Aluminium Foil RFID Blocking Sleeves Omulimu n'okukozesa

 

Engeri Omukono gwa Aluminiyamu Foil Gw'eziyiza Obubonero bwa RFID

 

Kaadi bw’etuula munda mu kisenge ekitambuza amazzi, ekisenge kikola nga aEkiyumba kya Faraday. Oluwuzi lwa aluminiyamu lulaga era ne lunyiga ekifo ky’amasannyalaze omusomi ow’ebweru kye yandikozesezza mu budde obutuufu okussa amaanyi mu chip ya RFID. Tewali nnimiro etuuka ku chip, tewali data eva ku kaadi.

 

Kino kikola olw’...obuziba bw’olususu, obuwanvu bwa kondakita obwetaagisa okukendeeza ku siginiini nga 63%. Ku 13.56 MHz, emirundi gy’emirimu gya kaadi z’okusasula eza NFC n’ebiwandiiko ebisinga eby’omulembe ebigezi, obuziba bw’olususu lwa aluminiyamu buli nga mm 0.018. Standard kitchen foil eddukira nga mm 0.016 obuwanvu. Kumpi ekimala.Kaadi y'ebyobusuubuzi-emikono egy'obukuumilaminate foil eno wakati wa layers z’empapula oba polymer era mu ngeri entuufu zisukka obuziba bw’olususu lumu obwa aluminiyamu, ekisuula siginiini wansi w’omusingi gw’okuyunga ogw’abasomi ba standard 13.56 MHz.

Okubuuza okumu kwe tufuna bulijjo ku Syntek kulaga okutabulwa. Omuddukanya ebifo asaba RFID-okuziyiza badge holders eri abakozi 200, ng'alaga "RFID blocking" awatali kwogera ku mirundi. Tubuuza omusomi model ki ekizimbe kyabwe kye bakozesa. Nga kitundu kya kiseera, eky’okuddamu kizuuka nga HID ProxPoint oba enkola ya 125 kHz efaananako bwetyo. Mu kiseera ekyo tulina okuba obutereevu: baffeomukono gwa kaadi ya aluminiyamuebalirirwamu 13.56 MHz n’okudda waggulu. Kijja kukuuma kaadi z'okusasula eza NFC, paasipooti za e-, n'ebiwandiiko ebigezi ebya HF mu ngeri ennungi. Tegenda kuwa shielding eyesigika ku 125 kHz proximity badges. Singa enkola yo ekola ku 125 kHz, weetaaga ekigendererwa ekigatta ekitambuza emitendera mingi-ekizimbibwa olw'okukendeeza ku firikwensi entono, era ekyo kika kya bikozesebwa eky'enjawulo nga kiriko emiwendo egy'enjawulo.

Passive Shielding Sleeves vs. Active Blocking Cards: Ekwatagana n'okuteekebwa mu nkola mu kitongole

 

Ebika by'ebintu bibiri bifuna lumped wansi wa "RFID blocking," naye enkola zino kumpi tezirina kye zifaanaganya. Okubatabula ku order y’okugula nsobi nnyangu era nga egenda bubi.

 

Ekizibu kiraga mu mbeera za kaadi eziwera-. Jamming card’s effective range eri nga cm 2 okuva ku ngulu kwayo. Teeka kaadi y’okuyingira, kaadi y’okusasula, ne kaadi y’okuyita mu kifo kimu, era jammer eyinza obutatuuka ku byonna ebisatu. Okukubaganya ebirowoozo ku mikutu gy’ebyokwerinda mu byuma ebikozesebwa, omuli n’akawuzi ka 2025 akakwata ku Linus Tech Tips community board, kuwandiise emisango nga kaadi emu ey’enjawulo wakati wa jammer n’ebbaluwa egenderere ye yaleetera jammer okulemererwa. Bammemba ba Dangerous Things Forum kino bongedde okukinoonyerezaako nga balina ebiwandiiko bya HID iClass.

 

Omukono oguyitibwa passive sleeve gumalawo enkyukakyuka eyo. Oba kaadi eri munda mu kisenge ekitambuza oba si bwe kiri. Osobola okukakasa okubikka mu maaso, era osobola okukigezesa mu sikonda kkumi: teeka kaadi mu, kwata omukono ku musomi wo. Singa omusomi tasobola kuzuula kaadi, omukono gukola.

 

Ku pulogulaamu za badge z’ebitongole, emikono giwangula ku kuteebereza: osobola okugigabira abakozi 300 n’omanya nti buli emu ekola mu ngeri y’emu. Jamming cards zisinga kukola ku kukozesa waleti y’omuntu ku bubwe, ng’okuyingiza n’okuggya kaadi ku mikono ssekinnoomu kizibuwalira mangu.

 

Syntek ekola ekintu ekiyitibwa passiveSiginini ya RFID-ebintu ebiziyizamu nkola zombi eza kaadi-omukono ne paasipooti-abalina. Mu kiseera kino tetukola kaadi za jamming ezikola.

 

Obulabe bwa Access Card Obuliwo Mu butuufu

 

Buuka ekitundu kino bw’oba ​​omanyi dda enjawulo wakati w’obufere bw’okusasula nga tolina kukwatagana n’okukola cloning ya access card. Ebintu ebyo ebibiri bwe biba biwulikika ng’ekizibu kye kimu, sigala ng’osoma.

