Momwe mungakoperere RFID Key Fob

RFID key fobs makamaka amapangidwa RFID chips ndi tinyanga, momwe chipangizo cha RFID chimasungira zidziwitso zenizeni. Malinga ndi njira zosiyanasiyana zoperekera mphamvu, RFID key fobs atha kugawidwa m'makiyi osavuta a RFID ndi ma RFID makiyi akugwira. Passive RFID key fobs safuna mabatire omangidwa, ndipo mphamvu yawo imachokera ku mafunde a electromagnetic opangidwa ndi owerenga RFID; pomwe makiyi a RFID omwe amagwira ntchito amayendetsedwa ndi mabatire omangidwa mkati ndipo amatha kuzindikira zakutali.

Chifukwa chiyani kukopera ma RFID key fobs?

Kufunika kotengera makiyi a RFID kungakhale chifukwa chazifukwa zotsatirazi:

• Zosunga zobwezeretsera ndi chitetezo
• Kugawana kwa ogwiritsa ntchito ambiri
• Kupititsa patsogolo kumasuka
• Kuchepetsa kuganizira za mtengo
• Zosowa zapadera: monga kugawa ufulu wofikira kwakanthawi, kulinganiza ntchito zinazake, etc.

Kodi Ndingasinthire Mwamakonda Anga RFID Key Fob Potengera Chizindikiro Chake?

Inde, mukhoza makonda anu makonda rfid key fob potengera chizindikiro chake. Pali zida zomwe zimatha kujambula ndi kubwereza chizindikiro kuchokera pakiyi yanu, kukulolani kuti mupange makope angapo kuti muwapeze mosavuta. Ingotsimikizirani kuti mukugwiritsa ntchito ukadaulowu moyenera komanso movomerezeka.

Masitepe kukopera RFID key fobs

• Sankhani yoyenera RFID khadi kukopera chipangizo: Sankhani yoyenera RFID khadi kukopera chipangizo, monga owerenga kapena chizindikiritso, malinga ndi zosowa zenizeni. Onetsetsani kuti mtundu ndi ntchito ya chipangizocho zikukwaniritsa zofunikira.
• Pezani chidziwitso choyambirira cha RFID key fob: Jambulani fob yoyambirira ya RFID ndi chipangizo chosankhidwa cha RFID chokopera khadi. Werengani ndikujambulitsa UID ya fob (Chizindikiritso Chapadera) ndi zina zofananira.
• Koperani zambiri za RFID key fob: Ikani RFID khadi yatsopano kapena fob ya kiyi pa chipangizo chokopera. Tsatirani malangizo a chipangizocho kuti mulembe zambiri za RFID key fob mu RFID khadi yatsopano kapena fob key. Samalani kulondola kwa ntchitoyo kuti muwonetsetse kuti zomwe zalembedwazo ndi zolondola.
• Tsimikizirani zotsatira zake: Jambulani kiyibodi yatsopano ya RFID ndi chowerengera kapena chozindikiritsa. Tsimikizirani kuti UID yake ndi zina zambiri zikugwirizana ndi fob yoyambirira ya RFID. Ngati chidziwitsocho chikufanana, kukopera kwapambana.

MITUNDU YA MA CLONED RFID CHIPS

1. Tchipisi za RFID zitha kubwerezedwa m'njira zazikulu zitatu: pafupipafupi otsika (LF), high frequency (HF), ndi dual chip (zomwe zimaphatikiza tchipisi ta LF ndi HF). Mitundu yonse ya chip iyi imagwirizana ndi makiyi a RFID. Kuyambira pakati pa 1980s, otsika pafupipafupi (LF) RFID chips zakhala zikugwiritsidwa ntchito kwambiri. Amagwira ntchito m'dera lafupipafupi la 125Khz. Ngakhale anthu ena amaganiza kuti tchipisi LF RFID ndi mtundu wina wa “kubisa” kapena chitetezo, kwenikweni, zofunikira zachitetezo mwina zili pafupi ndi ma barcode kuposa momwe zilili ndiukadaulo wamakono. Imatumiza nambala yopanda zingwe makamaka. Chifukwa LF RFID ndi yotsika mtengo, yosavuta kukhazikitsa, ndi kusamalira, ikugwiritsidwabe ntchito kwambiri pomanga zatsopano. Kutseka makiyi a LF awa nthawi zambiri kumatenga mphindi zochepa, koma dziwani kuti pali mitundu yambiri ya LF, zina zomwe zimakhala zovuta kuzipanga kuposa zina. Zotsatira zake, si ntchito zonse zobwereza zomwe zimatha kutengera mtundu uliwonse wa LF.
2. Ukadaulo waposachedwa kwambiri pamakina owongolera mwayi, high frequency (HF) RFID chips imagwira ntchito mu 13.56 MHz frequency range. Amayang'anira kubwereza ndi kupanga ma cloning pogwiritsa ntchito ukadaulo wamakono wa encryption. Nyumba zikuyamba kugwiritsa ntchito muyezo uwu nthawi zambiri ngakhale zimawononga ndalama zambiri kuziyika. Ukadaulo wathunthu wamtundu wa HF umalola kubwereza komwe kungatenge kulikonse 20 mphindi kuti 2.5 masiku.
3. Makiyi a Dual-chip RFID amagwira ntchito mu 13.56MHz ndi 125Khz ma frequency band ndikuphatikiza ukadaulo wa LF ndi HF. Kiyi iyi, zomwe zimaphatikiza tchipisi ziwiri kukhala chimodzi, imakondedwa ndi nyumba zomwe zikuyang'ana kuti ziwonjezere chitetezo popanda kusinthiratu machitidwe awo apano a LF. Zitseko zanyumba zapayekha nthawi zambiri zimasinthidwa kukhala machitidwe a HF, ngakhale malo ofikira anthu (masewera olimbitsa thupi, maiwe osambira, ndi zina.) pitilizani kugwira ntchito pamakina a LF.

