Olonda Otya Ekyuma kya RFID?
Mu butuufu, ekibuuzo kino tukikoowa.
Tebakooye bakasitoma-okukoowa ekibuuzo kyennyini. Kubanga buli lwe tulina okubuuza ekibinja ky’ebibuuzo okuddayo: Olina okusoma okutuuka wa? Taagi egenda ku surface ki? Munda oba bweru? Ekyuma kyonna ekiri okumpi? Amazzi gonna? Embalirira yo eri etya? Oyagala obukuumi bwa clone?
Awatali mawulire gano, "ekyuma ki ekya RFID ekisinga obulungi" tekiddibwamu. Kiba ng'okubuuza "emmotoka ki esinga" nga togambye oba osuula abaana ku ssomero oba okusika emigugu cross-country.
Frequency-abantu abasinga kino bakifuna mu bukyamu okuva ku ntandikwa
Tubadde tukola okuva mu 2006. Tulabye pulojekiti nnyingi nnyo nga zifa olw'okulonda frequency.
Ekyokulabirako kya classic: kasitoma yali ayagala okulondoola yinvensulo ya sitoowa. Yawulidde UHF esoma wala, yagenda butereevu ku 860-960MHz. Kiki ekyabaddewo? Sitoowa ye yali ejjudde ebyokunywa eby’omu bucupa. UHF signal yafuna absorbed by water, read rates zaali kasasiro. Eno si nsonga ya mutindo-ye physics. Amazzi ne UHF tebitabula.
Flip side: tugabira FDX-B glass tube microchips eri kkampuni y’ebyobulamu by’ebisolo eya Turkey. Been working together for years kati, units ezisukka mu 300k buli mwaka. Lwaki tebakozesa UHF? Kubanga chips zigenda wansi w’olususu lw’ebisolo. 134.2kHz low frequency eyingira mu biological tissue. UHF tesobola. ISO 11784/11785 ebaddewo okumala emyaka mingi-si lwakuba nti waliwo eyagilonda mu ngeri ey'ekifuulannenge, wabula lwakuba nti frequency eno mu butuufu ekola ku mibiri emiramu.
13.56MHz high frequency ekwata kaadi z’okuyingira, okutambuza, okusasula. Soma ebanga ebiseera ebisinga wansi wa mita emu, mu butuufu nga kino kya bukuumi-toyagala muntu asoma badge yo ey'okuyingira okuva emitala wa paakingi.
Okulabula kw'ebyokwerinda
Naye obukuumi bwa frequency n’obukuumi bwa chip bintu bya njawulo. Mu 2008, abanoonyereza mu Radboud University Nijmegen baakutula ensirifu ya NXP eya Mifare Classic. Kaadi nga kawumbi ze zaakosebwa mu nsi yonna, nga muno mwe muli ne kaadi za London eza Oyster. NXP yagezezzaako okuzibira empapula; Kkooti ya Budaaki yategeezezza nti nedda. Kaadi empya zikozesa DESFire ne AES-128 kati, naye abasomi ab’edda bakyali buli wamu. Kale bakasitoma bwe baagala okufuga okuyingira, bulijjo tusooka kubuuza: protocol ki omusomi wo aliwo gy’awagira?
Form factor kikulu nnyo okusinga abantu bwe balowooza
Cards vs keyfobs-abantu abasinga balowooza nti ndabika yokka. Si bwe kiri.
Kaadi zigenda mu waleti. Wallet zirina kaadi za bbanka, endagamuntu ezizeetoolodde, ezimu zirina ebikwaso eby’ekyuma. User waves wallet ku reader, tewali kigenda mu maaso, akubira essimu okwemulugunya card emenyese. Kaadi temenyese-erina ngabo.
Ebisumuluzo biwanikiddwa ku bisumuluzo. Omukozesa agikwata butereevu ku musomi. Asoma buli mulundi.
Tukoze ne kampuni y'okuzaala badge y'okuyingira esangibwa mu Bufalansa- okumala emyaka etaano. Ebisumuluzo bya FUID nga 500k buli mwaka. Mu kusooka baali baagala kaadi. Ekyusiddwa oluvannyuma lw'okuyita okuwagira "kaadi tekola" kungi nnyo. Volume y’okwemulugunya yakendeera mangu. Era baatulina okukyusa ekibumbe nga tussaako akabonero kaabwe ak’enjawulo okutangira ebicupuli mu katale kaabwe. Ekika kino eky'okulongoosa-amakampuni g'obusuubuzi tegasobola kukikola. Tebalina bikuta, ebintu bya sitokisi byokka. Okwetaaga omukozi w’ebisumuluzo bya RFID yennyini ku nkyukakyuka mu bikozesebwa.
