Aluminium Foil RFID Inovhara Sleeves Basa uye Mashandisiro

 

Sei Aluminium Foil Sleeve Inovhara RFID Zviratidzo

 

Kana kadhi rakagara mukati memuvharo we conductive, iyo yakavharirwa inoita seaFaraday cage. Iyo aluminium layer inoratidzira uye inobata iyo electromagnetic munda uyo wekunze muverengi angawanzo shandisa kusimbisa iyo RFID chip. Hapana munda unosvika kune chip, hapana data rinosiya kadhi.

 

Izvi zvinoshanda nekuda kwekudzika kweganda, ukobvu hwekondukita hunodiwa kuderedza chiratidzo neinosvika 63%. Pa13.56 MHz, iyo frequency yekushanda yeNFC makadhi ekubhadhara uye mazhinji emazuva ano akangwara zvitupa, kudzika kweganda realuminium kunosvika 0.018 mm. Yakajairika kicheni foil inomhanya inosvika 0.016 mm mukobvu. Pedyo zvakakwana.Kadhi rekutengesa{0}}maoko ekudziviriralaminate iyi foil pakati pemapepa kana mapolymer layers uye kazhinji inodarika imwe kudzika kweganda realuminium, iyo inodonhedza chiratidzo pazasi pekubatanidza chikumbaridzo cheyakajairwa 13.56 MHz vaverengi.

Mumwe mubvunzo watinogara tichiwana paSyntek unoratidza kuvhiringidzika kwacho. Maneja wezvivakwa anokumbira RFID-kuvharisa mabheji evashandi mazana maviri, achitsanangura "RFID blocking" pasina kutaura frequency. Tinobvunza kuti ndeupi muverengi anoshandisa chivakwa chavo. Inenge hafu yenguva, mhinduro inoshanduka kuita HID ProxPoint kana yakafanana 125 kHz system. Panguva iyoyo tinofanira kuve takananga: yedualuminium foil kadhi sleeveyakarongerwa 13.56 MHz uye pamusoro. Ichachengetedza makadhi ekubhadhara eNFC, e-mapasipoti, uye zvitupa zvakangwara zveHF. Iyo haizopi yakavimbika kudzivirira ye125 kHz mabheji epedyo. Kana sisitimu yako ichiita 125 kHz, unoda-layer conductive composite purpose-yakagadzirirwa kudzika-frequency attenuation, uye icho chimwe chikamu chezvigadzirwa chine mitengo yakasiyana.

Passive Shielding Sleeves vs. Active Blocking Cards: Iyo Inokodzera Enterprise Deployment

 

Zvikamu zviviri zvechigadzirwa zvinodonhedzwa pasi pe "RFID kuvharira," asi maitiro acho haana chero chinhu chakafanana. Kuita kuti vavhiringike pane yekutenga odha ikanganiso iri nyore iyo inoyera zvakashata.

 

Dambudziko rinoonekwa munzvimbo-makadhi akawanda. Kushanda kwekadhi rejamming kunosvika masendimita maviri kubva pamusoro payo. Isa kadhi rekupinda, kadhi rekubhadhara, uye kadhi rekufambisa mune imwechete mubati, uye jammer inogona kusasvika ese ari matatu. Hurukuro pamusoro pemaforamu ekuchengetedza hardware, kusanganisira yakadzama 2025 tambo paLinus Tech Mazano enharaunda bhodhi, vakanyora nyaya apo imwe kadhi yekuwedzera pakati pejammer uye chinangwa chechiratidzo chakakonzera kuti jammer itadze. Zvinengozi Zvinhu Nhengo dzeForamu dzakaongorora izvi zvakare neHID iClass zvitupa.

 

Sleeve yekungoita inobvisa iyo shanduko. Pamwe kadhi riri mukati me conductive enclosure kana kuti kwete. Iwe unogona kuonesa kuvharika nekuona, uye unogona kuiyedza mumasekonzi gumi: isa kadhi mukati, bata ruoko uchitarisana nemuverengi wako. Kana muverengi asingakwanisi kuona kadhi, sleeve inoshanda.

