Indlela Yokukhetha OkulungileRFID Wristbands?
Siyekile ukucaphuna ama-chips e-MIFARE Classic kumaphrojekthi okulawula ukufinyelela cishe eminyakeni emithathu edlule. Ukubethela kwaphulwa emuva ngo-2008 futhi izinsiza zokuhlanganisa manje zibiza cishe amarandi angamashumi amahlanu ku-inthanethi. Amakhasimende ayelokhu ebuza ukuthi kungani singeke simatanise amanani esiqhudelana nawo kuma-Wristbands asuselwa ku-Classic{3}, futhi impendulo eqotho kwaba isibopho sezomthetho. Uma igumbi lesivakashi sendawo yokuvakasha liba sengozini ngenxa yokuthi othile wenze ibhande lakhe esihlakaleni endaweni yokupaka, leyo ngxoxo nezomthetho iba yimbi ngokushesha.
Lowo mbuzo wezokuphepha uhlala enkabeni yezinqumo eziningi zokukhetha i-wristband, kodwa amaqembu okuthenga awavamisile ukuqala lapho. I-RFQ evamile esiyitholayo ihola enamanani eyunithi kanye ne-MOQ. Lezo zibalulekile, ngokusobala, kepha zingamaguquguqukayo angezansi. Izinqumo ezikhuphukayo-ibhendi yefrikhwensi, umndeni we-chip, ukwakhiwa kwezinto{4}}zikhiya izindleko zakho zokuphakela eziphelele futhi zinqume ukuthi ingabe uhlelo lusebenza ngempela endaweni yakho ethile.
Imvamisa Inquma Izindleko Zengqalasizinda
Amabhande asesihlakaleni e-UHF abukeka ekhanga amanani evolumu. Izindleko zeyunithi zehla ziye ku-$0.05-0.25 ububanzi ngamanani ayizigidi nangaphezulu, okuphumayo kudlula omaka abangu-600 ngesekhondi, ibanga elifundwayo lifinyelela kumamitha angu-6-12 ngezifundi ezigxilile. Ishidi lokucaciswa lizithengisa lona.
I-physics iba nzima emizimbeni yabantu. Izimpawu ze-UHF azisebenzi kahle eduze namanzi, futhi cishe singama-60% amanzi ngobuningi. Ukuxhumana okuqondile kwesikhumba ngaphandle kokushiya isikhala kubangela ukwehluleka ukufunda okungabonisi kuze kube yilapho kuthunyelwa inkambu. Sifunde lokhu ngendlela ebizayo kuphrojekthi yepaki yamanzi ekwakhiweni kwesistimu ye-UHF enhle ka-2019, ingqalasizinda yokufunda eqinile, amabhande asesihlakaleni asebenza kahle ebhentshini lokuhlola futhi ahluleka ngezikhathi ezithile ezivakashini zangempela. Kugcine ukubuyisela kabusha ama-spacers amagwebu ekwakhiweni kwebhendi. Izingxoxo zeforamu ye-Arduino zibhala into efanayo ngokuphindaphindiwe; umdidiyeli oyedwa uphawule ukuthi noma iyiphi indawo eqhubayo eduze kwe-antenna ingakwazi ukuyikhipha ngokuphelele (forum.arduino.cc).
| Ukucaciswa | I-LF (125-134 kHz) | I-HF (13.56 MHz) | I-UHF (860-960 MHz) |
|---|---|---|---|
| Funda Ibanga | Ngaphansi kuka-10 cm | Cishe 1 m | 6-12 m umfundi ogxilile |

Ukuthuthukiswa kwe-MagicBand ye-Disney-ibhiliyoni{3}}lokutshalwa kwe-dollar{3}}ngokuya ngokubika komkhakha{4}}kuhambe i-HF/NFC ngokuqondile ngokwethembeka ekugqokeni kwezivakashi okuqhubekayo (gocanopy.com). Ukuvumelana kwebhendi ye-Global ISM kuqeda ukuvela kwelayisensi. Ama-Smartphones afunda i-NFC ngokomdabu.