Ebikozesebwa nabyo bikulu. PVC ya buseere naye enjatika wansi w’okunyiga n’eddagala. Tulina kasitoma wa Portugal akola event management-obutambaala obusukka mu bukadde buli mwaka nga kwogasse ne cards 100k+. Bakola emikolo gy’ekiro, beetaaga okukuba ebitabo mu ngeri ya UV fluorescent eyaka wansi w’ettaala enzirugavu. Standard PVC printing tesobola kugikwata, yeetaaga enkola ey'enjawulo. Okwetaaga okw’ekika kino era kwetaaga ekkolero erikola enkola zaayo.
Obukuumi bwa chip-abantu abasinga tebalina kirowoozo kyonna
EM4100 esoma-chips zokka? Gula ekyuma ekikoppa ku Taobao ku ssente amakumi abiri, clone mu sikonda. Engasi y’okulondoola ebikozesebwa, okuddukanya engoye. Ku lw’okuyingira mu mulyango? Okusaaga. Tubadde ne bakasitoma abagamba nti "ekizimbe kyaffe eky'omuzigo kikozesa kino." Kye nsobola okwogera kiri nti obukuumi bw’ekizimbe kyo okusinga buba bwa katemba.
T5577 eddamu okuwandiikibwa, nnyangu okugezesa dev, naye obukuumi bubi nnyo okusinga EM4100 kubanga write barrier eri wansi.
Ku kufuga okuyingira, okusasula-ekitono kulina okuba ku ddaala lya Mifare DESFire. AES encryption, okukakasa buli omu. Buli chip egula ssente nnyingi, naye obukuumi bwa ddala.
Ebikwata ku kunoonya abagaba ebintu
Ekitundu kino kiwulikika nga self-serving, naye nja kukyogera anyway.
Amakolero ga RFID galina kkampuni z’obusuubuzi nnyingi nnyo. Bano bafuna okuva mu Factory A leero, Factory B enkya, ani asinga obuseere. Ekitundu kyo ekisooka n’ekyokubiri biyinza okuva mu makolero ag’enjawulo ddala. Okukwatagana kwa frequency, emiwendo gy'amakungula-tewali bukakafu.
Tukola chip bonding yaffe, antenna winding, injection molding. Layini ttaano ezikola ebintu, zonna mu kifo kyaffe e Hunan. Auburn University RFID Lab ebadde ekola satifikeeti ya ARC okuva mu 2009. Walmart, Costco zeetaaga ARC-tags ezikakasibwa-kubanga omutindo gw’amakolero gwawukana nnyo, omuntu yeetaaga okukakasa.
Kkampuni ya pulojekiti ya Tajikistan efuna kaadi za custom nga obukadde 2 okuva gye tuli buli mwaka olw’obuweereza bwa bbanka-emisolo, emisolo, eby’obulamu, 250+. Pulojekiti ku mutendera guno zirina obuvunaanyizibwa nga kaadi ziremye. Tebagenda ku source randomly okuva mu company esuubula.
Ekkolero lya RFID keyfob erifuga okukola kwalyo lisobola okukakasa obutakyukakyuka. Abasuubuzi tebasobola.
N’ekisembayo, ku bikwata ku nsaasaanya
Totunuulira bbeeyi ya yuniti yokka.
Bbeeyi ya tag entono naye omuwendo gw'okulemererwa omunene kitegeeza nti osindika abantu ku mikutu okubakyusa-eyo y'omuwendo omutuufu. Gula ebisomi ebya layisi, firmware updates teziziwagira oluvannyuma, ddamu ozikyuse, n’okusingawo. Middleware charging buli transaction, bills zifuna okutiisa once volume ramps.
Inditex bwe yafulumya RFID mu maduuka gonna aga Zara mu mwaka gwa 2016, Wall Street Journal yategeeza nti baagula chips obukadde 500. Pablo Isla yakiyise "emu ku nkyukakyuka ezisinga obukulu mu ngeri amaduuka gye gakola." Lwaki ssente ezo baazikozesa? Kubanga baabalirira omuwendo gwonna. Okufuna okulonda ekyuma mu ngeri entuufu kikekkereza ssente nnyingi wansi okusinga bwe kigula mu maaso.
Ensonga y’emu ekwata ku pulojekiti entonotono. Kifune bulungi, okusaabala obulungi. Kifune bubi, omutwe gulumwa emirembe gyonna.
Oyo ye take yaffe. Olina pulojekiti entongole gy’ogenda okukubaganyaako ebirowoozo?
