I-RFID Anti-I-Counterfeiting ngo-2026: Umhlahlandlela Wokutholwa Kwempahla

 

Okufanele Ukwenze I-RFID Anti-Isistimu Yomgunyathi Empeleni

 

Izikhala eziningi zabathengisi ziwisa isistimu phansi ize isendlalelo esisodwa: ithegi. Lokho kuyinkinga. Ukuthunyelwa kwe-rfid anti{2}}komgunyathi kuhlala ezindlalweni ezintathu ngesikhathi esisodwa, futhi ubuthakathaka kunoma iyiphi yazo kubhidliza yonke into.

 

Isendlalelo esibonakalayo yi-chip, i-antenna, ne-substrate. Kulapho kuhlala khona isihlonzi esiyingqayizivele, lapho ukuphazamisa{1}}idizayini ebonakalayo isebenza noma ingasebenzi, nalapho unquma khona ukuthi amalebula angaxetshulwa futhi aphinde asetshenziswe endaweni yomgunyathi. Isendlalelo sokuxhumana siyibhendi yefrikhwensi kanye{3}}nephrothokholi yesixhumi esibonakalayo somoya (UHF EPC Gen2v2, HF ISO/IEC 14443 noma 15693, NFC NDEF), kanye nanoma ikuphi ukuqinisekiswa kwe-cryptographic esongwe ngomyalo ofundiwe. Isendlalelo esingemuva siyisizindalwazi, i-blockchain yokuzikhethela noma isevisi yokuqinisekisa ifu, kanye nezibalo eziguqula ukusakazwa kokufundwayo kube yisinqumo sobuqiniso bangempela.

 

Ama-athikili amaningi avelayo uma usesha lesi sihloko agxila kusendlalelo sokuqala futhi azibe izendlalelo ezimbili nezintathu. Kulapho ukuthunyelwa kwe-rfid anti{1}}komgunyathi kwehluleka kulo mkhakha, nalapho isabelomali sokuthenga simoshakala ngemuva kwesikhathi kuphrojekthi.

 

Ukukhetha Imvamisa: UHF, HF, NFC, noma Chipless

 

Ibhendi ngalinye lisebenza ngendima ehlukile ye-rfid yokulwa-nomgunyathi, futhi ukuzama ukusebenzisa engalungile esimweni sakho iphutha elilodwa elivame kakhulu lokuthenga esilibonayo.

 

Uhlu olufundwayo lwe-UHF kanye neyunithi yezomnotho etafuleni iqondaniswe nedatha yasensimini eshicilelwe yi-Auburn University RFID Lab (I-Auburn University RFID Lab).

Ukuma kwethu: ezimpahleni eziningi (izimpahla, izinto zikagesi ezithengwayo, ukupakishwa kwezimonyo, izingxenye zezimoto,{0}}iwayini elisezingeni eliphakathi, i-OTC pharma), umaka we-UHF esebenzisa i-cryptographic Gen2v2 chip iyinketho elungile{3}}yesendlalelo se-supply. I-NFC iba usizo kuphela uma ufuna ukuthi abathengi baqinisekise ngezingcingo zabo lapho bethengiswa. Ukukhetha i-NFC iyodwa ngoba "abathengi bangayiskena" yindlela amaphrojekthi{6}}okuvikela amabhrendi agcina ngayo engasenakubonakala phezulu, ngoba asikho isisebenzi se-warehouse esizothinta i-smartphone kuwo wonke amabhokisi ku-pallet.

 

I-Chipless RFID ilingana kuphela lapho-isiginesha engakwazi ukuphindaphindeka idingeka khona kanye nevolumu yokuskena iphansi, njengobuciko{1}benani eliphezulu, okuqoqiwe, noma amadokhumenti afundwa kuzikena ezikhethekile. Ngempahla ye-rfid anti{3}}yomgunyathi engaphezu kwamayunithi ayizinkulungwane ezimbalwa ngonyaka, ayinanzuzo yezindleko noma ukuhlelwa kwe-cryptographic UHF.

 

Kodwa isiphetho sinokuchofozwa-igebe eleqa ama-athikili amaningi: iyiphi i-chip ye-UHF ethile oyikhethayo enquma ukuthi ingabe isistimu iyamelana ngempela ne-cloning, noma ibukeka sengathi yenza. Yilokho ungqimba phansi.

Ingabe I-RFID Anti-Omaka Bomgunyathi Bangenziwa Abalingiswa?

