Iyo RFID kiyi fob inotaridzika sechinhu chakareruka chemutsara mune yekuwana yekudzora purojekiti, diki repurasitiki tegi pane kiyi. Ichowo chikamu chinogona kunyura kuburitsa, uye hachimbokundika pamusuwo. Iyo inokundikana mavhiki apfuura, pane yekutenga odha, nguva iyo mumwe munhu anotora iyo teki inongoshanda nemakiyi akatorembera pamadziro. Panguva iyo pallet yefobs dzakadhindwa zvakanaka inosvika uye dhesiki rekumberi rinowana hafu yemagonhi isingazaruke, mutengo wakaderera weyuniti wakava chinyararire nhamba inodhura kwazvo yekota.
Nei iyo tag yakafanana ichiita zvakasiyana mukamuri yekutandarira uye mukamuri yeseva
Bvisa casing sarudzo uyerfid kiyi fob yekuwana kutongainodzika kuzvinhu zviviri zvinosarudza kuti zvinoshanda here: iyo chip mukati, uye kana iyo chip ichienderana nemuverengi wako kana kukiya. Zvimwe zvese, kubvaABS kana dehwekune yakadhindwa logo uye keyring style, iri trim. Gadzirisa chip uye encoding nemazvo uye zvimwe zvese zvinhu; vagadzirise zvisizvo uye iwe unobhadhara kaviri, kamwe chete ma tag asingavhure magonhi uye zvakare kune reorder kana relock rinotevera. Sarudzo imwe chete ndiyo inovakwa chidimbu ichi, nekuti ndicho icho vatengi vanowanzo svetuka.
Mahotera nemahofisi hazvina kufanana nedambudziko rekutenga
Mazhinji madhairekitori ekutenga anorerutsa mufananidzo pano, achinyora "mahotera, mahofisi, nzvimbo dzekurovedzera, yekupaka" sekunge zano rimwe chete rechiratidzo rakavafukidza vese. Mukuita chirongwa chehotera rfid key fob uye yekambani-kutumirwa kwehofisi zvinogara muzvinhu zviviri zvakasiyana, uye mhinduro chaiyo mune imwe kazhinji imhinduro isiriyo mune imwe.
Mahotera akavakwa akakiyiwa-uye-encoder ecosystem. Makiyi emukamuri anobva pane imwe puratifomu (Saflok, Onity, Salto nezvimwe zvakadaro), dhesiki repamberi rinoisa magwaro ega ega ekuti-mukati, uye tegi yacho inofanirwa kutaura chipu chaiyo uye fomati yedata inotariswa mutsetse wekukiya. Ndosaka zvivakwa zvakawanda zvichigara nemakadhi kwete fobs: makadhi anokodzera aripo evaenzi mafambiro ebasa, anodhinda akazara{{5}ruvara rwechiratidzo, uye akachipa kubudisa patsva kana muenzi aenda neimwe muhomwe yebhachi. Kana hotera ichienda kune fobs, mubvunzo wekusarudza haumbofa wakafanana; ndezvekuti chip uye encoding inoenderana nekiyi yakaiswa, ndizvo chaizvo maitiro ahotera yezvitupa inofanirwa kuverengerwakusati kwaitwa chero vhoriyamu.
Mahofisi emakambani anogara mune imwe nyika. Pano magwaro anodyisa sitimu inodzorwa nepakati, vashandisi vanochengeta nhare imwe chete kwemakore, uye kuwana kunopihwa nebasa uye nehurongwa: manejimendi anowana maawa akawanda, kugadzirisa kunowanikwa mushure me-maawa asi nzvimbo{2}}yekupinda zvishoma, makondirakiti anowana nguva{3}}mvumo dzebhokisi. Ayekutengesa rfid kiyi fob yekupinda muhofisi musuwoinohwina pakusimba uye kutakura zuva nezuva: inokwira pakiyiri iyo mushandi agara anayo, uye inogona kubviswa kubva padhibhodhi miniti yavanobva. Iyo yekutadza maitiro pano haisi yevaenzi mafambiro; zvicherwa zvechinyakare izvo zvisingambo dzikamiswa, uye machipisi asina simba anokopwa chinyararire. Iyo yakachena vhezheni yeiyo kupatsanurwa iri nyore kutaura; iyo inokiya mhando uye chip mhuri yainomhara pairi ndiyo inoshandura mutemo wakarongeka kuita odha yekutenga, uye izvo zvinoenderana nehardware yatove pamagonhi ako.
