RFID Theme Park Wristbands: A Procurement Playbook yeKubudirira, Chengetedzo, uye Kushandisa Kwevaenzi

Nhamba nhatu dzinotsanangura kuti sei mapaki mazhinji achizoenda kune wristband{{0}based system. Vaenzi vanopedza chikamu chikuru chekushanya kwavo - nefungidziro yemubatanidzwa wemaindasitiri, ingangoita 60% - vakamira mumitsetse pane kukwira, kudya, kana kutenga. Pasi pemapepa-mabasa ematikiti, chikamu chevashanyi vanoshandura kuva mari ine revo yechipiri chinowanzogara pasi pe15%. Uye dhirowa rega rega remari, tikiti rakadhindwa, uye cheki yegedhi remanyorero inotakura mutengo wevashandi unokwira zvakananga nekupinda. Kubvinza kutatu uku - nguva, kushandisa, nekubata - ndicho chikonzero chaicho RFID theme park wristbands ichibva pautsva hwemutambo kuenda kune yakajairwa park infrastructure.

 

Izvo zvinotevera zvakanyorwa kubva kudivi remupi wetafura, asi kwete sepepa rekutengesa. Ndiyo pfungwa yekusarudza yatinofamba nayo vatengi vasati vaita hesiti yemwaka wakazara, kusanganisira zvikamu zvesarudzo zvinotarisa chinyararire kana kuburitswa kunobudirira.

 

 

Zvinotaurika nenhamba dzeDisney pakati-saizi park

 

Disney's MagicBand ndiyo yakanyanya-yakataurwa humbowo hweRFID theme park wristbands, uye mibairo yakanyorwa kwete anecdotal.Turnstile transaction time yakadzikira nechikamu chinosvika 30%, uye ruzivo rwekushanda kubva kubhendi data rinoita kuti mapaki asunda simba rinoshanda kusvika ku30% panguva yekuongorora kweHarvard.Harvard Bhizinesi Chikoro Dhijitari Initiative). Mugore rekutanga rakazara, mvumo yevaenzi yakapfuura 90% paine mabhendi anopfuura mamirioni gumi ari kushandiswa, uye kota mushure mekuburitswa yakaratidza kuwedzera kwepurofiti inosvika 20%, zvichikonzerwa nekuwanda kwe-kushandiswa kwepaki (World Economic Forum).

 

Hechino chikamu chakakosha mukati memunhu asati ataura nhamba idzo mumusangano webhajeti: Disney yakashandisa mari ingangosvika bhiriyoni remadhora kuti ivatore, vachivaka patsva zvivakwa zvepaki uye kushandisa -frequency architecture - pfupi{2}}HF/NFC yematepi, yakareba{3}}renji yeUHF yekutevera maredhiyo emudunhu kana kuti - kuedza kutevedzera mafambiro eredhiyo, pamwe nepakasiyana. Chidzidzo chepakati-chinofanirwa kutora mushandisi kubva kuDisney handicho tekinoroji stack. Ndiko kutevedzana: ivo vakaroverera kupinda uye kudhumhana kwekubhadhara kutanga, wobva warega iyo data inobatanidza. Paki inoedza kuvhura mashandisirwo emunhu uye analytics isati yatanga-kubhadhara{10}}yakavimbika ndeyekutenga chidzidzo chinodhura icho Disney atobhadharirwa.

 

Matanidza bhandi nekukwira, kwete bhurocha

 

 

Material ndipo panowanikwa mutengo wakachipa-unoshanduka kuita kukanganisa kunodhura zvakanyanya. Kune yakasimba RFID theme park wristband, sarudzo chaiyo inotarwa nekupfeka kwenguva uye kuratidzwa kwemvura, kwete nemutengo weyuniti, uye matatu anonyanya kuzivikanwa epaki anonongedzera kune mhinduro dzakasiyana.

Kune paki yemvura inoisa bhendi pamuenzi kwemaawa masere emasiraidhi uye masaisai madziva, isina mvura silicone ndiyo yega zvinhu zvinorarama zuva pasina kusunungura kana kushatisa. Paunenge wagadzikana pazvinhu, zvedusilicone RFID wristbands yakavakirwa mvura-kupfeka mupakiratidza-magiredhi ezvokudya uye mavharo anogadzirika anogara kusvika mwaka uzere.

 

Ipo sarudzo inopatsanurwa zvechokwadi ndipo pakati-tier: imwe mwaka-pass park inosarudza pakati peyakarukwa nesilicone iri chaizvo kusarudza pakati pemhando yemhando uye yakanyanya kukwidibira, uye tayi-inodambura kazhinji ndeyekuti bhendi rinoda kupetwa kaviri sechiyeuchidzo. Bandi rinochengetwa nevaenzi ibhendi rinotengesa paki kana vabva, ndosaka souvenir-magiredhi emidziyo ichiwanzoita kuti mari yacho ibhadharwe nenzira isina kuenzaniswa nemutengo.

The security gap vatengesi havatauri

 

Kana chirongwa chako chichizobata mubhadharo kana kuganhurirwa-nzvimbo yekuwana, verenga izvi usati wasaina chero chinhu. MIFARE Classic - ichiri kutengeswa nemudziyo-mutoro we "security" wristbands - inoshandisa Crypto-1 cipher yakaputswa nevatsvakurudzi vezvidzidzo makore apfuura; cheClassic credential inogona kuumbwa mukurwiswa kwekadhi chete nemaminetsi epadhuze kune chinangwa (IACR ePrint Archive).

Iyo chaiyo dhizaini ndiyo inoshanduka yakachipa makotesheni anovanza. Kutumirwa kwewristband yakachengeteka hakumbochengete magwaro chaiwo ekubhadhara kana kodzero yekuwana nyanzvi pabhendi pachayo - inochengeta tokeni kana UID, uye iyo account chaiyo inogara mune encrypted backend iyo inogona kudzimwa ipapo bhendi rikarasika.