 

Yebo, amathegi acacile e-UHF EPC angenziwa. Ngokucishwa{1}}-kokufunda/umbhali weshalofu, umhlaseli angakopisha i-EPC UID emile ku-chip entsha futhi enze umgunyathi ngokusebenzisa izikena ezifanayo ezisetshenziswa izinto zangempela. Amaqembu ezemfundo akhombise ukuhlasela kaningi ngokumelene namaketanga okunikezwa kwe-pharma (I-PLOS One, Kamaludin et al., 2018).

 

Leyo yinguqulo yendaba-abathengisi bokuvikela abaqhudelanayo abakha isiphakamiso sabo, futhi abanaphutha mayelana nesisekelo. Inguqulo abaningi abangayisho ukuthi imboni yama-chip isivele ikuxazulule lokhu ngo-2014–2022.

 

I-UCODE DNA ye-NXP yaba umaka wokuqala we-UHF IC ukuhlanganisa ukusebenza-kwebanga elide ne-AES-128 yokuqinisekiswa kwe-cryptographic ethobelana ne-ISO/IEC 29167-10. Ukufunda ngakunye kubangela ukubalwa kwe-AES okusha okuboshelwe kukhiye womaka ngamunye ohlukile, ngakho impendulo erekhodiwe ayivumelekile ngokuskena okulandelayo (I-RFID Journal coverage ye-UCODE DNA). I-Impinj ilandele i-M775, esekela umyalo we-GS1 Gen2v2 Authenticate kanye ne-ISO/IEC 29167-11 (I-Impinj M775 kafushane yomkhiqizo). Kunoma iyiphi iphrojekthi ye-UHF rfid anti{1}}yomgunyathi eyethulwe ngemva kuka-2023, ukukhetha i-UID engenalutho{3}}kuyisinqumo sokuthenga kuphela, hhayi umkhawulo wobuchwepheshe.

 

Ngakho-ke inkinga ye-cloning ixazululwa kungqimba lwe-chip. Inkinga yokuhlanganisa okufanele sikhathazeke ngayo yileyo okungekho muntu othengisa ngayo: ukudluliswa komaka okusemthethweni. Umsabalalisi ongathembekile ucwengula umaka wangempela, oyiqiniso ngokufihlakala emkhiqizweni wangempela futhi awusebenzise kowomgunyathi. Umaki ungokoqobo. I-crypto iyaphuma. Ukuphazamisa{5}idizayini ye-substrate esobala kuphela, njengalokhuizakhiwo ezintekenteke{{0}ezifakwayo nezibolayo{1}}zezimpondo, ivikela kulokhu. Ibhalwe ku-US Patent 10,664,734 nakucwaningo lwe-IET Blockchain (IET Blockchain, Wiley, 2024). Ithimba lethu labadayisi libizelwa kulesi simo izikhathi ezimbili noma ezintathu ngonyaka, ngokuvamile ngemva kokulandelela umkhiqizo wemakethe-ompunga ubuyela esitolo somsabalalisi.

 

 

Ingakanani Into-I-Level RFID Anti{1}}Uhlelo Lomgunyathi Olubizayo Empeleni

 

Amaqembu okuthenga ngokuvamile afika kulesi sigaba kuqala. Sikubeke endaweni yesihlanu ngamabomu, ngoba izindleko zesixazululo se-rfid -somgunyathi zinengqondo kuphela uma usunciphise ukukhetha kwe-chip.

 

Kuwo wonke amaphrojekthi esiwathumele wezimpahla, izimonyo, namaphrojekthi wokuvikela wemikhiqizo ye-OEM electronics{0}}, isitaki sezindleko sibukeka kanjena. Ama-inlays nezitikha ezimanzi ze-UHF ezingenalutho, ezifanele ukuvaleka{2}} kohlu lwe-loop kanye nokubhekwa kwe-UID okuyisisekelo, kuhlala phakathi kuka-$0.05 no-$0.10 ngeyunithi ngayinye ngamanani e-oda angaphezu kwesigidi esisodwa. I-Cryptographic UHF (M775, UCODE DNA) isebenzisa u-$0.15 kuya ku-$0.40 ngeyunithi ngayinye ngamavolumu aqhathanisekayo, nge-MOQ ngokuvamile engu-100,000–500,000 kuye ngokuthi umndeni we-chip kanye nomklamo wezimpondo. I-NTAG 424 DNA yomthengi-thepha isendlalelo se-NFC ihlala kububanzi obufanayo njenge-cryptographic UHF. Umbhalo wekhodi, ukuhlanganiswa kwe-ERP kokwenza uchungechunge, ingqalasizinda yokufunda, kanye nesevisi yokuqinisekisa yamafu yengeza esinye isendlalelo phezulu.

