I-RFID Key Fobs Yamahhotela Namahhovisi: Ungayikhetha Kanjani Elungile

I-RFID key fob ibukeka njengento elula kalayini kuphrojekthi yokulawula ukufinyelela, umaka wepulasitiki omncane enkingeni yokhiye. Kuphinde kube yingxenye okungenzeka kakhulu ukuthi izike ukukhishwa, futhi cishe ayihluleki emnyango. Ihluleka emasontweni adlule, ku-oda lokuthenga, lapho othile ethatha ithegi izovele isebenze nezingidi ezivele zilenga odongeni. Ngesikhathi i-pallet ye-fobs ephrintiwe ngobunono ifika futhi ideski elingaphambili lithola uhhafu weminyango ingeke ivuleke, inani eliphansi leyunithi seliphenduke inombolo ebiza kakhulu yekota.

 

 

Kungani umaka ofanayo uziphatha ngendlela ehlukile endaweni yokwamukela izivakashi kanye negumbi leseva

 

Khipha izinketho ze-casing futhii-rfid key fob yokulawula ukufinyelelayehlela ezintweni ezimbili ezinquma ukuthi iyasebenza yini: i-chip ngaphakathi, nokuthi leyo chip ifana nomfundi wakho noma isikhiya. Konke okunye, kusukaI-ABS noma isikhumbakulogo ephrintiwe kanye nesitayela se-keyring, i-trim. Lungisa i-chip kanye nombhalo wekhodi ngendlela efanele kanti okunye okokusebenza; zixazulule futhi ukhokha kabili, kanye kumathegi angavuli iminyango futhi uphinde uhlele kabusha noma ukukhiya kabusha okulandelayo. Leso sinqumo esisodwa yilokho lesi siqephu esakhiwe ngaso, ngoba yiso kanye abathengi abavame ukweqa.

 

 

Imvamisa ne-chip: ingxenye ye-spec enqumayo ngempela

 

Ibhendi	Ibanga lokufunda elijwayelekile	Lapho ingena khona	Ukuphepha okungokoqobo
I-LF 125kHz (EM4100, T5577)	~ 10cm	iminyango yezinsiza, izinhlelo zefa, ukuya okuyisisekelo	ukusakazwa kobufakazi ngokucacile; ikopishwe kancane
HF 13.56MHz (MIFARE, DESFire, NFC)	kufika ku-10 cm	Igumbi neminyango yehhovisi edinga ukubethela	isekela ukuqinisekiswa okufanayo; Ikilasi le-DESFire EV- liwukuzenzakalela okusebenzayo okuvikelekile
I-UHF	kufika kumamitha amaningana	amasango emoto, indawo yokupaka,{0}}ibanga elide elifundiwe	lula-okuholwa; ukubethela kuyehluka ngomkhiqizo

 

Kunoma yini evikela abantu noma izimpahla, i-fid key fob ebethelwe engu-13.56MHz kufanele ibe yiyo ezenzakalelayo, futhi u-125kHz ingeyesigaba esinenzuzo yefa, hhayi esokuvikela. Lokho okuningi kuyizincomo eziqinile, hhayi mhlawumbe. Okungakuxazululi ukuthi iyiphi i-chip ye-HF, i-MIFARE ethize noma i-DESFire ehlukile yomfundi wakho nesikhiya esizokwamukela ngempela, futhi yilapho ukuhambisana, hhayi imvamisa, kuba isango langempela.

 

Izindleko zilandela leso sinqumo se-chip ngaphezu kwanoma yini ephrintwe ku-fob: i-chip tier iyisivikelo esikhulu senani leyunithi, ngokuphrinta nokuqeda isekhondi elikude. Aumaka we-125kHz oyisisekelo kanye ne-encrypted DESFire fobakukona nje ukuthengwa okufanayo, futhi ikhwowutheshini eshibhe kakhulu kunezinye ivamise ukukutshela ukuthi ihlezi kuliphi izinga buthule.

 

Igebe lokuvikela akekho oliphrintayo ekhasini lomkhiqizo

 

Amashidi akhethekile awavamile ukumboza okulandelayo. Impendulo evamile kokuthi "ingabe i-rfid key fobs ingahlanganiswa?" iqinisekisa "ezanamuhla zibethelwe." Impendulo eqotho ukuthi incike ngokuphelele ekutheni iyiphi i-chip oyitholile ngempela, futhi inani elimangalisayo labathengi alazi ukuthi bathole ini.

