Ukuqonda umahluko phakathi kweRFID kunye neNFC

Kwimeko yetekhnoloji yanamhlanje ekhawulezayo, i-RFID (iRadio Frequency Identification) kunye ne-NFC (uNxibelelwano olukufutshane neField) ziye zavela njengeetekhnoloji ezimbini ezibalulekileyo zonxibelelwano olungenazingcingo. Nangona zabelana ngokufana okuthile, zahlukile kakhulu ngokwemisebenzi, uluhlu lonxibelelwano, kunye neemeko zesicelo. Eli nqaku lijolise ekucaciseni la mahluko kunye nokuhlola usetyenziso olwahlukeneyo lwetekhnoloji nganye.

Yintoni i-RFID?

I-RFID yiteknoloji esebenzisa amaza erediyo ukuchonga nokulandelela izinto. Iqulathe izinto ezintathu eziphambili: Iithegi zeRFID, Abafundi beRFID, kunye nenkqubo yasemva. Ithegi ye-Rfids, enokuba yi-passive (eqhutywa yisignali yomfundi) okanye esebenzayo (exhotyiswe ngebhetri), iqulethe i-microchip kunye ne-antenna. Xa umfundi we-RFID ekhupha isignali yerediyo, iyenza isebenze ithegi, ivumele ukuba idlulisele idatha kumfundi.

Ukusetyenziswa kweRFID:

Ulawulo lweCandelo loNikezelo: I-RFID isetyenziswa kakhulu kwi-logistics ukulandelela uluhlu lwezinto ezisetyenzisiweyo kunye nokulawula ikhonkco loNikezelo ngokufanelekileyo. Ivumela amashishini ukuba ajonge ukuhamba kweempahla ngexesha langempela, ukunciphisa ilahleko kunye nokuphucula ukusebenza kakuhle.

Ukulandelela Iimpahla: Iinkampani zisebenzisa i-RFID ukugcina umkhondo weempahla ezixabisekileyo, ezifana nezixhobo kunye nezixhobo. Le teknoloji inceda ekuthinteleni ukulahleka nokubiwa, iqinisekisa ukuba iimpahla zihlala zibalwa ngamaxesha onke.

Ulawulo Lokufikelela: I-RFID isetyenziswa kakhulu kwiinkqubo zokhuseleko zokulawula ukufikelela. Amakhadi okanye iithegi ezisebenzisa i-RFID zinokuvumela okanye zithintele ukufikelela kwiindawo ezikhuselekileyo, nto leyo ephucula ukhuseleko kwiindawo zokusebenza nakwizibonelelo.

Ukuthengisa: Kwiindawo zokuthengisa, iteknoloji ye-RFID isetyenziselwa ulawulo lwezinto ezisetyenzisiweyo kunye nokuthintela ilahleko. Ivumela abathengisi ukuba baskene izinto ngokukhawuleza xa behlawula kwaye bajonge amanqanaba esitokhwe ngexesha langempela.

Yintoni i-NFC?

I-NFC liqela letekhnoloji ye-RFID evumela unxibelelwano olufutshane phakathi kwezixhobo. Ngokwesiqhelo isebenza ngaphakathi koluhlu lweesentimitha ezi-4 okanye ngaphantsi, nto leyo eyenza ukuba ilungele ukuthengiselana ngokukhuselekileyo. Izixhobo ze-NFC zinokuba zisebenza (njengee-smartphone) okanye zingasebenzi (njengeethegi ze-NFC). Le teknoloji ivumela unxibelelwano oluhamba macala omabini, ivumela izixhobo ukuba zitshintshiselane ngedatha ngaphandle kokuphazamiseka.

Usetyenziso lwe-NFC:

Iintlawulo zeSelfowuni: Enye yezona zicelo zidumileyo ze-NFC zikwiinkqubo zokuhlawula zeselfowuni. Abasebenzisi banokwenza iintengiselwano ezikhuselekileyo ngokucofa nje ii-smartphones zabo kwi-terminal yokuhlawula enikwe amandla yi-NFC, okwenza inkqubo yokuhlawula ikhawuleze kwaye ibe lula.

