Indlela yokukopa i-RFID Key Fob

Iifob eziphambili ze-RFID zenziwa ikakhulu ngeetshiphusi ze-RFID kunye nee-eriyali, apho itshiphu yeRFID igcina ulwazi oluthile lokuzazisa. Ngokweendlela ezahlukeneyo zonikezelo lwamandla, RFID iifobs eziphambili inokwahlulwa ibe yifobs esebenzayo ye-RFID kunye neefobs ezisebenzayo ze-RFID. I-passive RFID fobs ayifuni bhetri eyakhelwe-ngaphakathi, kwaye amandla abo avela kumaza ombane akhutshwa ngumfundi weRFID; ngelixa iifob eziphambili ze-RFID ezisebenzayo zinikwe amandla ziibhetri ezakhelwe ngaphakathi kwaye zinokufikelela ukuchongwa kude.

Kutheni ukhuphela iifobs eziphambili zeRFID?

Imfuneko yokukopa iifob eziphambili zeRFID isenokuba ngenxa yezi zizathu zilandelayo:

• Ugcino kunye nokhuseleko

• Iimfuno ezikhethekileyo: njengokwabiwa kwamalungelo okufikelela okwexeshana, umbutho wemisebenzi ethile, njl.

Ngaba ndingenza ngokwezifiso i-RFID yam yeSitshixo seFob ngokukopa umqondiso wayo?

Ewe, unokwenza ngokwezifiso zakho isiko rfid isitshixo fob ngokukopa umqondiso wayo. Kukho izixhobo ezikhoyo ezinokubamba kwaye ziphindaphinde isignali kwi-fob yakho yesitshixo, ikuvumela ukuba wenze iikopi ezininzi zokufikelela ngokulula. Qiniseka nje ukuba usebenzisa le teknoloji ngokufanelekileyo nangokusemthethweni.

Indlela yokukopa i-RFID Key Fob

Amanyathelo ukukopa RFID fobs key

• Khetha ekunene RFID ikhadi isixhobo sokukopa: Khetha ekunene RFID ikhadi isixhobo sokukopa, njengomfundi okanye isichongi, ngokweemfuno zokwenyani. Qinisekisa ukuba umgangatho kunye nokusebenza kwesixhobo kuyahlangabezana neemfuno.
• Fumana yoqobo RFID isitshixo iinkcukacha fob: Skena iqhosha loqobo le-RFID fob ngesixhobo esikhethiweyo sokukhuphela ikhadi le-RFID. Funda kwaye urekhode i-UID ye-fob engundoqo (Isichongi esisodwa) kunye nolunye ulwazi olunxulumeneyo.
• Khuphela ulwazi olungundoqo lwe-RFID fob: Beka ikhadi elitsha le-RFID okanye iqhosha le-fob kwisixhobo sokukopa. Landela imiyalelo yesixhobo ukubhala i-RFID yoqobo yolwazi lwe-fob kwikhadi elitsha le-RFID okanye i-key fob. Nika ingqalelo ukuchaneka komsebenzi ukuqinisekisa ukuba ulwazi luchanekile.
• Qinisekisa isiphumo sekopi: Skena iqhosha elitsha le-RFID fob ngomfundi okanye isichongi. Qinisekisa ukuba i-UID yayo kunye nolunye ulwazi luyahambelana noqobo lwe-RFID fob. Ukuba ulwazi luyahambelana, ikopi iphumelele.

