekhokha futhi baqaphe amazinga esitokwe ngesikhathi sangempela.
Kuyini i-NFC?
I-NFC iyisethi encane yobuchwepheshe be-RFID evumela ukuxhumana okufushane phakathi kwamadivayisi. Ngokuvamile isebenza ngaphakathi kwebanga elingamasentimitha angu-4 noma ngaphansi, okwenza kube kuhle kakhulu ekuthengiselaneni okuphephile. Amadivayisi e-NFC angaba asebenzayo (njengama-smartphone) noma angasebenzi (njengamathegi e-NFC). Ubuchwepheshe buvumela ukuxhumana okubili, okuvumela amadivayisi ukushintshanisa idatha kalula.
Izicelo ze-NFC:
Izinkokhelo Zeselula: Enye yezinhlelo zokusebenza ezidumile ze-NFC isezinhlelweni zokukhokha zeselula. Abasebenzisi bangenza ukuthengiselana okuphephile ngokuthepha nje ama-smartphone abo eduze kwetheminali yokukhokha enikwe amandla yi-NFC, okwenza inqubo yokukhokha isheshe futhi ibe lula.
Ukuthengisa Amathikithi Ahlakaniphile: I-NFC isetshenziswa kakhulu ezinhlelweni zokuhamba zomphakathi zokuthengisa amathikithi ahlakaniphile. Abagibeli bangathinta amakhadi abo noma ama-smartphone asebenzisa i-NFC kubafundi ukuze bafinyelele izitimela, amabhasi, nezinye izinhlobo zokuhamba, okwenza kube lula ukuhamba.
Ukubhanqa Amadivayisi: I-NFC yenza inqubo yokubhanqa amadivayisi, njengezipikha ze-Bluetooth noma ama-headphone ibe lula. Abasebenzisi bangaxhuma amadivayisi ngokuwasondeza ndawonye, kususwe isidingo sezinqubo zokusetha eziyinkimbinkimbi.
Amakhadi Ebhizinisi Edijithali: Ubuchwepheshe be-NFC buvumela abasebenzisi ukuthi babelane ngolwazi lokuxhumana kalula. Ngokuthinta ikhadi lebhizinisi elisebenzisa i-NFC ngokumelene ne-smartphone, abasebenzisi bangadlulisela imininingwane yabo ngokushesha, okwenza ukuxhumana kube ngcono kakhulu.
Umehluko Oyinhloko
1. Ububanzi
Amadivayisi amaningi e-RFID asezingeni elivamile anobubanzi obulinganiselwe bamamitha amathathu kuya kwangu-5. Ngokuphambene nalokho, awadingi ukuthi ithegi ibonakale ngqo kumfundi. Ngokuphambene nalokho, amadivayisi e-NFC anobubanzi obufushane kakhulu obungamasentimitha angu-1 kuya kwangu-10 futhi adinga ukuthi ithegi ibe seduze ngqo nomuntu oqalayo.
2. Uhlobo Lokuxhumana
Ukuhlonza imvamisa yomsakazo (RFID) kwenza kube lula ukuxhumana ngendlela eyodwa kuphela, lapho umfundi ethola khona idatha evela kuthegi ngaphandle kokuyiphendula. Ngokuphambene nalokho, amadivayisi e-NFC anokuguquguquka kokusebenza njengabafundi kanye namathegi ngokushintsha izindima zawo, okwenza kube lula ukuxhumana ngezindlela ezimbili kanye nokushintshana kolwazi.
3. Isivinini Sokudlulisa Idatha
Ukuxhumana kwe-Near field (NFC) kusebenza ngesivinini sokudlulisa idatha esihamba kancane, esingadluli ku-424 kbit/s. Amadivayisi e-RFID, ngakolunye uhlangothi, ngokuvamile ashesha. Ngaphezu kwalokho, abafundi be-RFID banekhono lokuskena amathegi amaningi ngesikhathi esisodwa, ngokungafani nabafundi be-NFC.
4. Izinhlobo Zedatha
Amathegi e-RFID anqunyelwe ukugcina ulwazi olulula lwe-ID. Ngokuphambene nalokho, amathegi e-NFC angamukela izinhlobo ezahlukene zedatha futhi abe namandla amakhulu ememori, okwenza afaneleke kakhulu ekukhokheni.
Isiphetho
Ngamafuphi, i-RFID ne-NFC ubuchwepheshe obubili obuhlukile obufeza izinjongo ezahlukene ezweni lanamuhla. I-RFID ihamba phambili ezinhlelweni zokusebenza ezidinga ukuhlonza nokulandelela ibanga elide, kuyilapho i-NFC ikhanya ezimweni ezidinga ukuxhumana okuphephile, okufushane. Njengoba ubuchwepheshe buqhubeka nokukhula, kokubili i-RFID ne-NFC zizodlala indima ebaluleke kakhulu ekuthuthukiseni ukusebenza kahle kanye nokulula kuzo zonke izimboni ezahlukene. Ukuqonda umehluko wazo kanye nezinhlelo zokusebenza kungasiza amabhizinisi nabathengi ukuthi benze izinqumo ezinolwazi mayelana nokuthi yibuphi ubuchwepheshe obufanela kangcono izidingo zabo.