Frequency uye chip: chikamu cheiyo spec inosarudza chaizvo
| Band | Yakajairika kuverenga range | Pazvinokodzera | Chengetedzo chokwadi |
|---|---|---|---|
| LF 125kHz (EM4100, T5577) | ~10cm | amenity mikova, legacy systems, basic attendance | credential kutepfenyura mune yakajeka; zvakakopwa zvishoma |
| HF 13.56MHz (MIFARE, DESFire, NFC) | kusvika ~ 10 cm | kamuri nemasuo ehofisi anoda encryption | inotsigira mutual authentication; DESFire EV-kirasi ndiyo inoshanda yakachengeteka default |
| UHF | kusvika pamamita akawanda | magedhi emotokari, kupaka, kureba-kuverengwa | nyore-yakatungamirirwa; encryption inosiyana nechigadzirwa |
Kune chero chinhu chinodzivirira vanhu kana midziyo, yakavharidzirwa 13.56MHz rfid kiyi fob inofanirwa kunge iri yekusagadzika, uye 125kHz ndeyeyenhaka yekurerutsira tier, kwete yekuchengetedza. Iyo yakawanda ikurudziro yakasimba, kwete pamwe. Izvo zvisingagadzirise ndezvekuti ndeipi HF chip, iyo chaiyo MIFARE kana DESFire mutsauko muverengi wako uye kiyi inobvuma, uye ndipo panowanikwa kuwirirana, kwete frequency, inova gedhi chairo.
Mutengo unoteedzera iyo imwechete chip sarudzo kupfuura chero chakadhindwa pafob: chip tier ndiyo hombe lever pamutengo weyuniti, nekudhindwa uye kupedza sekondi iri kure. Abasic 125kHz tag uye encrypted DESFire fobhaisi kungotenga kumwe chete, uye kotesheni iyo yakachipa zvakanyanya pane yese inowanzo kukuudza kuti ndeipi chikamu chayakagara chinyararire.
Iyo gap yekuchengetedza hapana anodhinda pane chigadzirwa peji
Mapepa akajeka haawanzo vhara zvinouya zvinotevera. Mhinduro yakajairika yekuti "rinogona here rfid key fobs kuumbwa?" inosimbisa "yemazuva ano yakavharidzirwa." Mhinduro yakatendeseka ndeyekuti zvinoenderana zvachose nekuti ndeipi chip yawakagamuchira, uye nhamba inokatyamadza yevatengi havazive zvavakagamuchira.
Yakaderera-frequency 125kHz fobs inochengeta zvitupa pasina encryption uye ichitepfenyura kune chero muverengi anobvunza. A sub-$30 handheld copyer inodzokorora imwe mumasekonzi; Flipper Zero inozviita mukati mesekondi, kuburikidza nehomwe. Chaipisa kupfuura kopi pachayo ndeyekuongorora-log blind spot: chiziviso chakagadzirwa 125kHz chinoisa ID yakafanana neyepakutanga, saka system yacho haigone kuudza kopi kubva kune chaiyo tag, uye kupinda kusina mvumo kunogona kugara pasina kucherechedzwa kwemavhiki.
Yepakati-tier haina kuchengetedzeka yega. MIFARE Classic, ichiri imwe yeanonyanya kuisirwa machipisi asingabatike, anovimba neine 48-bit cipher (Crypto-1) iyo vaongorori vakabvisa makore apfuura, nemakiyi anodzoserwa mumaminitsi (Radboud University). Uye muna 2024, vatsvakurudzi vezvekuchengetedza vakanyora imba yekuseri mune inotengeswa zvakanyanya "MIFARE-inoenderana" chip, iyo Fudan FM11RF08S, uye vakaiwana mumahotera mhiri kweUS, Europe neIndia (Quarkslab). Iyo isingagadzike yekutora ndeyekuti "MIFARE inoenderana" pane quotation haina kufanana ne "yakachengeteka," uye yakachipa inoenderana chip inogona kutakura njodzi iyo label isinga taure.
Imwe ngano ine chekuita nekusiya basa: kuchinjira kunharembozha{{0}yakavakirwa kiyi yenharembozha hakusi iko kugadziridzwa kwekuchengetedza. Kutevedzera chip isina kusimba pane smartphone inongotamisa utera; haibvisi. Chengetedzo inogara muprotocol, kwete mune fomu factor.
Ipo mafob orders anoenda zvisirizvo
Anenge ese akatadza kuwanda rfid kiyi fob odha anoteedzera kumashure kune imwe yeatatu angadzivisike mafoni, uye hapana akakanganisa kugadzira.
Chekutanga kutenga pamutengo weyuniti chete. Inferior stock and thin lamination crack and fade under humidity and daily friction, uye fob inofa mumwedzi wechina inodhura zvakanyanya muzvinyorwa zvakare uye zvichemo kupfuura zvikamu zvesendi zvayakachengeta. Chechipiri ndechekubata kuenderana sedambudziko remupi rekutsvaga mushure mekutumira; apo fob "inoverenga padhesiki reshowroom asi inofira pamusuwo," chip inowanzova yakanaka; iyo encoding kana chip-type match haina kunaka, uye imwe pre-sample yekugadzira yakaedzwa pakiyi chaiyo ingadai yakaibata pasina. Yetatu ndeyekutora sarudzo nyowani ndiyo yakachengeteka, kana nharembozha kana "inoenderana" kusimudzira inogona kuunza chinyararire hutera hwawanga uchiedza kugadzira kunze.
