Umsantsa ongundoqo wokuSebenza
Olo bhidano malunga nokuba yeyiphi itekhnoloji apho kugcinwa khona iiprojekthi, kwaye ihlala ijongana naloo mzuzu umthengisi engakwazi ukutsho ukuba bacaphula phi na.
Amaza omoya afanayo, imisebenzi eyahlukileyo kakhulu
Kwi-13.56 MHz, ithegi ye-NFC yokwenziwa kunye nethegi ye-HF RFID zisondele ngokufanayo kwidayagram yesekethe, yiyo loo nto umahluko phakathi kwe-RFID kunye ne-NFC ufiphala kwiingcaciso ezininzi. Ukwahlula okubalulekileyo kukusebenza, hayi ngokwasemzimbeni. Ukonakaliswa okunzulu kobugcisa bendlela eziprothokholi ezimbini ezihlukana ngayo kwinqanaba eliqhelekileyo, lethuI-RFID vs NFC isikhokelo sokuthelekisa iprotocoligubungela imigangatho ye-ISO, -ku{1}}indlela zontanga, kunye nenyani{2}}indlela yokuziphatha efundwayo yehlabathi icala elinye.
RFID lusapho. Idibanisa amaza aphantsi (malunga ne-125-134 kHz), i-frequency ephezulu (13.56 MHz), kunye ne-ultra{{4}i-frequency ephezulu (malunga 860-960 MHz), kwaye olo khetho lwamafrikhwensi luthatha isigqibo malunga nayo yonke into malunga noluhlu kunye nokuziphatha. Ozethu bhala{8} phezuluindlela iHF kunye ne-UHF yokufunda ahluke ngayoingena nzulu, kodwa isihloko silula: umfundi we-UHF unokutsala idatha ukusuka kwiithegi ezininzi kude ngaphandle komgca wokubona. Apha kulapho i-RFID kunye ne-NFC zihlukana khona kakhulu xa uluhlu lungena kwincoko, kuba i-NFC iphosa ngabom uluhlu. Isebenza kuphela kwiisentimitha ezimbalwa, inxibelelana ngeendlela ezimbini endaweni yenye, kwaye, ngokungafaniyo ne-RFID eninzi, ijika nayiphi na i-smartphone yanamhlanje ibe ngumfundi.
"Loo nqaku lokugqibela yinto esebenzayo. Ifowuni ifunda iithegi ze-HF kunye ne-NFC; ayikwazi ukufunda iithegi ze-125 kHz okanye ze-UHF kwaphela. Ngoko ukuqulunqwa okunyanisekileyo kwe-RFID vs NFC kulawulo lokufikelela okanye ukusebenzisana kwemveliso 'ayikho 'ehamba phambili.' 'Ngaba ufuna umntu ukuba acofe into ethile ngabom, okanye umatshini wokutshayela izinto ezininzi ngaxeshanye?'
Imigangatho engaphantsi (ISO/IEC 14443 kunye ne-15693 yamakhadi, 18092 yentanga ye-NFC-uku{4}}indlela yoontanga) ikhona ukugcina loo misebenzi mibini isebenzisana ngaphandle kokwenza ngathi ingumsebenzi ofanayo.
Uluhlu lokufunda kwi-database ayiloluhlu lokufunda kumgangatho wakho
Isikhewu ekungekho mntu usibekayo kwincwadana yile: uluhlu olufundwayo olushicilelwe kwiphepha lenkcazo yethegi yinombolo yaselabhorethri, kwaye indawo yakho yokugcina asiyoelebhu. Isinyithi, ulwelo, uluhlu lweempahla ezipakishweyo, ubushushu, kunye ne-engile yethegi ejongene ne-eriyali zonke ziya kulicutha elo nani, ngamanye amaxesha ngokumangalisayo. Okwenyani-iimeko zehlabathi zokubeka i-RFID kunye ne-NFC kumgangatho wefektri zimbi kunalo naluphi na ugcino-lwazi olubonisayo, kwaye umgama phakathi komqhubi wenqwelo-moya ococekileyo kunye nokukhutshwa okumisiweyo ngokuqhelekileyo uhlala kwezi nguqu.