 

-ama-fobs angu-125kHz aphansi agcina izifakazelo zawo ngaphandle kokubethela futhi asakaze kunoma yimuphi umfundi obuzayo. Ikhophi engaphansi-ka-$30 ephathwa ngesandla iphinda eyodwa ngesekhondi; i-Flipper Zero ikwenza ngaphansi kwesekhondi, ngephakethe. Okubi kakhulu kunekhophi ngokwayo ukuhlola-i-log blind spot: isiqiniseko esihlanganisiwe esingu-125kHz sifaka i-ID efanayo neyokuqala, ngakho isistimu ayikwazi ukuhlukanisa ikhophi kumaka wangempela, futhi okufakiwe okungagunyaziwe kuhlale amasonto kungaziwa.

 

Isigaba-esiphakathi nendawo asiphephile ngokuzenzakalelayo. I-MIFARE Classic, namanje ingelinye lama-chips angaxhunywanga asetshenziswa kabanzi, incike ku-48-bit cipher (Crypto-1) abacwaningi abayihlakaza eminyakeni edlule, enokhiye obutholakala ngemizuzu.Inyuvesi yaseRadboud). Futhi ngo-2024, abacwaningi bezokuphepha baqopha umlando wezingxenyekazi zekhompuyutha ku-chip "MIFARE{2}}ehambelanayo" ethengiswa kakhulu, i-Fudan FM11RF08S, futhi bayithola emahhotela e-US, Europe nase-India (Quarkslab). I-takeaway engakhululekile ukuthi "i-MIFARE ehambisanayo" kwikhotheshini ayifani nokuthi "ivikelekile," futhi i-chip ehambisanayo eshibhile ingaba sengozini ilebula engalokothi ikhulume ngayo.

 

Enye inganekwane okufanele uyekwe: ukushintshela{{0}kukhiye weselula osuselwe kufoni akukona ukuthuthukiswa kokuvikeleka ngokuzenzakalelayo. Ukulingisa i-chip ebuthakathaka ku-smartphone kuvele kuthuthe ubuthakathaka; ayisusi. Ukuphepha kuhlala kuphrothokholi, hhayi kusici sefomu.

 

Lapho ama-fob oda empeleni engahambi kahle

 

Cishe yonke i-fid key fob oda yenqwaba ehlulekile ilandela emuva kocingo olulodwa kwezintathu ezigwemekayo, futhi alukho olunesici sokukhiqiza.

 

Okokuqala ukuthenga ngenani leyunithi kuphela. Isitokwe esiphansi kanye ne-lamination encane iyaqhekeka futhi iphele ngaphansi komswakamo kanye nokungqubuzana kwansuku zonke, kanye ne-fob efa ngenyanga yesine kubiza kakhulu ekukhishweni kabusha nasezikhalweni kunezingxenye zesenti ezilondoloziwe. Okwesibili ukuphatha ukuhambisana njengenkinga yomphakeli ukuthola ngemuva kokuthunyelwa; lapho i-fob "ifunda etafuleni le-showroom kodwa ishonela emnyango," i-chip ngokuvamile ihamba kahle; uhlobo lombhalo wekhodi noma lwe-chip{2}}olufanayo alulungile, futhi isampuli{3}}eyodwa yokukhiqiza ehlolwe kukhiye wangempela bekungeke kubambe lutho. Okwesithathu ukucabanga ukuthi inketho entsha iyona ephephe kakhulu, lapho ukuthuthukiswa kweselula noma "okuhambisanayo" kungaphinda kuthule buthule lobo buthakathaka obuzama ukubuklama.

 

Iphethini iwukunikezwayo: konke kwalokhu kubanjwa yisinyathelo esishibhile esifanayo, esithathwe ngaphambi kokugijima kwenqwaba kunokusilandela.

 

Uhlu lokuhlola lokukhetha ongaluqalisa

 

Ngaphambi kokwenza acustom rfid key fob for an office buildingnoma iphansi lehhotela elizokhiqizwa, qinisekisa okulandelayo ngokumelene nendawo okuyo yangempela, hhayi imininingwane yedatha:

 

• Umndeni we-chip kanye nemodeli ye-chip enembile elindelwe abafundi bakho noma izingidi (isibonelo esithile esihlukile se-MIFARE noma i-DESFire), hhayi nje "13.56MHz"

 

• Ifomethi ye-UID, ikhodi yendawo, nanoma yikuphi ukubhala ngekhodi okudingwa yisistimu yakho

 

