I-RFID Theme Park Wristbands: Incwadi yokudlala yokuFumana ngokuSebenzayo, uKhuseleko, kunye neNkcitho yeeNdwendwe

Amanani amathathu achaza ukuba kutheni iipaki ezininzi ekugqibeleni zifudukela kwi-wristband{{0}esekelwe kwinkqubo. Iindwendwe zichitha isixa esikhulu sotyelelo lwazo - ngoqikelelo lombutho weshishini, kufutshane ne-60% - emi emigceni kunokukhwela, ukutya, okanye ukuthenga. Ngaphantsi kwephepha-imisebenzi yamatikiti, inxalenye yabatyeleli abaguqulela kwinkcitho enentsingiselo yesibini ihlala ingaphantsi kwe-15%. Kwaye yonke idrowa yemali, itikiti eliprintwe ngokutsha, kunye nokutshekishwa kwesango ngesandla kuneendleko zabasebenzi ezinyuka ngokuthe ngqo kunye nokuzimasa. Ezo zintathu zivuzayo - ixesha, ukuchitha, kunye nokuphatha - sesona sizathu se-RFID somxholo wepaki amabhanti asusiweyo kumnyhadala omtsha ukuya kwisiseko sepaki esiqhelekileyo.

 

Oku kulandelayo kubhalwe kwicala lomthengisi wetafile, kodwa hayi njengephepha lokuthengisa. Yingcinga yokukhetha esihamba ngayo abathengi phambi kokuba benze uluhlu lwempahla yexesha elipheleleyo, kuquka namacandelo esigqibo amisela ngokuzolileyo ukuba ukukhutshwa kuyaphumelela.

 

 

Yintoni amanani kaDisney ayixelayo phakathi-ubungakanani bepaki

 

I-Disney's MagicBand yeyona ndawo yobungqina be-RFID ekhankanyiweyo kwi-Wristbands yepaki yomxholo, kwaye iziphumo zibhalwe endaweni ye-anecdotal.Turnstile transaction time yehle malunga ne-30%, kunye nokuqonda kokusebenza okuvela kwidatha yebhendi kuvumela iipaki zityhale amandla asebenzayo phezulu kangange-30% ngexesha lenkqubo yeHarvard.Inyathelo leDijithali yeSikole soShishino saseHarvard). Kunyaka ogcweleyo wokuqala, imvume yeendwendwe iqhube ngaphezulu kwe-90% kusetyenziso olungaphezulu kwezigidi ezilishumi zamabhanti, kwaye ikota emva kokukhutshwa ibonise ukonyuka kwengeniso emalunga ne-20%, kubalelwa kuphezulu{3}}inkcitho epakini (IForam yezoQoqosho yeHlabathi).

 

Nali icandelo elifanele ukwenziwa ngaphakathi phambi kokuba nabani na acaphule loo manani kwintlanganiso yohlahlo lwabiwo-mali: UDisney uchithe malunga nebhiliyoni yeedola ukuwafumana, esakha kwakhona isiseko sepaki kunye nokusebenzisa -ulwakhiwo oluphindaphindayo - olufutshane{2}}uluhlu lwe-HF/NFC lweempompo, ubude{3}}uluhlu lwe-UHF lokulandela umkhondo werediyo okanye {4} kufuneka ikhuphele intshukumo yerediyo okanye ipaki. Isifundo esithathwa ngumsebenzisi ophakathi{6} kwi-Disney ayisositaki sobuchwepheshe. Lulandelelwano: babethelela ufikelelo kunye nengxabano yentlawulo kuqala, emva koko bavumele i-compound yedatha. Ipaki ezama ukuphehlelela ulungelelwaniso kunye nohlalutyo phambi kokuba itephu yayo esisiseko{9}}ukuhlawula{10} ithembekile ithenga isifundo esiduru esihlawulwe nguDisney.

 

Tshatisa ibhendi nokukhwela, hayi incwadana

 

 

Isixhobo kulapho eyona mpazamo{0}}ekhangelekayo ijika ibe yeyona mpazamo ibiza kakhulu. Kwi-wristband yepaki ye-RFID ehlala ihleli, ukhetho olufanelekileyo luchazwa kukunxitywa kwexesha kunye nokuvezwa kwamanzi, kungekhona ngexabiso leyunithi, kwaye iimeko ezintathu eziqhelekileyo zepaki zikhomba kwiimpendulo ezahlukeneyo ngokwenene.