Uninzi lwabo lothusa namaqela anamava. Imida yamandla olawulo iyahluka ngokommandla, ngoko ke ukufundwa kwethegi ye-UHF kwiimitha ezine kwiziko lase-US kunokufunda mfutshane eYurophu phantsi kwemithetho engqongqo ye-ETSI. Uxinaniso ludala owalo umgibe: pakisha abafundi abaninzi kakhulu kwindawo enye kwaye bayaphazamisana kwaye bayangqubana kwiithegi, ukuthoba ukuthembeka ngelixa kunyuka ixabiso. Olunye uphononongo olujongwe ngontanga{3} lufumanise ukuba ukubekwa komfundi ngabom kunokufikelela kuncwadi olupheleleyo nge-46–47% yabafundi abambalwa kunoyilo olungevayo (Iinzwa ze-MDPI nge-PMC). Emva koko kukho "ithegi efihliweyo", apho ithegi ihlala ngokwasemzimbeni ngaphakathi kwendawo efundwayo kodwa ingaphenduli ngenxa yokubonakaliswa kweendlela ezininzi.
I-NFC iphethe eyayo inguqulelo yesifundo esifanayo, kwaye ibonisa okomzuzwana xa ithegi idibana nentsimbi okanye ifowuni eyahlukileyo. Ngenxa yokuba ukubekwa kwe-eriyali ye-NFC kuyahluka ukusuka kwimodeli ye-handset ukuya kwelandelayo, ileyibhile elungiselelwe ukufunda kwiisentimitha ezine ngokuchasene nefowuni enye inokuphulukana nesentimitha okanye ngaphezulu koluhlu olusebenzisekayo ngokuchasene nenye; kwaye kumphezulu ongenanto wealuminiyam onje ngetyesi yesixhobo okanye ipaneli yomatshini, inlay eqhelekileyo inokuyeka ukuphendula ngokupheleleyo ngaphandle kokuba -kuyilo lwentsimbi. Yiyo loo nto, kwibhentshi yethu, sifanelekela yonke ithegi ye-NFC ngokuchasene neeklasi ezininzi ze-handset kwaye ngokuchasene nomgangatho wokwenyani oya kuhlala kuwo, emva koko uyilwe kuluhlu olusebenzayo lweesentimitha ezimbini ukuya kwezintathu mfutshane kunomzobo welebhu. Usuku iithegi zomthengi zifundeka ngokugqibeleleyo kwi-ofisi yethu kwaye ngamaxesha athile kuphela kwishelufa yentsimbi lusuku oluzihlawulelayo ngokwalo.
Apho umntu ngamnye ufumana indawo yakhe
Ukukhetha phakathi kwe-RFID kunye ne-NFC yeshishini ngokuqhelekileyo kwehla kwiimeko ezintathu eziphindaphindiweyo zemizi-mveliso, kwaye azifane zihambelane.
Kumkhondo we-asethi, ugcino, kunye nemveliso-umgca wokuphuma, nantoni na apho ufunda izinto ezininzi ngokukhawuleza, umgama, ngomzamo omncinci womntu, i-UHF RFID yeyona nto ibalulekileyo. Kulapho i-RFID kunye ne-NFC ye-asethi yokulandelela inxalenye yeendlela ngokupheleleyo: Uluhlu lweesentimitha ze-NFC luyenza ibe sisixhobo esingalunganga se-forklift ehambisa ipalethi elayishiweyo ngaphaya komnyango wedokhi. I-RFID sele iwenza lo msebenzi kulo lonke ulungiselelo, ukuvelisa, kunye nokuthengisa, njengombono wethuapho i-RFID isasazwe kuwo wonke amashishiniibeka phandle.
