RFID VIP Lanyards: Zomwe Zimateteza Kupezeka Kwa Zochitika (ndi Zomwe Zimawoneka Zotetezeka)

Yendani chochitika chilichonse chachikulu ndipo lanyard ya VIP ndiye chitsimikiziro chowonekera kwambiri patsamba. Komanso, nthawi zambiri kuposa ayi, ndi amene amafufuza pang'ono pa dongosolo logulira. Chizindikiro, mtundu, chip "chofikira": chovomerezeka. Kusiyana kumeneku pakati pa momwe chizindikiritso chamtengo wapatali chimawonekera ndi zomwe RFID VIP lanyard imakhazikitsa ndipamene mavuto ambiri ofikira ku VIP amayambira.

 

Izi zalembedwera eni ake chisankho: otsogolera zochitika, -oyang'anira chitetezo pamasamba, matimu amalo, ndi ophatikiza akuwonetsa ziyeneretso zamakonsati, misonkhano, ndi magawo olamulidwa. Mfundo apa sikuti ndikugulitseni pa RFID. Ndiko kukuthandizani kuti muwuze mbiri yomwe imateteza gawo la VIP ku lomwe limangowonekera.

 

 

Lanyard ikhoza kuchotsedwa, ndipo izi zimasintha funso lonse lachitetezo

 

Ichi ndi chokhumudwitsa chomwe ambiri ogulitsa amadumpha m'mbuyomu. Lanyard, mwa mapangidwe ake, amatha kuchotsedwa. Pomwe wogwirizira weniweni atsegula chipata, zovomerezeka zimatha kutsika ndikudutsa mpanda kupita kwa wina yemwe akudikirira panja. Yatsani kutentha-chamba chakumanja chotsekedwa chomwe chimawonongeka pakuchotsedwa, aRFID lanyard vs wristbandkufananiza kwenikweni ndi funso limodzi lobisika: kusamutsa. Wristband imakana kupita{1}}mmbuyo mwadongosolo; lanyard alibe. Ngati pass{3}}back resistance ndiye cholepheretsa chanu choyamba, chathuRFID wristbands zachikondwerero ndi kufika-masiku ambirindi mawonekedwe opangira izo.

 

Palibe mwa izi chomwe chimalepheretsa lanyard. Icho chimachisintha icho. Lanyard imapeza malo ake chifukwa imavala bwino kwa masiku angapo, imatulukanso m'masekondi, ndipo imawirikiza mwachilengedwe ndi choyika baji ndi chithunzi cha ID. Chomwe sichingachite ndikukakamiza anthu kuti adziwike okha.

 

Malo anga osasunthika pambuyo pa zaka zomanga izi: chingwe chochotseka chomwe chimatsimikiziridwa ndi nambala ya chip sichikhala chowongolera, ndichokongoletsa chokhala ndi zolinga zabwino. Kuti mukhale ngati chitetezo, chizindikiritso cha VIP pa lanyard chiyenera kulumikizidwa ndi chizindikiritso cholembetsedwa, komanso kumaso komwe kuli-zipata zamtengo wapatali.

Chip lottery: chifukwa chiyani "RFID lanyard" pa mawu sizitanthauza kanthu

 

 

Zambiri zogulira zimati "RFID lanyard" ndikuyimira pamenepo. Mzere umodziwo umabisa kusankha kofunikira kwambiri pakumanga konse, chifukwa "RFID" imatambasula tchipisi tomwe tili padera pachitetezo.

 

Chosakhazikika chomwe mavenda amafikira-zotsika mtengo nthawi zambiri amakhala MIFARE Classic{1}}chipu yabanja, kapena "MIFARE-yogwirizana" yopanda chilolezo. Crypto1 cipher ya banja limenelo idasweka zaka zapitazo ndipo ikhoza kugonjetsedwa ndi zida zotsika mtengo, zopezeka kwambiri. Kenako zidafika poipa kwambiri: mu 2024, ofufuza adawulula kachipangizo kakang'ono m'mamiliyoni a Fudan FM11RF08S ndi FM11RF08 chips chomwe chimalola wowukirayo kutengera khadi patangotha ​​​​mphindi zochepa zakuyandikira, ndipo adapeza kuti tchipisi tidafalikira mwakachetechete kumakina olowera ku US ndi Europe.SecurityWeek). Wogula yemwe adaitanitsa "custom RFID lanyard" osatchula chip akhoza kukhala akugwira izi ndipo sakudziwa.

 

Pali yachiwiri, modekha yolephera: machitidwe omwe amatsimikizira pa UID ya chip yokha. UID sichinsinsi. Ma tag opanda kanthu, olembedwa amalola aliyense kukhazikitsa UID, kuti UID-owerenga yekha angapusitsidwe ndi munthu wina yemwe angawononge ndalama kuti asinthe. Kuti mumve zambiri za momwe mabanja a chip ndi ma frequency amapangira kugwiritsa ntchito zenizeni, zathuchiwongolero cha RFID chip ndi kusankha kovomerezekaamayenda panjira zamalonda. Pantchito ya VIP chotengeracho ndi chachifupi: banja la chip ndi njira yotsimikizira, osati mawu oti "RFID," sankhani ngati mbiri yanu ikukana kupangidwa.

 

Kusankhidwa kwa chip, poyerekeza

Lamulo logwira ntchito: ngati lanyard imayang'anira kulowa kudera loletsedwa, chitsimikizirocho chimakhala mumzere wa DESFire kapena NTAG 424 DNA, wokhala ndi makiyi osiyanasiyana paumboni uliwonse kotero kuti kusokoneza tag imodzi sikuuza wowukira chilichonse chotsatira. Lingaliro limodzi lokhalo limachita zambiri pachitetezo cha VIP kuposa ma premium weave kapena mtundu wamtundu uliwonse.