 

Imeko	Izinto ezicetyiswayo	Ngoba
Ipaki yamanzi,-intsuku ezininzi, ukuba sesichengeni samanzi aphezulu	Silicone	Ingangeni manzi ngokupheleleyo,{0}}iyaxhathisa, ikhululekile kuyo yonke{1}impahla yemini, iyaphinda isetyenziswe ngamaxesha onyaka
Ixesha lonyaka/lonyaka, ukusetyenziswa kwexesha elide{0}}okuphindaphindiweyo	Ilaphu eliphothiweyo okanye i-silicone	Ukuhlala ixesha elide kwiinyanga, ibrandable, ikhululekile ngokwaneleyo ukuba iindwendwe zihlala zinxibe
Isiganeko sosuku olunye-, ukusebenzisa{1}}kanye ukungena	Tyvek okanye PVC	Ixabiso eliphantsi, i-tamper{0}}iyabonakala, iyalahlwa ngaphandle kweenkxalabo zenkunkuma

 

Kwipaki yamanzi ebeka ibhanti kwiindwendwe iiyure ezisibhozo zeslayidi kunye namachibi amaza, i-silicone engangeni manzi yeyona nto iphilayo imini ngaphandle kokukhulula okanye ukuthotywa. Xa uzinzile kwizinto eziphathekayo, wethuiibhanti ze-silicone ze-RFID ezakhelwe ukunxitywa kwamanzi-epakinibonisa ukutya-ukhetho lodidi kunye nokuvalwa okuhlengahlengiswayo okubamba ixesha elipheleleyo.

 

Apho isigqibo ngenene sisesiphakathini -senqanaba: ipaki yexesha-lokudlula elikhetha phakathi kolukiweyo kunye nesilicone ikhetha ngokwenene phakathi kwenkangeleko yebhrendi kunye nobukhulu bobunzima, kwaye iqhina{2}}lophula iqhelekile ukuba ibhanti ifuna ukuphinda kabini njengesikhumbuzo. Ibhendi egcinwe ziindwendwe liqela elithengisa ipaki emva kokuba bemkile, yiyo loo nto isikhumbuzo{4}}izixhobo zebakala zihlala zithethelela iprimiyamu yazo ngeendlela uthelekiso lweendleko ekrwada luphosakele.

 

Ngomnyhadala{{0}wosuku olunye okanye{1}}isiganeko esisodwa sokwamkelwa, izibalo zijikela kwizinto ezinokulahlwa. I-Tyvek ifanelana nokunxiba okukodwa ngexabiso eliphantsi, ngelixa aIbhanti yePVC yokungeniswa epakini yosuku olunye-ithenga i-tamper-ubungqina kunye nokuqina ngakumbi xa imini ibaleka ixesha elide okanye imanzi - inqaku kukudibanisa nenkcitho kubomi bobomi, ungagqithisi{2}}ubunjineli beqela ozakulisika xa uvala.

 

Itshiphu-kunye{1}}nesigqibo sesiqhelo uninzi lwabathengi luyaphazama

 

Itshiphu imisela ukhuseleko, inkumbulo, ukufundeka kwefowuni{0}}, kunye nobomi; I-frequency igqiba ukuba ibhendi inokwenza ntoni na ngokwasemzimbeni esangweni xa ithelekiswa nombindi wendlela.

 

Itshiphu	Imemori enokusetyenziswa	Ukuma kokhuseleko	Eyona nto ifanelekileyo epakini
NTAG213	Iibhayithi ezili-144	Esisiseko (i-UID, igama lokutshixa)	Ukungena/ufikelelo, unxibelelwano lwentengiso, ifowuni{0}}iyafundeka; ixabiso eliphantsi
NTAG215/216	504 / 888 bytes	Isiseko	Utyebile kwi{{0}idatha yebhendi, unxibelelwano lweapp