Kulawulo lofikelelo, ukuqinisekiswa, iintlawulo, kunye nayo nayiphi na indawo apho umntu athi ngabom into ethile, uluhlu olufutshane lwe-NFC luba luphawu kunokuba luthintelwe. Impompo yenziwe ngabom, kunzima ukuyivusa ngengozi, kwaye kulula ukuyikhusela. Elo likhaya lendalo le-RFID kunye ne-NFC kulawulo lofikelelo kunye nonxibelelwano olungenanxibelelwano. Ukuba uvavanya iinketho zobungqina benkqubo yomnyango, yethuI-125 kHz vs 13.56 MHz yolawulo lofikelelo lolawulo lokucazululwa kweendlekouhamba ngetshiphu-inqanaba lokhuseleko lokwenyani, imingcipheko yokwenyani, kunye namaxabiso evolumu ngapha kwe-EM4100, MIFARE Classic, kunye ne-DESFire EV2/EV3.
Uninzi lwezityalo zokwenyani zokusasazwa zisebenzisa zombini. Ukuhamba komsebenzi omnye kunokulandelela umthwali wecandelo kwisityalo esine-UHF RFID ngelixa ithegi ye-NFC kwi-carrier efanayo ivumela ingcali ukuba icofe ifowuni kwaye itsale imbali yayo yokugcinwa kwangoko. Ukugqiba ukuba yeyiphi i-RFID kunye ne-NFC yetekhnoloji eya apho umsebenzi wokubeka, hayi nokuba / okanye umbuzo.
| Ubungakanani | UHF RFID | HF RFID / NFC |
|---|---|---|
| Uluhlu lokufunda oluqhelekileyo | Iimitha (kaninzi yi-1–10 m) | Iisentimitha (0–4 cm ye-NFC) |
| Ufunda ngokupasa | Iithegi ezininzi ngexesha elinye | Ithegi enye ngexesha |
| Ifowuni{{0}efundekayo | Hayi | Ewe (HF / NFC) |
| Eyona ifanelekileyo kwishishini | Ukulandelela ngobuninzi, ulungiselelo, uluhlu lwempahla | Ufikelelo, uqinisekiso, kwi{0}}idatha yeasethi |
| Ukubandakanyeka kwabantu | Izandla-zisimahla, ziyazenzekela | Ukucofa ngabom |
Oko itheyibhile ayinakukwenza ixabiso kukuguquguquka okugqiba izinto. Ngomthamo, i-inlay ye-UHF engenanto ibaleka malunga ne-USD 0.05–0.15 inye, ngelixa inguqulelo yesinyithi oyidingayo kwishelufa yentsimbi okanye isixhobo iqhuba malunga ne-USD 0.20–0.50, ngokuqikelelwa kathathu ukuya kahlanu ngaphezulu; Ileyibhile esisiseko ye-NFC yokumpompoza-u{7}}ukukhangela-ibhedi yesixhobo ihlala ihlala ngexabiso eliphantsi kunethegi ye-UHF erhabaxa. Kwimeko edibeneyo indleko ngokufunda okuthembekileyo, kungekhona ixabiso lentloko, yinto ebeka isigqibo.
Ayingawo onke amakhadi "akhuselekile" akhuselekile
Ukuba iprojekthi yakho ichukumisa ulawulo lofikelelo, eli candelo libaluleke ngaphezu koluhlu lweengxoxo, kuba igama elithi "ukhuseleko" lifihla ukusasazeka okukhulu. Uninzi lweenkcukacha-zexabiso eliphantsi ezithengiswe njenge-RFID kunye namakhadi ofikelelo e-NFC asasebenza kubuchwephesha betshiphu obuhlanganiswe ngaphezu kweminyaka elishumi.