IINTLOBO ZE-CLONED RFID CHIPS

1. Iitshiphusi zeRFID zinokuphinda-phinda ngeendlela ezintathu ezinkulu: amaza aphantsi (Lf), amaza aphezulu (Hf), kunye ne-chip ezimbini (edibanisa i-LF kunye ne-HF chips). Zonke ezi ntlobo zetshiphu ziyahambelana nezitshixo zeRFID. Ukusukela phakathi kwiminyaka yoo-1980, i-frequency ephantsi (Lf) Iichips zeRFID zisetyenziswe kakhulu. Basebenza kwindawo ye-125Khz rhoqo. Nangona abanye abantu bacinga ukuba iitshiphusi zeLF RFID zinezinye uhlobo “uguqulelo oluntsonkothileyo” okanye ukhuseleko, kwinyani, iimfuno zokhuseleko mhlawumbi zikufutshane kwiibhakhowudi kunokuba kunjalo kwezo zobuchwepheshe bangoku. Ithumela inombolo yesiriyali engenazingcingo ikakhulu. Kuba iLF RFID iyafikeleleka, elula ukuyifaka, kwaye ugcine, isasetyenziswa ngokubanzi kulwakhiwo olutsha. Ukuvala ezi zitshixo zeLF kaninzi kuthatha imizuzu embalwa, kodwa qaphela ukuba zininzi iifomati zeLF, ezinye zazo kunzima kakhulu clone kunabanye. Nje ngeziphumo, ayizizo zonke iinkonzo eziphindaphindayo ezikwaziyo ukulungiselela yonke ifomathi yeLF.
2. Iteknoloji entsha kwiinkqubo zokulawula ukufikelela, amaza aphezulu (Hf) Iitshiphusi zeRFID zisebenza kwi 13.56 Uluhlu lwefrikhwensi ye-MHz. Bakhusela ukuphindaphinda kunye nokwenza i-cloning kusetyenziswa itekhnoloji ye-encryption ebukhali. Izakhiwo ziqala ukusebenzisa lo mgangatho rhoqo nangona kubiza ngaphezulu ukuyifaka. Itekhnoloji yofihlo olupheleleyo lwefomathi yeHF ivumela inkqubo yokuphinda-phinda enokuthi ithathe naphi na 20 imizuzu ukuya 2.5 iintsuku.
3. Izitshixo zeRFID ezimbini ze-chip zisebenza kwi-13.56MHz kunye ne-125Khz iibhendi zamaza kwaye zidibanisa i-LF kunye ne-HF ubuchwepheshe.. Esi sitshixo, edibanisa iitshiphusi ezimbini zibe nye, ithandwa kakhulu zizakhiwo ezijonge ukwandisa ukhuseleko ngaphandle kokutshintshela ngokupheleleyo inkqubo ye-LF yangoku. Iingcango zokuhlala zabucala zihlala ziguqulelwa kwiinkqubo zeHF, nangona iindawo zokufikelela kuluntu (iindawo zokuzilolonga, amadama okuqubha, njl.) ukuqhubeka nokusebenza kwiinkqubo zeLF.

FAQ for RFID fobs key:

Ngaba ubonelela ngeenkonzo zokukhuphela iifobs eziphambili zeRFID?
Ukuphendula, ngokuqinisekileyo senza njalo. Nje, sinokunikezela ngeenkonzo eziphindwe kabini, kuquka i-frequency ephantsi (Lf) kunye nefrikhwensi ephezulu (Hf) Iinkonzo eziphambili ze-RFID zokuphindaphinda ngokuxhomekeke kwiimfuno zabaxumi kunye neemfuno zobuchwepheshe. Nangona kunjalo, iinkcukacha kunye nenkqubo yenkonzo yophindaphindo inokwahluka kwishishini ngenkampani.

Yintoni umahluko phakathi kwe-iButton, kazibuthe, kunye ne-RFID key fob?
Ukukwazi ukwahlula phakathi kweRFID, kazibuthe, kunye neefobs eziphambili ze-iButton zihlala zifuna inqanaba elithile lobuchule. Nantsi indlela elula yokwahlulahlula:
Iifobs eziphambili ngeRFID: Ngokwesiqhelo bane-eriyali yogqithiso lwedatha engenazingcingo kunye netshiphu yeRFID. Umfundi weRFID unokusetyenziselwa ukufumanisa ukuba uphawu lweRFID lukhona.
Iifobs zezitshixo zemagneti: Ezi zikholisa ukuza zingenayo i-RFID chip kwaye zisetyenziswa kwiinkqubo ezisisiseko zokutshixa imagnethi. Bayakwazi ukoyisa umtsalane wemagnethi.
Iifobs eziphambili ze-iButton luhlobo olulodwa lwetekhnoloji yeRFID eyenziwe nguMaxim Integrated, eyayisaziwa njenge Dallas Semiconductor. Itshiphu ye-RFID ihlala igcinwe ngaphakathi kwecasing yentsimbi ejikelezayo ebonwa kwii-iButtons. Inokufunyanwa kusetyenziswa umfundi weRFID one-iButton evuliweyo.