Imithetho emibini esebenzayo iyaphuma kule nto. Okokuqala, i-125 kHz esezantsi{2}}iibhendi zefrikhwensi azinandawo kwindawo yokusasazwa kwepaki - zenziwe zakhiwe kancinci kwaye azithwali luguqulelo oluntsonkothileyo, kwaye esona sizathu sokuzichukumisa ngumfundi welifa obambene naye ngokwesivumelwano. Okwesibini, i-HF/NFC kunye ne-UHF aziyiyo enye/okanye; kwipaki eyilwe kakuhle-eyayilwe kakuhle bawahlulahlule umsebenzi, nge 13.56 MHz ebamba ivalelo{7}}uluhlu lwempompo yentlawulo kunye nolawulo lofikelelo esangweni, kunye ne-UHF ephethe -uluhlu olude lufundeka oko kuluhlu lwesondlo kunye nohlalutyo lwesihlwele.Ukuba umboneleli utyhala ifrikhwensi enye kuwo wonke umsebenzi, hayi ukwenza lula umsebenzi wabo, balungisa umsebenzi wabo. Sigcina ii-mechanics ezisisiseko kwireferensi eyahlukileyo ukuze esi siqwenga sihlale kwisigqibo sokuthengwa kwempahla - inguqulelo emfutshane kukuba ukuthelekisa amaza okusebenza yinto eyohlula inkqubo eyenza isikali ukusuka kwenye ekhutshiweyo kunyaka wesibini. (Kwizinto ezisisiseko, yethuisikhokelo RFID frequencies kunye neentlobo chipiyayichitha.)

 

Idatha ye-Chip{0}}ugcino lukwabalulekile ngokuzolileyo kwipass{1}esekwe kwiipaki. Kuxhomekeka kusapho lwechip, ugcino lwedatha olulinganisiweyo lusukela malunga neshumi leminyaka kwiNTAG kunye neMIFARE Classic iinxalenye ukuya kumashumi amabini{3}}iminyaka emihlanu okanye ngaphezulu kwizizukulwana ezifihliweyo zeDESFire - ezingabalulekanga kwibhendi yosuku olunye, isigqibo seminyaka emihlanu{6}yesiqinisekiso sonyaka{7}.

 

Ukhuseleko gap abathengisi musa ukukhankanya

 

Ukuba inkqubo yakho iyakuze ichukumise intlawulo okanye ithintelwe{0}}ufikelelo lwendawo, funda oku phambi kokuba utyikitye nantoni na. I-MIFARE Classic - isathengiswa ngesikhongozeli{3}}umthwalo "wokukhusela" iintambo zesihlahla - iqhuba i-Crypto yomnini{6}}1 i-cipher eyaphulwa ngabaphandi bezemfundo kwiminyaka eyadlulayo; inkcaso yeClassic inokuqulunqwa kuhlaselo lwekhadi kuphela ngemizuzu nje ekufutshane kwithagethi (I-IACR ePrint egciniweyo). Kwaye iye yaba mandundu mva nje: iqhosha elingasemva elifunyenwe kwi-Classic esetyenziswa ngokubanzi{1}}isizukulwana setshiphu esihambelanayo sivumela umhlaseli abe brute{2}}anyanzelise kwaye enze amakhadi athile malunga nemizuzu emibini (Ijenali yeRFID).

 

Ulwakhiwo oluchanekileyo lolona luguquguqukayo lwezicaphulo ezingabizi kakhulu zifihla. Ubeko olukhuselekileyo lwewristband aluze lugcine iziqinisekiso zentlawulo yokwenyani okanye amalungelo ofikelelo olukhulu kwiqela ngokwalo - ligcina uphawu okanye i-UID, kwaye i-akhawunti yokwenyani ihlala kwi-backend efihliweyo enokuvalwa ngoko nangoko ibhendi ilahlekile. Yenza loo nto, kwaye neqela elihlanganisiweyo alinaxabiso. Tsiba olo lwakhiwo ukugcina iisenti ezimbalwa kwitshiphu nganye, kwaye umfundi we-$300 kuphela ofunekayo ukukhupha ithebhu yomnye umntu.

 

Apho ukusasazwa ngenene kuya emacaleni

 

Ukucinga ukuba ibhendi kunye netshiphu zilungile, ukusilela okushiyekileyo kukungaphumeleli kohlanganiso - kwaye ukuba ucinezela kuphela -vavanya into enye phambi kokwamkelwa, yenze ifundeke uluhlu. Kukusilela okuvavanya kakuhle ebhentshini kwaye kuphoxeke kwisango elimanzi, elixineneyo, lesinyithi{3}}elibiyelweyo, kuba umgama wokufunda wokwenyani{4}uxhomekeke ekulungiseni i-eriyali kunye nokusingqongileyo kunomfanekiso ofanelekileyo wedatha - kwaye yeyona ivele yamva nje kwaye ixabisa kakhulu ukuphinda isebenze xa iibhendi sele zishicilelwe. Ukusilela kwesibini kukungahambelani nePOS ekhoyo kunye ne-turnstile stack; iqela elingakwaziyo ukuthetha nabafundi osele unabo luluhlu lwempahla, ayisosisombululo. Okwesithathu luqoqosho lobuxoki lweyona sicatshulwa sisezantsi, apho i-encapsulation ebhityileyo ithetha iibhanti eziqhekeka okanye ezingaphumeleliyo kwi-QC phakathi{8}}kwixesha lonyaka.