 

Umthetho wesithupha wamaqembu okuthenga: uma intengo yakho yokuthengisa ingaphezu kuka-$15, into{1}}yeleveli ye-rfid anti{2}}yomgunyathi esebenzisa i-cryptographic UHF ihlala ngaphansi kuka-2% weyunithi yezindleko. Ngaphansi kwe-$15 izibalo ziyaqina ngaphandle uma usebenzisa i-UHF eyisisekelo ngokubheka isizindalwazi, esinenkinga yokuhlanganisa esisanda kudlula kuyo. Yingakho{7}}izimpahla ezihambayo eziphansi{8}ezihamba kancane zingavamile ukusebenzisa into eyimfihlo-yezinga le-RFID; esikhundleni salokho banqwabelanisa kwileveli{10}}yezinhlamvu. Okwentengo yamanje{12}}kwiyunithi yonkanaI-UHF inlay emanzi, isitika, ubucwebe-umaka, kanye nohlamvu lwemali-umaka wama-SKU, isicelo sesampula siwumzila oshesha kakhulu wokucaphuna okuthile ngokumelene nesici sakho sefomu.

 

Lapho I-RFID Anti-Inkohliso Seyivele Isebenza

 

Amaphethini omkhakha amahlanu avela ngokuphindaphindiwe ekusetshenzisweni esikunikeze izingxenye zakho, noma{0}}kubhalwe kahle kumaphephandaba. Benza imephu ezinqumweni ezahlukene zokuthenga.

 

Kwezemithi, i-WHO ilinganisela cishe umkhiqizo wezokwelapha ongu-1 kweyi-10 ezifundeni{2}}ezilawulwayo usezingeni eliphansi noma unamanga, ngoMeyi 2025.I-WHO Medical Product Alert N℃3/2025 ku-IMFINZI (durvalumab) engamanga e-Iran nase-Türkiyeukushayela ukuphuthuma okuvuselelwe kokuphoqelela. Kubikwa ukuthi izitsha ezingamanga bezingenazo isithako esisebenzayo. Lokhu kwalandela ngaphambiliI-WHO Medical Product Alert N℃5/2024ehlanganisa i-Armenia, iLebanon, neTürkiye. I-UHF uma kwenzeka-izinga labathumeli bemikhumbi kanye nokukhiqizwa kwe-serialization kuyunithi{2}}yezinga ledosi isiphenduke i-de facto rfid anti-i-counterfeiting architecture ekhemisi njengoba ukuphoqelelwa kwe-DSCSA kuye kwaqina.

 

Amawayini nespirithi bekuyisigaba samaphosta kusukela ekuqaleni kwawo-2010. Kuwo wonke amabhodlela-izinhlelo ze-NFC zentamo esizinikeze izinkampani zewayini zase-Europe kanye ne-APAC, amaklayenti asebenzisa le rfid anti{3}}i-architecture ye-countefeiting abika ukuncishiswa okungu-80–90% komgunyathi oqinisekisiwe kuwo wonke amashaneli okusabalalisa alawulwayo phakathi nezinyanga zokuqala ezingu-18, izinombolo ezihambisana ne-Tuscan eshicilelwe, futhi i-CG yethu ingakwazi ukukhuluma ngokuqondile nocwaningo lwethu. amabhodlela.

 

Izimpahla zesikhumba zikanokusho sezishintshele ku-NFC + ohlonze be-blockchain, okuhlanganisa nezinhlelo ze-SATO ze-APAC kanye neplathifomu ye-Swiss collectID, lapho ukusebenzisana kwethegi ngayinye kukhiqiza{1}}umlayezo obethelwe ongadlaleki futhi orekhodwe{2}kuchungechunge (Ucwaningo lwe-NFC Forum). Izinsiza zemfashini zithathe umzila ohlukile: I-Luxottica ishumeke i-UHF RFID ebhulohweni lezibuko zayo ukuze iqinisekiswe-yokuthenga ku-inthanethi, iwusizo emikhiqizweni lapho okufakwe ngaphakathi okufihliwe kudlula ilebula ebonakalayo.

 

Ama-electronics wabathengi anezinto ezisetshenziswayo abonisa isimo sezomnotho esihlanzeke kakhulu. I-STMicroelectronics eshumekwe abafundi be-NFC emizimbeni yesixubho sikagesi esifakazela amakhanda ebhulashi ashintshwayo (STMicroelectronics NFC ukusetshenziswa komgunyathi amacala). Idivayisi yokusingatha ngumfundi, ngakho-ke akukho ukuncika kwe-smartphone.