Owona mzekelo ucacileyo yi MIFARE Classic. I-Crypto{6}}1 i-cipher yophulwa ngabaphandi bezemfundo ngo-2008, kodwa amakhadi ahlala ekusetyenzisweni kweshishini ngokubanzi kuba ukubuyisela izigidi zeenkcukacha kunye nabafundi kuyabiza. Umngcipheko awukho ngqiqweni. Ngo-2024, abaphandi bokhuseleko badize i-backdoor ye-hardware kwindawo esetyenziswa ngokubanzi ye-MIFARE Classic{7}}ehambelana ne-chip yosapho, efumaneka kwiinkqubo zehotele kunye ne-ofisi kumazwekazi amaninzi, eyenza ukuba i-cloning ekufutshane-ekhawulezayo.Ijenali yeRFID). Iifomathi ezindala ze-125 kHz zisebuthathaka nangoku, ziphethe isazisi esisisigxina kwaye akukho khuselo (Iqela le-NCC).
Ngoko ke mandithathe indawo eqinileyo kunothango: ukuba ufikelelo-lokucaphula ulawulo aluyichazi itshiphu, phatha ikhadi njengengafihlwanga kude kungqinwe ngenye indlela. Uphuculo oluthembekileyo yi-chip ene-cryptography yokwenyani: usapho lwe-MIFARE DESFire EV2 / EV3, kunye ne-AES encryption, ukuqinisekiswa okuhambelanayo, kunye nezitshixo ezihlukeneyo, ayinalo uhlaselo olusebenzayo lwe-cloning lwaziwa esidlangalaleni xa lusetyenziswa ngokuchanekileyo. Xa abathengi besicela ukuba senze ibakala le-RFID kunye nekhadi le-NFC lokhuseleko lwenkqubo yocango, laa ileli yile nto sihamba ngayo, yiyo loo nto sigcina i-DESFire{5}}iinketho zebakala kwizinto zethu.ulawulo lofikelelo Uluhlu lwekhadi le-RFID elibekwe ngokwenqanaba lokhuseleko lwetshiphuendaweni yokungasileli kweyona inlay inexabiso eliphantsi.
Yintoni "ukuguqulwa kwedijithali" kubonakala ngathi xa kusebenza, kwaye xa kungasebenzi
"Uguqulo lwedijithali" lubotshelelwa kwi-RFID kunye ne-NFC rhoqo ibinzana liphantse lacinywa, ngoko liyanceda ukuliqinisa kwinto ekhonkrithi. Kwisityalo esidityanisiweyo, i-RFID kunye ne-NFC kwi-chain chain inika izinto eziphathekayo isazisi sedijithali: izixhobo, abathwali, kunye neengxenye ezichaza indawo kunye nemeko yazo, ukondla i-ERP okanye i-MES ngexesha langempela, kwaye iyancipha i-lag phakathi kwento eyenzekayo kunye nomntu owaziyo ngayo.
Ummiselo utyhala ngendlela efanayo. Imithetho yePaspoti yeMveliso yeDijithali yeManyano yaseYurophu engenayo iya kunyanzela into-ukulandeleka kwinqanaba kwiindidi zemveliso engazange ibenayo, kwaye iRFID kunye neNFC iileyibhile ezikrelekrele ziba ngumaleko obonakalayo owenza ukuba ukulandeleka kwenzeke; abenzi beetshiphu sele bethumela ngenqanawaIithegi ze-NFC ezilungiselelwe iimfuno zePaspoti yeMveliso yeDijithali.