Ukuthengisa Amathikithi Akrelekrele: I-NFC isetyenziswa ngakumbi kwiinkqubo zothutho lukawonke-wonke zokuthengisa amathikithi akrelekrele. Abakhweli banokucofa amakhadi abo okanye ii-smartphones ezisebenza nge-NFC kubafundi ukuze bafikelele koololiwe, iibhasi, kunye nezinye iindlela zothutho, nto leyo eyenza kube lula ukuba abantu bahambe.

Ukudityaniswa kwezixhobo: I-NFC yenza lula inkqubo yokudityaniswa kwezixhobo, ezifana nezithethi zeBluetooth okanye ii-headphone. Abasebenzisi banokuqhagamshela izixhobo ngokuzisondeza, besusa isidingo seenkqubo zokuseta ezintsonkothileyo.

Amakhadi eShishini eDijithali: Itekhnoloji ye-NFC ivumela abasebenzisi ukuba babelane ngolwazi loqhagamshelwano ngokulula. Ngokucofa ikhadi leshishini elisebenza nge-NFC kwifowuni ephathwayo, abasebenzisi banokudlulisela iinkcukacha zabo ngoko nangoko, nto leyo eyenza uthungelwano lube lusebenza ngakumbi.

Umahluko oPhambili

1. Uluhlu

Uninzi lwezixhobo zeRFID ezikumgangatho oqhelekileyo zinomgama olinganiselweyo ukusuka kwiimitha ezi-3 ukuya kwezi-5. Ngokwahlukileyo koko, azinyanzelekanga ukuba ithegi ibonakale ngqo kumfundi. Ngokwahlukileyo koko, izixhobo ze-NFC zinomgama omfutshane kakhulu ukusuka kwi-1 ukuya kwi-10 centimeters kwaye zifuna ukuba ithegi ibe kumgca othe ngqo wokubona kwe-initiator.

2. Uhlobo loNxibelelwano

Ukuchongwa kwerediyo rhoqo (RFID) kwenza kube lula unxibelelwano oluya kwicala elinye kuphela, apho umfundi efumana idatha evela kwithegi ngaphandle kokuyiphendula. Ngokwahlukileyo koko, izixhobo ze-NFC zinobuchule bokusebenza njengabafundi kunye neethegi ngokutshintsha iindima zazo, zivumela unxibelelwano oluya kwicala elinye kunye nokutshintshiselana ngolwazi.

3. Isantya sokuDlulisela idatha

Unxibelelwano olukufutshane (i-NFC) lusebenza ngesantya sokudlulisa idatha esicothayo, esingadluli kwi-424 kbit/s. Izixhobo ze-RFID, kwelinye icala, zihlala zikhawuleza. Ukongeza, abafundi be-RFID banokukwazi ukuskena iithegi ezininzi ngaxeshanye, ngokungafaniyo nabafundi be-NFC.

4. Iintlobo zeDatha

Iithegi ze-RFID zikhawulelwe ekugcineni ulwazi olulula lwe-ID. Ngokwahlukileyo koko, iithegi ze-NFC zinokuthwala iintlobo ezahlukeneyo zedatha kwaye zibe namandla amakhulu ememori, nto leyo ezenza zibe zilungele iintengiselwano zentlawulo.

Isiphelo

Ngamafutshane, i-RFID kunye ne-NFC ziiteknoloji ezimbini ezahlukeneyo ezisebenza ngeenjongo ezahlukeneyo kwihlabathi lanamhlanje. I-RFID igqwesile kwizicelo ezifuna ukuchongwa kunye nokulandelela umgama omde, ngelixa i-NFC ikhanya kwiimeko ezifuna unxibelelwano olukhuselekileyo nolufutshane. Njengoko iteknoloji iqhubeka nokukhula, zombini i-RFID kunye ne-NFC ziya kudlala indima ebalulekileyo ekwandiseni ukusebenza kakuhle kunye nokulula kuzo zonke izimboni ezahlukeneyo. Ukuqonda umahluko kunye nezicelo zazo kunokunceda amashishini kunye nabathengi ukuba benze izigqibo ezinolwazi malunga nokuba loluphi ubuchwephesha olufanele iimfuno zabo.