 

Iphethini kuzo zonke izigaba ezinhlanu: i-rfid anti{0}}ukusetshenziswa komgunyathi okuphumelela yileyo lapho isimo esifundiwe, isigaba se-chip, ne-substrate zikhethwe ndawonye ekuqaleni. Ukuhlanganisa imvamisa noma ukungafani kwe-substrate ezinyangeni eziyisithupha yikhona okwenza amaphrojekthi{2}}okuvikela umkhiqizo adlule isabelomali.

 

 

Izindlela Ezinhlanu Zokuhluleka Abathengisi Abaningi Ngeke Basho

 

Ngemva kweminyaka ecishe ibe ngamashumi amabili yokuhlinzeka ngezingxenye ze-RFID, nazi izinkinga zokuthumela ezivela ezingxoxweni zamaklayenti kaningi kunokuba zivela ezintweni zokumaketha.

 

Eyokuqala iwukudluliselwa komaka okusemthethweni, osekushiwo. Ama-chips e-Cryptographic awasizi uma umaki wangempela ehlutshiwe emkhiqizweni wangempela futhi wanamathela komgunyathi. Ama-substrates antekenteke kanye nokuphazamiseka{2}}okubonakalayo komklamo we-inlay kubaluleke kakhulu njengokukhethwa kwe-chip, yingakhoukwamukelwa kwelebula{0}}elibuthakathaka kusheshisiwekuwo wonke amaphakheji okunethezeka kanye ne-pharma.

 

Imodi yokwehluleka kwesibili ukushiywa ngemuva. Isevisi yokuqinisekisa yendawo eyodwa iyiphuzu elilodwa lokwehluleka. Sibuke okungenani izinhlelo ezimbili ezimaphakathi-zezigaba ziba mnyama ngale ndlela phakathi kuka-2020 no-2024. Izakhiwo ezinamasiginesha angaxhunyiwe ku-inthanethi{5}}ezinamasiginesha aqinisekisiwe noma i-blockchain anchoring iyasinda kulesi simo; ukubheka okuhlanzekile kwe-database akukwenzi.

 

Okwesithathu, "sisebenzisa i-RFID" akusho ukuthi "siyamelana nokwenza i-cloning." Ingxenye enkulu yezinto ezisetshenziswayo ezilebulwe ngokuthi i-rfid anti{1}}umgunyathi ngo-2024–2025 zisathembele ekufanisweni kwesizindalwazi esimile se-UID +, inguqulo yamaqembu ezemfundo kade ehlanganisa iminyaka eyishumi nanhlanu. Buza abathengisi ngokusobala: ingabe i-chip iyayisekela i-Gen2v2 Iqinisekisa kanye ne-ISO/IEC 29167-10/11? Uma kungenjalo, okuthengile ukulandeleka, hhayi ukuqinisekiswa.

 

Okwesine,{0}}ukwehluleka kokunamathela okubandayo. Ekuhloleni insimu ezindaweni zokugcina iwayini kanye nesitoreji esibandayo semithi esingaphansi −15℃, izinto ezinamathelayo ze-PSA ezisuselwe emanzini{3}ezisekelwe emanzini zilahlekelwa cishe u-30–40% wamandla ebhondi uma kuqhathaniswa ne--i-temperature specs yazo. Sithuthele amakhasimende kulezo zindawo kuzinto zokwakha{{8}ezisuselwa ku-acrylic noma i-cryo{9}}elinganisiwe. Ilebula elimelene{11}}nomgunyathi eliwa uma usendleleni ayiselona ilebula{12}}elimelene nomgunyathi.

 

Okwesihlanu, futhi lena iwusizo kunokuba isehluleki, amathegi angempela askenwa kaningi kunawomgunyathi. E{{1}ucwaningo lozalo luthola imikhiqizo yangempela ifundwa cishe ngama-50% amafrikhwensi aphezulu, ngoba idlula ezindaweni zokuhlola ezisemthethweni. Ukutholwa kwe-backend okudidayo kunoma iyiphi i-rfid anti{4}}uhlelo lomgunyathi kungancika kule signali kakhulu, nakuba ambalwa amabhrendi enzayo.

 

Kungani i-EU DPP 2027 Ishintsha Izibalo

 

Kusukela ngoFebhruwari 2027, i-EU's Ecodesign for Sustainable Products Regulation (ESPR) igunyaza Amaphasipoti Womkhiqizo Wedijithali wamabhethri ezimboni kanye ne-EV, ngendwangu, izinto zikagesi, ifenisha, nezinye izigaba ezimbalwa ezilandela ngo-2028–2030.