Iyo pateni ndiyo yekupa: chimwe nechimwe cheizvi chinobatwa nedanho rakachipa rimwechete, rinotorwa kuzhinji kusati kwamhanya pane kuitevera.
Rondedzero yekusarudza iwe unogona kunyatso mhanya
Asati aita atsika rfid kiyi fob yechivakwa chehofisikana pasi pehotera kugadzirwa, simbisa zvinotevera zvinopesana nekwako chaiko, kwete dhetabheti:
- Iyo chip mhuri uye chaiyo chip modhi vaverengi vako kana makiyi vanotarisira (iyo chaiyo MIFARE kana DESFire musiyano, semuenzaniso), kwete chete "13.56MHz"
- Iyo UID fomati, kodhi yenzvimbo, uye chero encoding system yako inoda
- The encryption level ye scenario warrants: encrypted HF yemagonhi, LF chete kune yakaderera-stake amenities
- Kana mafobs achakodherwa newe pa-saiti kana{1}kare akakodherwa nemugadziri
- Yepamberi-sample yekugadzira yakaedzwa pakiyi chaiyo, muverengi, encoder uye software, kwete kuenzanisa kwebhenji
- Kune mahotera, kusimbiswa kunopesana neyakaiswa yekiyi mutsara pamberi pevhoriyamu; kumahofisi, kudzima kwakatsanangurwa uye{0}}kuburitsazve magwaro akarasika
Mhanya iro rondedzero uye rfid key fob kufambirana inomira kuita njuga uye inova bhokisi rekutarisa: hotera-tegi yekamuri inotenderwa ichienderana nekiyi ecosystem, ukuwo hofisi fob inosimbiswa zvichienderana nepuratifomu yemaneja uye nemvumo-nzira yeupenyu. Rondedzero imwechete, kusimbisa kwakasiyana.
Nei mugadziri ari kumashure kwefob akakosha kupfuura mutengo
Ese matatu ekutadza modes anogovera imwe mavambo: anotanga pakubatana uye encoding, matanho maviri iyo kambani yekutengesa inoburitsa kunze uye haigone kudzora zvizere, uye chaizvo panotangira kutadza kwakawanda. Tenga rfid kiyi fob kubva kumutengesi uye iwo matanho maviri anoitika kumwe kwausingaone. Tenga kubva kufekitari inoshandisa chip bonding uye encoding mumba-uye vanogara mukati mehuhu yehuhu.
Ndiyo nyaya chaiyo yekutsvagisa tsika rfid key fobs zvakananga kubva kumugadziri kwete kumutengesi: kutonga pamusoro pematanho maviri anosarudza kana chitupa chinoshanda, kuongorora kuzere kwekupedzisira kwete kutariswa kwemavara, uye mitengo yehurema iri pasi pechikamu chimwe chete pamitsetse yepamusoro-yevhoriyamu. Zvinoratidza mukudzokorora maitiro zvakare. Isu pachedu encoding uye kugadzikana kwakawanda kushushikana-kuyedzwa nezvirongwa zvinoronga patsva gore negore: chirongwa chekubhanga-kadhi rechikwereti maererano negwaro remagwaro emamiriyoni maviri pagore, chinonakidza-musanganisi wekubhadhara wepaki anotora mamwe mamirioni maviri, uye, kudivi refob zvakanyanya, chivako cheFrance-nyanzvi yekuwana ruzivo{}nehafu yemakore{8} inokwana 5 miriyoni zvimedu pagore. Dzokorora maodha pachikero ichocho chiratidzo chechokwadi chekuti encoding inomira nekufamba kwenguva, kwete pasample tray. Mumusika weRFID wakapamhama, unosvika US$15.6 bhiriyoni muna 2025 neIDTechEx's count, iyo{13}}frequency credequency credencerts inoshandiswa kuwana chengetedzo inoraira yakakwira pa-unit value yepamusoro pane anoraswa ma tags eUHF chaizvo nekuti chengetedzo ndiyo nzvimbo yese. Ndiyo imwe nzira yekureva kuti chip ndipo panogara mari nenjodzi.
Kana iwe uri kutsvaga kumhanya ikozvino, ino ndiyo nhanho apofekitari-yakananga RFID kiyi fob kugadzirainowana kuchengetedza kwayo: sampuli uye cheki yekuenderana inoitika pamberi pevhoriyamu, kwete mushure mekunyunyuta.