I-LF isekhona ekulawuleni ukufinyelela kwefa. Siyayicaphuna uma amaklayenti enengqalasizinda ekhona angakwazi ukuyishintsha, kodwa ukuthunyelwa okusha akuvamile ukukuthethelela.
Ukunikezwa kwamafrikhwensi kwesifunda kudala izinkinga zokuthumela ngaphandle kwemikhiqizo ye-UHF. I-spectrum yase-US isebenzisa i-902-928 MHz, i-EU isebenza ngo-865-868 MHz emikhawulweni yamandla ephansi, i-Japan isebenzisa i-952-954 MHz. I-wristband elungiselelwe ukusetshenziswa eNyakatho Melika ingase ingasebenzi ngokusemthethweni noma ngempumelelo ezindaweni zase-Europe.
Ukukhetha Okubalulekile
I-Silicone
Ukwakhiwa kwe-silicone kusebenzisa ukucindezelwa kokubumba nge-RFID yokushumeka inlay ngesikhathi sesiteji sokubumba ngokwaso. I-encapsulation ephelele ifinyelela isilinganiso se-IP68-ukucwiliswa ngaphansi kwamanzi okuqhubekayo, ukubekezelela izinga lokushisa ukusuka -ku-40℃ukuya ku-+85℃. Izithako zezinga lezokwelapha zikhona ukuze zigqokwe isikhathi eside isiguli. Amathuluzi angokwezifiso engeza izinsuku zebhizinisi ezingu-7-10 ekukhiqizeni kokuqala kodwa kunika amandla ukulawula okunembayo kobukhulu.
Indwangu
Amabhande asezihlakaleni endwangu enza isemishi imojula ye-chip phakathi kwezingqimba ze-polyester ezilukiweyo. Basingatha{1}}izinsuku eziningi zokujuluka kanye nokuchayeka emvuleni, yingakho amafestivali aba sezingeni kuzo. Umbala-ogcwele wokufaka uphawu ngokudlulisa okushisayo endaweni yonke.
I-Tyvek
I-Tyvek isebenzisa u-$0.03-0.10 ngeyunithi ngayinye ngevolumu. Ukumelana ne-splash, hhayi ukufakazela ukucwiliswa emanzini. Imicimbi-yosuku olulodwa lapho izindleko-zomuntu ngamunye ohambele umcimbi zingaphezu kwesinqumo lapha. Sithumele amabhendi e-Tyvek ezinkulungwane ezimbalwa zeklayenti lenkomfa ngonyaka odlule elalidinga ukulawula kokufinyelela okuyisisekelo ngaphandle kwezinsimbi namakhwela. Isebenza kahle ekusetshenzisweni kwabo.
I-PVC
I-PVC ihlala phakathi nendawo: ingangeni manzi, 2-ukuqina kwezinsuku ezingu-7, ifanele amapaki amanzi lapho intengo ye-silicone kunzima ukuyithethelela uma kuqhathaniswa nezomnotho zokuvakasha kanye.
I-Chip Security Ibaluleke Kakhulu Kunokuba Abathengi Abaningi Baqaphela
I-MIFARE Classic isabusa izicelo zekhotheshini ngoba ishibhile futhi ijwayelekile. Ukubethela kwe-CRYPTO1 ngokhiye abangama-48-bit. Yaphulwa esidlangalaleni eminyakeni eyishumi nanhlanu edlule. Ukuhlaziywa kwemboni kuqondile mayelana nemithelela: amasistimu athembele ku-Classic ukuze alawule ukuphepha anobungozi be-cloning (rfidcard.com).
Kunoma yini ehlanganisa imininingwane yokukhokha, isitoreji sedatha yomuntu siqu, noma ukulawula ukufinyelela okuphathekayo, sicacisa ubuncane be-DESFire EV2/EV3. Ukubethela kwe-AES-128, izinga lamanje lokuvikeleka. Iprimiyamu ye-chip ngayinye isebenzisa amasenti ayishumi nanhlanu kuya kwangamashumi amathathu kune-Classic. Amaklayenti okunakekelwa kwezempilo aya ngokuya adinga i-AES-128 noma i-AES-256 yemibhalo yokuthobela i-HIPAA.