 

Nditsho nokusungulwa kukaDisney eyakhe kuyafundisa apha njengebali lokulumkisa endaweni yokuqaqambisa ireli: iibhendi zakuqala bezimfiliba, zifuna ukutshajwa ebusuku, kwaye zibaleka ngebhetri yeeyure ezisibhozo, kwaye inkqubo ithathe iindleko zokwenyani kunye nophindaphindo phambi kokuba isebenze. Into ethathwayo yomthengi echaza iibhanti zesandla zeRFID ezinomtsalane kukuba "faka kwaye ulibale" yintsomi - isampuli yokwakha, uvavanyo lokuhambelana nomfundi, kunye nomgangatho we-QC ekuthengeni, hayi kwisithuba{4}}esifayo.

 

Ukukhangela umthengisi phambi kokuba wenze uluhlu lwempahla yexesha lonyaka

 

 

Ngeli nqanaba indlela yokukhetha ithe cwaka isuka "kweliphi iqela" ukuya "kweliphi iqabane," kuba yonke into engentla - yechip integrity, umgangatho we-encapsulation, frequency matching, backend architecture - yimveliso{2}}kunye{3}}nombuzo wohlanganiso. Iintambo zethu zezandla ziqhubela kwi-isitofu sendlu kunye nemigca ye-eriyali ngokuchaneka kokungunda okubanjwe ukuya ku-±0.02 mm kunye nokuchaneka okujikelezayo ukuya ku-±0.1 mm, kwaye yonke iyunithi idlula i-100% yokuhlolwa kwefektri kwi-frequency, umgama wokufunda, kunye nokuthembeka kwedatha ngaphambi kokuba ithumele - umahluko phakathi kwebhendi efundeka kwaye ifundeka ekuqaleni} umgca, hayi kwiphepha ledatha. Olo lawulo luvela kwiminyaka engamashumi amabini yokwakhiwa kweemveliso zeRFID endlwini ukusukela ngo-2006, ezithunyelwa ngaphandle ukusukela ngo-2012, phantsi kwe-CE, ISO 9001:2015, kunye nesiqinisekiso se-ICAR - uhlobo lwerekhodi eliqinisekisiweyo elibalulekileyo xa uluhlu lwempahla lwexesha lukhwela kwi-odolo yokuthenga enye.

 

Olo lawulo lwemveliso lulo oluvumela umthengisi ukuba enze into enokuthi{0}}ibeke emngciphekweni iodolo yakho: isampuli ngokuchasene nabafundi bakho bokwenyani phambi kokuba ulinganise. Nawuphi na umzi-mveliso unokushicilela uphawu; bambalwa kakhulu abanokuqinisekisa ukusebenza ngokufunda ngokuchasene namasango akho kwaye bacebise itshiphu ehambelana neemfuno zakho zokhuseleko kune-inventri yazo. Kubasebenzisi abachaza inkqubo ngoku, eyona ndlela ikhawulezayo yokususa{3}}umngcipheko kukuvavanya iisampulu zomzimba ngokuchasene nenkqubo yakho phambi kokuba wenze -isiko RFID iinketho wristband ukuba iipaki kunye ezinomtsalanegubungela imathiriyeli epheleleyo kunye noluhlu lwetshiphu, kunye neiintambo ezilukiweyo ze-RFID ezakhelwe ngokukodwa ukonwabisa{{0}ukunxitywa kwepakizisiqalo esixhaphakileyo sexesha-lokusetyenziswa ixesha elide. Sixelele ukusetwa kwesango lakho kwaye siza kuyenza isampuli ngokuchasene nalo - iisampulu zasimahla zikuvumela ukuba uqinisekise uluhlu lokufunda kunye nokuqina kumasango akho phambi kokuba kuveliswe isambuku esinye.