Ne HID's most current high-security credential, Seos, erina obunafu obuwandiikiddwa. Olupapula olwafulumizibwa mu 2023 nga luyita mu kibiina ky’ensi yonna ekya International Association for Cryptologic Research (IACR ePrint 2023/450, Sam Haskins ne Trevor Stevado) lwalaga okulumba kwa relay ku HID Seos nga bakozesa ebikozesebwa eby’obusuubuzi off-the-shelf omuli ne Proxmark3 RDV4. Obulumbaganyi buno bwakozesa yintaneeti ng’omugongo gwa relay, nga gulina nodes bbiri ezikwatagana: emu yateekebwa okumpi ne kaadi entuufu, endala okumpi n’omusomi ekigendererwa. Abanoonyereza bano basumuludde oluggi mu laabu yaabwe ate nga kaadi ekkirizibwa esangibwa mu kiromita nga 1,960 okuva we bali. Obulumbaganyi buno bwali bwetaagisa wansi w’eddakiika emu okubeera okumpi ne kaadi mu butanwa, embeera etegeerekeka ddala mu kisenge kya ofiisi ekigatta oba lifuti ya paakingi.

 

Omukono oguziyiza RFID tegutereeza ensirifu emenyese. Kye kikola kwe kumalawo eddirisa ly’okumpi. Singa ekiwandiiko ekikakasibwa kiba munda mu kisenge kya Faraday buli lwe kiba nga tekiyanjulwa nnyo eri omusomi, omulumbaganyi tayinza kutandikawo mutendera gwa relay oba cloning mu kifo ekisooka. Ku bibiina ebiddukanya enkola ya badge ey’edda n’ebiseera by’okulongoosa ebipimiddwa mu myaka, kino kye kipiimo ky’okuziyiza eky’omubiri ekisinga obutono-omuwendo ekiriwo.

 

Okumanya ebisingawo ku ngeri tekinologiya wa RFID gy’akwataganamu n’emirimu gya buli lunaku, laba okulambika kwaffe kuenkola ya RFID eya bulijjo mu makolero gonna.

 

 

Awali Credential-Emikono gy'Obukuumi Edda Nsonga ya Standard

 

Si buli kibiina nti bino bibitwala ng’eby’okwesalirawo.

Procurement Spec Yo Kye Y'erina Okwogera Nga Tonnakkiriza Supplier

 

Emiko gy’ebintu egisinga tegijja kukuwa by’olina okusalawo. Bino bye bibuuzo ebitaano ebisaanira okubuuzibwa nga tonnakkiriza kusaba kwa sampuli.

 

 

Ensonga y’okulaga	Ebikwata ku byetaago
1. Bbandi ya frequency eriko engabo	Eyogerwako nga nnamba. "Blocks RFID" si kitegeeza. Olina okulaba "13.56 MHz," "125 kHz," oba "emirundi ebiri-".Emikono gya Syntek egya mutindo giweebwa ekipimo kya 13.56 MHz (HF/NFC) ..
2. Ebitonde by’ebintu	Buuza nti oluwuzi olutambuza (conductive layer) lukoleddwa mu ki. Enzimba ya Syntek: empapula ezisiigiddwa ebweru, oluwuzi oluziyiza olupapula lwa aluminiyamu, munda mu firimu ya PE. Etayingiramu mazzi era tesobola kukutuka-.
3. Okukwatagana mu bipimo	Emikono girina okubeera n’ebipimo bya ISO/IEC 7810 ID-1 (85.6 × 53.98 mm). Sayizi za Syntek eza mutindo: mm 88 × 59 ku kaadi, mm 140 × 97 ku paasipooti.
4. Obuziba bw’okuggulawo emikono	Ekiyumba kya Faraday kikola nga kiwedde. Ekisenge ekitali kiwanvu nga kireka olukonko olw’okungulu olwa antenna ya kaadi nga lulabika kijja kusobozesa abasomi ab’amaanyi okukwatagana ne chip.
5. MOQ & Obudde bw'okukulembera	Sampuli za bwereere (omuguzi asasula okusindika), MOQ ebitundu 500 ku mikono egya bulijjo, 1,000 ku custom-printed. Obudde bw’okukulembera ennaku z’omulimu 7 ku 15. Okusasula ng’oyita mu PayPal, T/T, oba Alibaba.

 

Sleeve Eno Ky'ekola n'Ekitakyusa

 

Tekikuuma data mu ngeri ey’okusiba. Tekakasa bakozesa. Terongoosa protocol yo eya legacy card. Singa enkola yo ey'okufuga okuyingira ekola MIFARE Classic, omukono tegujja kufuula ensirifu eyo obutamenya.

 

Kye kikola kwe kuggyawo eddirisa. Sikonda kkumi n’ettaano omukozi wo z’atambula mu paakingi ng’asibye badge etaliiko shielding ku musipi gwe? Wano we watandikira olulumba lwa relay. Omukono guggalawo ekituli ekyo. Omuwendo gwa buli-yuniti guli wansi wa ddoola, okuteekebwa mu nkola tekyetaagisa nkyukakyuka mu bikozesebwa, era kigerageranya n'ekiragiro ky'okugula kimu. Ku maneja w’ekifo amanyi nti okulongoosa kaadi kuli mu cycles ssatu ez’embalirira, ekyo kiba bridge ensaamusaamu.

 

Syntek ekuwa sampuli ez'obwereere nga tezinnaba -okufulumya osobole okugezesa ku nkola yo eya badge yennyini nga tonnaba kwewaayo ku voliyumu. Tuweereze emirundi gya kaadi, obungi obubalirirwamu, n’ebyetaago byonna eby’okukuba ebitabo. Tujja kukakasa okukwatagana era tujja kusindika sampuli mu nnaku.