Isitshixo sam siprintwe ngenombolo eyodwa. Nceda uphindaphinde i-fob yam yesitshixo usebenzisa le nombolo?
Phendula: Ukusebenzisa inombolo eyodwa ebhalwe kwiqhosha, asikwazi ukuphinda ngokuthe ngqo iifob eziphambili zeRFID. Iifobs ezingundoqo ze-RFID azikho nje inani elisisiseko okanye inombolo yothotho; kananjalo baphathe ulwazi olulodwa lwe-elektroniki lokuchonga. Isixhobo sokufunda nokubhala sobuchwephesha se-RFID siyafuneka ukuze ufunde kwaye uphindaphinde ulwazi kwiifobs eziphambili zeRFID. Ukuba ungathanda ukuphindaphinda isitshixo sakho fob, sicebisa ukuba uqhagamshelane nomvelisi okanye umkhandi wokutshixa osebenza ngobuchwepheshe beRFID. Ukongeza, ukuba unomdla wokufunda ngakumbi malunga ne-RFID kunye netekhnoloji ye-NFC kunye nomahluko wabo, singakunika iinkcukacha Nfc vs rfid uthelekiso ukukunceda ukuba uqonde ngcono amandla kunye nemida yetekhnoloji nganye.

Ngaba kunokwenzeka ukuphinda amakhadi kunye nezitshixo zokufikelela kwigaraji?
Ngokuhambelana nenkqubo ethile yokulawula ukufikelela kunye nohlobo lwekhadi, sinokuphinda-phinda izitshixo zokufikelela egaraji kunye namakhadi ahambelanayo. Ngokubanzi, sinokuphinda-phinda ikhadi lofikelelo okanye i-key fob ye-low-frequency (Lf) Iinkqubo zokulawula ukufikelela kwi-RFID. Ngenxa yokuba i-high-frequency (Hf) iinkqubo zolawulo lofikelelo zisebenzisa itekhnoloji yoguqulelo oluntsonkothileyo, ukukopa kunokuba nzima kwaye kufuna ixesha elingakumbi.

Zikhona naziphi na iifobs ze-RFID ezingenanto ezithengiswayo?
Kuyenzeka ukuba uthenge iifob eziphambili zeRFID ezingenanto. Idatha ye-RFID isoloko ikhutshelwa kwaye igcinwe kwezi ngongoma eziphambili. Iimfuno zakho ziya kugqiba ukuba yeyiphi i-RFID engenanto i-fob yeqhosha elilungele wena.

Ngaba ndingasebenzisa ezinye iitshiphusi zeRFID ezizinzisiweyo ngenkonzo yakho yokukopa?
A: Inkonzo yethu yokubumba idla ngokuhambelana neentlobo ezahlukeneyo ezizinzisiweyo ze-RFID; nangona kunjalo, ifemu nganye ingaba neentlobo ezahlukeneyo zetshiphu kunye neempawu. Xa ukhetha inkonzo ye-cloning, Nceda uqhagamshelane nathi ukufumanisa ukuba sibonelela ngohlobo oluthile lwetshiphu oyifunayo.

Ndinetshiphu yetransponder/immobilizer kwisithuthi sam okanye isitshixo sesithuthuthu. Ngaba kunokwenzeka ukuba inkonzo yakho iphindaphinde ukusebenza kwetshiphu yesitshixo?
A: Kunokuba nzima kwaye mhlawumbi akukho mthethweni ukuphinda ukusebenza kwetshiphu yetransponder/immobilizer ukusuka kwisithuthi okanye isitshixo sesithuthuthu.. Ezi zitshixo kunzima ukuziphindaphinda ngaphandle kwezixhobo ezithile kunye nolwazi, kwaye umenzi unokuba nemida esemthethweni ekwenzeni oko. Kucetyiswa ukuba ngaphambi kokuzama ukukopa izitshixo ezinjalo, uqhelana neemfuno zomthetho ezisebenzayo kunye nezithintelo zomenzi.