FAQ kwa makiyi a RFID:

Kodi mumapereka ntchito zokopera ma RFID key fobs?
Poyankha, Ife ndithudi timatero. Mwambiri, titha kupereka mautumiki obwereza, kuphatikiza pafupipafupi otsika (LF) ndi ma frequency apamwamba (HF) RFID key fob duplication services kutengera zofuna za kasitomala ndi zofunikira zaukadaulo. Komabe, mwatsatanetsatane ndi kachitidwe ka ntchito yobwerezabwereza zitha kusiyana ndi bizinesi ndi kampani.

Kodi pali kusiyana kotani pakati pa iButton, maginito, ndi RFID key fob?
Kutha kusiyanitsa pakati pa RFID, maginito, ndi makiyi a iButton nthawi zambiri amafuna luso linalake. Nayi njira yosavuta yowasiyanitsa:
Mafungulo ofunikira okhala ndi RFID: nthawi zambiri amakhala ndi mlongoti wosamutsa deta opanda zingwe ndi chipangizo cha RFID. Wowerenga RFID angagwiritsidwe ntchito kuti adziwe ngati chizindikiro cha RFID chilipo.
Makiyi a maginito: Izi nthawi zambiri zimabwera popanda chipangizo cha RFID ndipo zimagwiritsidwa ntchito pamakina oyambira maginito. Amatha kugonjetsa kukopa kwa maginito.
IButton key fobs ndi mtundu wapadera waukadaulo wa RFID wopangidwa ndi Maxim Integrated, kale ankadziwika kuti Dallas Semiconductor. Chip cha RFID nthawi zambiri chimakhala mkati mwa chitsulo chozungulira chomwe chimawonedwa pa iButtons. Itha kupezeka pogwiritsa ntchito owerenga RFID omwe ali ndi iButton yotsegulidwa.

Kiyi yanga yasindikizidwa ndi nambala yapadera. Chonde mutha kufananiza fob yanga pogwiritsa ntchito nambala iyi?
Yankhani: Pogwiritsa ntchito nambala yapadera yolembedwa pa kiyiyo, sitingathe kubwereza mwachindunji ma fobs a RFID. Ma RFID key fobs si nambala yokhayo kapena nambala ya serial; amakhalanso ndi chidziwitso chapadera chamagetsi. Zida zaukadaulo zowerengera ndi kulemba za RFID zimafunikira kuti muwerenge ndikubwereza zomwe zili pazida zazikulu za RFID. Ngati mukufuna kubwereza fob yanu yachinsinsi, Mpofunika kulankhula Mlengi kapena katswiri locksmith amene amakhazikika mu luso RFID. Additionally, ngati mukufuna kuphunzira zambiri zaukadaulo wa RFID ndi NFC komanso kusiyana kwawo, tikhoza kukupatsani mwatsatanetsatane nfc vs rfid poyerekeza kukuthandizani kumvetsa bwino luso ndi malire a luso lililonse.

Kodi ndizotheka kubwereza makhadi ndi makiyi olowera m'galaja?
Mogwirizana ndi kachitidwe kakuwongolera kolowera ndi mtundu wamakhadi, titha kubwereza makiyi olowera m'galaja ndi makhadi ogwirizana nawo. Nthawi zambiri, titha kubwereza mosavuta khadi yolowera kapena fob ya kiyi kuti ikhale yotsika kwambiri (LF) RFID access control systems. Chifukwa high-frequency (HF) njira zowongolera zimagwiritsa ntchito ukadaulo wapamwamba kwambiri wachinsinsi, kukopera kungakhale kovuta kwambiri ndipo kumafunika nthawi yambiri.

Pali makiyi aliwonse opanda kanthu a RFID omwe amagulitsidwa?
Ndizotheka kugula makiyi a RFID omwe alibe kanthu. Zambiri za RFID nthawi zambiri zimakopera ndikusungidwa pazida zazikuluzikuluzi. Zofuna zanu zidzatsimikizira kuti ndi foni iti ya RFID yomwe ili yabwino kwa inu.

Nditha kugwiritsa ntchito tchipisi ta RFID ndi ntchito yanu yokopera?
A: Ntchito yathu yopanga ma cloning nthawi zambiri imagwirizana ndi mitundu yosiyanasiyana ya RFID chip; komabe, kampani iliyonse ikhoza kukhala ndi mitundu yosiyanasiyana ya chip ndi mtundu. Posankha ntchito ya cloning, chonde lumikizanani nafe kuti mudziwe ngati tikupereka mtundu wa chip womwe mukufuna.

Ndili ndi transponder/immobilizer chip m'galimoto yanga kapena kiyi ya njinga yamoto. Kodi ndizotheka kuti ntchito yanu ifanane ndi magwiridwe antchito a kiyiyi?
A: Zitha kukhala zovuta komanso zosaloledwa kutengera mawonekedwe a chip transponder/immobilizer kuchokera pakiyi yagalimoto kapena yanjinga yamoto.. Makiyi awa ndi ovuta kubwereza popanda zida zina ndi chidziwitso, ndipo wopanga akhoza kukhala ndi malire alamulo pakuchita zimenezo. Iwo akulangizidwa kuti asanayese kutengera makiyi amenewa, mumadziwa zofunikira zamalamulo ndi zoletsa za opanga.