 

Kuzvirongwa zvemabheji ebhizinesi, maoko anohwina pakufungidzira: unogona kuapa kune vashandi mazana matatu uye uzive kuti imwe neimwe inoshanda zvakafanana. Makadhi ejamming anonyanya kushanda pakushandisa chikwama chemunhu, uko kuisa nekubvisa makadhi kubva mumawoko ega ega kunokurumidza kunetesa.

Iyo Access Card Kutyisidzira Iyo Iripo Chaizvoizvo

 

Svetuka chikamu ichi kana iwe uchitoziva mutsauko uripo pakati pehutsotsi hwekubhadhara usingabatike uye kuwana kadhi cloning. Kana zvinhu zviviri izvozvo zvichiita sedambudziko rimwe chete, ramba uchiverenga.

Kunyangwe HID ine chengetedzo yepamusoro-yazvino, Seos, ine magwaro asina kusimba. Pepa ra2023 rakaburitswa kuburikidza neInternational Association for Cryptologic Research (IACR ePrint 2023/450, Sam Haskins naTrevor Stevado) rakaratidza kurwiswa neHID Seos vachishandisa{5}}sherufu yehardware kusanganisira Proxmark3 RDV4. Kurwiswa kwakashandisa internet senge relay backbone, iine mbiri dzakabatana node: imwe yakaiswa padyo nekadhi repamutemo, imwe padyo nemuverengi anotarirwa. Vatsvagiri vakavhura musuwo mulab yavo apo kadhi rakatenderwa raive makiromita 1,960 kubva kure. Kurwiswa kwacho kwaidiwa pasi peminiti imwe chete yekuva pedyo nekadhi, mamiriro ezvinhu anogoneka muhofisi yakagovaniswa imba yekutandarira kana kusimudzira kwekupaka.

 

Iyo RFID inovharira sleeve haigadziri yakatyoka encryption. Zvazvinoita kubvisa hwindo repedyo. Kana chiziviso chiri mukati meFaraday yakavharirwa pese pachiri kusiri kuratidzwa kune muverengi, anorwisa haakwanise kutanga relay kana kutevedzera kutevedzana kwekutanga. Kumasangano ane zvivakwa zvemabheji ane nguva yakakwidziridzwa yakayerwa mumakore, iyi ndiyo nzira yakaderera-inodhura iripo.

 

Kuti uwane mamwe mamiriro ekuti RFID tekinoroji inodyidzana sei nemashandiro ezuva nezuva, ona yedu yekutarisazvakajairika RFID application mumaindasitiri ese.

Izvo Sleeve Iyi Inoita uye Haisi Kutsiva

 

Iyo haina encrypt data. Haisi chokwadi vashandisi. Izvo hazvikwidziridze yako legacy kadhi protocol. Kana yako yekupinda yekudzora sisitimu iri kuita MIFARE Classic, sleeve haiite kuti encryption iite kushomeka.

 

Zvazvinoita kubvisa hwindo. Masekonzi gumi nemashanu mushandi wako anofamba nemugaraji rekupaka nebheji risina kuvharidzirwa rakadimburirwa bhandi ravo? Ndipo panotanga kurwisa kwerelay. Sleeve inovhara mukaha iwoyo. Pa-mutengo weyuniti uri pasi pedhora, kutumirwa hakudi shanduko yezvivakwa, uye kunokwana nehodha imwe chete yekutenga. Kune maneja wenzvimbo anoziva kukwidziridzwa kwekadhi kune matatu bhajeti kutenderera kure, iro rine musoro zambuko.

 

Syntek inopa mahara pre-samples ekugadzira kuitira kuti uedze uchienzanisa nebheji rako chairo usati wawedzera vhoriyamu. Titumirei kadhi frequency, huwandu hunofungidzirwa, uye chero zvinodiwa pakudhinda. Isu tichasimbisa kuenderana uye kutumira sampuli mukati memazuva.