• Izinga lokubethela ligunyaza isimo: i-HF ebethelwe yeminyango, i-LF kuphela-yezinsiza eziphansi

 

• Ukuthi ama-fobs azobhalwa nguwe-kusayithi noma{1}}kufakwe ikhodi ngaphambili ngumkhiqizi

 

• Isampuli{0}}yangaphambilini yokukhiqiza ihlolwe kukhiya wangempela, isifundi, isifaki khodi nesofthiwe, hhayi ukulingisa kwebhentshi

 

• Emahhotela, ukuqinisekiswa ngokumelene nolayini wokukhiya ofakiwe ngaphambi kwevolumu; emahhovisi, ukuvalwa okuchaziwe kanye{0}}nenqubo yokukhishwa kabusha kwemininingwane elahlekile

 

Ukuqalisa lolo hlu futhi ukuhambisana kwe-rfid key fob kuyeka ukuba ukugembula futhi kuba ibhokisi lokuhlola: umaka wehhotela-uqinisekiswa ngokumelene ne-ecosystem yokukhiya, kuyilapho i-office fob iqinisekiswa ngokumelene nenkundla yokuphatha kanye nenqubo yokuqinisekisa{1}}yomjikelezo wokuphila. Uhlu lokuhlola olufanayo, ukugcizelela okuhlukile.

 

Kungani umkhiqizi ngemuva kwe-fob ebaluleke kakhulu kunentengo

 

Zontathu izindlela zokwehluleka zabelana ngomsuka owodwa: ziqala ekuhlanganiseni nasekubhaleni ngekhodi, izinyathelo ezimbili inkampani ehwebayo ikhipha imithombo futhi ayikwazi ukulawula ngokugcwele, kanye nalapho kuqala khona ukwehluleka okuningi. Thenga i-rfid key fob kumdayisi futhi lezo zinyathelo ezimbili zenzeka endaweni ongeke uyibone. Thenga embonini esebenzisa i-chip bonding kanye nombhalo wekhodi-endlini futhi bahlala ngaphakathi kwesistimu yekhwalithi.

 

Lokho kuyisimo sangempela sokuthola ama-fobs okhiye e-rfid angokwezifiso ngokuqondile kumkhiqizi esikhundleni sokuthengisa umkhiqizo okwesibili: lawula izinyathelo ezimbili ezinquma ukuthi izifakazelo ziyasebenza yini, ukuhlola okuphelele kokugcina kunokuhlola amabala, nezinga lokukhubazeka elingaphansi kwephesenti elilodwa emigqeni yevolumu ephezulu-. Ibonakala nasekuziphatheni okuphindayo futhi. Umbhalo wekhodi wethu nokuzinza kwemvamisa ukucindezelwa{3}}kuvivinywa izinhlelo ezihlela kabusha ngesilinganiso unyaka nonyaka: uhlelo lwebhange-lohlelo lwekhadi nge-oda lemininingwane eyizigidi ezimbili minyaka yonke, ukuzijabulisa{5}}okuhlanganisa izinkokhelo zepaki ezithatha ezinye izigidi ezimbili, futhi, ohlangothini olukhethekile, ibhilidi lesiFulentshi-lokuthola uchwepheshe{6}}lokufinyelela uchwepheshe{}}okuhlanganisa iminyaka eyi-8{7} ehlanganisa iminyaka eyisihlanu{7} izingcezu eziyizigidi ngonyaka. Ama-oda aphindayo kuleso sikali awubufakazi obuqotho bokuthi umbhalo wekhodi ubambelele ngokuhamba kwesikhathi, hhayi nje kuthreyi yesampula. Ngaphakathi kwemakethe ebanzi ye-RFID, ebiza cishe amabhiliyoni angu-US$15.6 ngo-2025 ngokubala kwe-IDTechEx, izifakazelo eziphakeme{13}}zemvamisa ezisetshenziselwa umyalo wokufinyelela okuvikelekile ziba phezulu{14}}ngeyunithi yomaka kunamathegi e-UHF alahlwayo ngokuqondile ngoba ukuphepha kuyiphuzu lonke. Leyo enye indlela yokusho ukuthi i-chip yilapho imali nobungozi kokubili kuhlala khona.

 

Uma uhlola ukugijima manje, lesi yisiteji laphoifekthri-i-RFID eqondile yokwenza i-key fobizuza ukugcinwa kwayo: isampula nokuhlola ukuhambisana kwenzeka ngaphambi kwevolumu, hhayi ngemva kwezikhalazo.