 

Kumene lamuloli limakhala loyenera ndilofunika kwambiri pazochitika zonse-zamasiku ambiri, chifukwa kutulutsanso lanyard ya VIP yomwe inatayika pa tsiku lachiwiri kumatanthauzanso-kupereka makiyi osiyanasiyana pachipata, osati kungosindikiza lamba watsopano: zosintha zambiri sizimatchulidwa ndipo zomwe zimasankha mwakachetechete ngati "makiyi osiyanasiyana" atha kulumikizidwa ndi khomo lamoyo. Titumizireni mapu a zone ndikutulutsanso cadence ndipo tidzalemba gawo lomwe chipata chilichonse chikufunika.

Gawani motengera zochitika. Polowera munthu kapena pakhomo la zoni, baji ya zochitika za NFC ndiye chida choyenera, chifukwa kuwerengeka kwakufupi kumapangitsa kuti pompopiyo akhale dala, kukhala wovuta kulumphira pagulu la anthu, komanso kukhala kosavuta kuphatikiza ndi -chowonadi chazithunzi, kuyika komwe kumapangitsa mbiri ya RFID ya VIP ndi mwayi wofikira kumbuyo kukhala chinthu chomwe woyang'anira angadalire. Pamaunikidwe amayendedwe mkati mwamalo, monga nthawi yokhala mchipinda chochezera kapena kuyenda pakati pa madera, kuchuluka kwa mawerengedwe a UHF kumasungidwa pogwira zidziwitso popanda kuyimitsa.

Kuthamangitsa chitseko cholimba patali-mitundu yosiyanasiyana ya UHF kumapangitsa kuti palibe amene angakufotokozereni: ma VIP angapo amangidwa pakhomo lopapatiza, ma tag awo amawombana ndi owerenga, ndipo makina amatsimikizira munthu wolakwika, kapena palibe aliyense.

 

Zomwe kutumizidwa kwenikweni zimatsimikizira, ndi zomwe ochepa amawulula mwakachetechete

Kufotokoza lanyard ya VIP yomwe imakhazikika

 

Zowopsa zomwe zili pamwambazi zimasanduka nthunzi pa nthawi yodziwika bwino, malinga ndi zomwe zatchulidwazo zimatchula zinthu zofunika osati zomwe zimajambula bwino. Kuti mukhale ndi lanyard ya RFID pamisonkhano kapena yoyendetsedwa-kufikira zochitika, limbikirani pazinthu izi:

 

• Banja la Chip ndi gawo lina lolemba: DESFire EV2/EV3 kapena NTAG 424 DNA pachidziwitso chilichonse chomwe chimatsegula malo oletsedwa, osatchulidwa "MIFARE yogwirizana."
   
• Kusiyanasiyana kofunikira ndi kabisidwe zatsimikiziridwa: pa-makiyi otsimikizira, makiyi a AES-kutengera kutsimikizika, ndi owerenga kuphatikiza ndi backend omwe amatsimikizira mobisa m'malo mwa UID.
   
• Identity identity: kulembetsa kulumikiza chizindikiritso chilichonse kwa mwiniwakeyo, ndikutsimikizira chithunzi pazipata zapamwamba kwambiri-zamtengo wapatali.
   
• Miyezo ndi kulimba kwake: ISO/IEC 14443 ya HF/NFC kapena ISO/IEC 18000-63 ya UHF, kuphatikizapo tamper-yowonekera, thukuta- ndi UV-yosagwira ntchito yomwe imatha kuvala masiku ambiri.
   
• Kutsekeka ndi chitetezo chokwanira: kuthawa kwa chitetezo cha khosi, poyesedwa motsutsana ndi chenicheni chakuti kumasulidwa kosavuta kumathandizanso kusamutsa, kotero pamene mumalola kupatukana, tsamirani kwambiri pakumanga.

 

Chidziwitso chomwe chimakwirira asanu omwe akuwunikiridwa. Kumene kudali kokulirapo ndi kuyanjana kwapakati pawo: kutseka kodukizadukiza ndi kupita mwamphamvu-kukokera kumbuyo komwe kumakokerana wina ndi mnzake, ndipo yomwe ipambana imadalira masanjidwe a chipata chanu komanso ngati mutha kutsimikizira chithunzi pamwamba pake. Tradeoff imeneyo ndi gawo lomwe mndandanda wa template sungathe kukukonzerani; titumizireni mndandanda wa zone ndipo tidzanena kutseka ndi kumangidwa kuti zigwirizane nazo.

 

Kumene umboni umachokera kuzinthu

 

Ili ndi gawo la pulogalamu yamapulogalamu chabe-otsatsa omwe amatsogozedwa sangayankhe moona mtima, chifukwa amagula zolowetsamo momwe aliyense amachitira. Fakitale ikamanga tchipisi take ndikuyimba tinyanga zake, kusankha kwa chip kumasiya kukhala chinsinsi chokokedwa m'bin. Pamizere yathu, kupindika kwa mlongoti kumakhala ± 0.1 mm kotero kuti mtunda wowerengera umakhala wosasunthika kuchokera pa tag kupita ku tag, ndipo chitsimikiziro chilichonse chimayesedwa pafupipafupi, kuwerengeka, ndi kukhulupirika kwa data isanatumizidwe, momwemonso chip chokhazikika cha Classic chimasungidwa kuti chisasungidwe. Ulamuliro umenewo, mothandizidwa ndi ISO9001 ndi njira za CE komanso zaka pafupifupi makumi awiri za mbiri yomanga, ndi kusiyana pakati pa wogulitsa amene angatchule chip yanu ndi amene akuyembekeza kuti simudzafunsa.