Ibali lokulumkisa lifundisa njengebali lempumelelo, kwaye kufanelekile ukwazi ngaphambi kokuba usayine nantoni na. Xa i-Walmart ikhupha isigunyaziso sayo sokuqala se-RFID kwi-2003, ukukhutshwa kwahamba phambi kwamaxabiso omabini kunye nokuthembeka kokufunda; kolunye uphando lwababoneleli ukususela ngelo xesha, ukunqongophala kwembuyekezo kutyalo-mali yayiyeyona nto ixhalabisa kakhulu, ebizwa ngokuba yi-42% yabaphenduli (IYunivesithi yaseHouston, kwiKholeji yaseBauer). Le nkqubo yayeka. Inguqulelo esebenzayo yafika phantse kumashumi amabini eminyaka kamva, xa ithegi ziye zawa ukusuka malunga namashumi amahlanu eesenti enye ukuya kwiisenti ezimbalwa ngaphezulu kweminyaka yesigunyaziso sikaWalmart, kwaye ufundo luye lwathembeka ngokwaneleyo ukuxhasa ukuchaneka kwe-inventri ngaphezulu kwe-97%, uhlobo lomfanekiso we-Auburn University's RFID Lab iye yanika ingxelo malunga nokuthunyelwa kweRFID yokuthengisa. Isifundo sesokuba abathengisi abafane bavolontiye: indlela i-RFID kunye ne-NFC esebenza ngayo kwi-Industry 4.0 imiba engaphantsi kakhulu kunokuba uqoqosho lweyunithi yakho luvale kuqala, okuthetha ixabiso lethegi, ukufundwa okuthembekileyo, kunye nembuyekezo ecacileyo, ngaphambi kokuba ulinganise nantoni na.
Ukuqala phi ngaphandle kokubheja kwifektri
Amaqela afumana i-RFID kunye ne-NFC ekuveliseni ilungelo phantse angaze avuleke ngeplanti{0}}yokukhutshwa ngokubanzi. Bathatha ityala elinye lokusebenzisa elinomda (umnyango omnye wedokhi, ibhedi enye, indawo yokufikelela enye), bathenge amakhulu ambalwa eethegi kunye nomfundi omnye, bayiqhube isithuba esingangenyanga, kwaye ubukele ireyithi yokufunda ngaphambi kokuba uzibophelele kuyo nayiphi na into enkulu. Ukuba lo mqhubi wenqwelo-moya akacacisi malunga ne-95% ethembekileyo efundwayo, ukulungiswa kusoloko kuyenye yezinto ezintathu: ukubekwa kwe-eriyali, ukukhetha ithegi, okanye umphezulu wokunyuka. Yeyiphi na, kwaye uyilungisa njani ngaphandle kokuchitha ngaphezulu-kubafundi, kuxhomekeke kwindawo yakho yokwenyani kunye nokufunda ijometri, kutshiphu kakhulu ukuyisebenza kumnyango omnye kunamashumi amane.
Ukukhetha i-hardware ukuze ilingane nemeko kunokuba ubambe umgca wekhathalogu ngexabiso eliphantsi kulapho ukuthetha nomenzi endaweni yomthengisi ufumana ukugcinwa kwayo. Sakhe iimveliso ze-RFID kunye ne-NFC ukususela ngo-2006 ukusuka kwi-3,600-square-kwindawo yeemitha, ezithunyelwa eYurophu, eMelika, kuMbindi Mpuma, nangaphaya ukusukela ngo-2012, kwaye siqhuba umsebenzi we-OEM kunye ne-ODM ukucacisa phantsi kwe-ISO{8}}imveliso elawulwayo. Ukuba imeko yakho ifuna ungqinisiso lwempompo ngabom, yethuIithegi ze-NFC ezakhelwe ixesha elifutshane-uluhlu, unxibelelwano olukhuselekileyozilumyalelo wokuqala onengqiqo; ukuba lufikelelo ulawulo okanye isazisi, yethuAmakhadi e-RFID abekwe ngokwenqanaba lokhuseleko lwetshiphukukuvumela ukuba utshatise ubungqina kumngcipheko wokwenene. Isampulu eqhutywa simahla kwimigangatho yakho kwaye abafundi baya kukuxelela ngakumbi ngenene{1}ukufaneleka kwehlabathi kunalo naluphi na ugcino lwedatha.