I-Deployment Economics
I-MOQ ishintshashintsha kakhulu. Amabhande esandla ajwayelekile ajwayelekile adinga ubuncane beyunithi engu-500-1,000. Indwangu ngokuvamile iqala ku-300. Ama-chips akhethekile angase adinge ukuzibophezela okukhulu. Amanani amasampula abashayeli bezindiza adinga ukuxoxisana okucacile kodwa izindawo eziningi zokukhiqiza zivumela ukugijima okuncane.
Ingqalasizinda yokufunda imele amaqembu okuthenga esigaba sezindleko ahlale ebukela phansi. Izifundi ezigxilile ze-UHF zisebenzisa u-$1,000-2,000 endaweni ngayinye yokufaka. Amamojula e-HF/NFC abiza cishe u-$300 lilinye. Ilayisense ye-Middleware iqala kusukela kuzinketho zomthombo ovulekile kuya ezinkundleni zebhizinisi emashumini ezinkulungwane ngonyaka.
Amazinga okungasebenzi kahle okukhiqiza ama-inlay e-RFID afinyelela ku-20% ekukhiqizeni. Umehluko phakathi kwabahlinzeki ubonakala kumaphrothokholi okuhlola. Izinsiza ezihlola ukuhlolwa okungu-100% kokunamathiselwe kwe-IC, okuthunyelwe{4}}ukuguqulwa, kanye{5}}nokunamaphutha okubanjwa kokwenza kube ngokwakho ngaphambi kokuthunyelwa. Izinsiza zokuthumela amasampula ezibalo ziphusha ukutholakala kokukhubazeka kusayithi lakho lokuphakelwa. Sithathe izingcingo eziphuthumayo ezivela emaqenjini emicimbi ngobusuku bangaphambi kokuvula iminyango, ukuxazulula inkinga kufundeka ukwehluleka okubuyela emuva kumaqoqwana amabi umphakeli angakaze abanjwe.
Lokho Ukuthunyelwa Okuphumelele Okufana Ngayo
I-Jacobi Medical Center ilinganise ukonga kwesikhathi somhlengikazi cishe ihora ngokushintshashintsha ngemva kokukhipha amabhande asesihlakaleni angu-13.56 MHz ukuze kuhlonzwe isiguli, kwabikezela izigidi{1}}zemali yokonga yonyaka esikalini senethiwekhi (pdchealthcare.com). I-Cambridge University Hospitals ilandelele i-RFID emibhedeni eyinkulungwane kanye nama-37,500+ ukucwaningwa kwamadivayisi{6}}kwehle kusukela emahoreni angu-1.5 kwaya kumaminithi angu-8.
Amabhendi e-RFID endwangu ye-Coachella acubungula abantu abangaba yinkulungwane ngomzuzu emasangweni okungena. Isici esimelene{1}nomgunyathi sehlise inkinga yabo yokungena ewumgunyathi isuka ku-105,000 yaya kwabangu-90,000 abalawulayo. I-Tomorrowland ibhale ngo-30% ngaphezulu{8}}ekusetshenzisweni kwesayithi ngokuhlanganiswa kokukhokha okungenamali (tappit.com).
Isibhedlela i-Providence Mission sibone ukulahleka kwemishini kwehla kusuka ku-14% kuya kuqanda, izindleko zokuqasha zehla zisuka ku-$20,{2}} nyanga zonke zaya ku-$1,000,-zonga zonyaka wokuqala zidlula u-$600,000.
Isici esingaguquki kukho konke lokhu: izidingo zobuchwepheshe zacaciswa ngaphambi kokuba kuqale ukukhethwa komhlinzeki.
Indlela Yokuhlola
Imvelo idonsa izithiyo. Ibanga lokushisa, ukuchayeka emanzini, ukuhlanza amakhemikhali, insimbi endaweni efundwayo{1}}ngakunye incisha izinketho ezisebenzayo ngaphambi kokuba kuqale izingxoxo zentengo. Ibanga lokufunda kanye nezidingo zokuphuma zinquma imvamisa. Izimfuneko zokuphepha zibeka i-chip floor. Umjikelezo wokuphila olindelwe uthinta umnotho wezinto ezibonakalayo.
