Ni irihe tandukaniro riri hagati ya RFID na NFC?

IMVURA RFID ikoresha sisitemu yo kubara Walmart. NFC ikoresha Apple Pay. Umuryango umwe wa tekinoroji ya radio umuryango, imirimo itandukanye.

 

 

Inganda zikoresha "IMVURA" kuri UHF RFID kuko "UHF Gen 2 EPC RFID" yari ndende cyane kubivuga. Impinj, Google, Smartrac na Intel batangije imbaraga zo kwamamaza mumyaka yashize, baguza mugitabo cya WiFi. Iyo tagi itwaye ikirango cyimvura, ikurikira ISO / IEC 18000 - 63 hamwe na GS1 EPC Gen2 protocole. EPCglobal yemeje verisiyo ya mbere ya Gen2 mu Kuboza 2004. Version 1.2.0 yaje mu mwaka wa 2008. Ibiriho ubu, Gen2v2, byatangiye mu 2013. Ivugurura rishya, Gen2v3, ryanyuze mu isuzuma ry’itsinda rya GS1 mu mpera za 2023 kandi byari biteganijwe ko ryemezwa mu ntangiriro za 2024. Megan Brewster wo muri Impinj yafatanije na komite ishinzwe iterambere.

 

NFC yicaye kuri megahertz 13.56. Hejuru - inshuro RFID ifata umurongo umwe. Itandukaniro: NFC yongeraho urungano - kuri - ubushobozi bwurungano. Ibikoresho bibiri bikora birashobora guhinduranya amakuru inyuma. Bisanzwe RFID ni umusomyi - ibiganiro - ubanza - tagi isubiza gusa iyo ibajijwe.

 

Muri Werurwe 2002, Sony na Philips Semiconductor bakoze ibisobanuro bya tekiniki.Ihuriro rya NFC ryinjijwe muri Werurwe 2004 hamwe na Nokia nk'umunyamuryango wa gatatu washinze. Philips yahagaritse igice cyayo cya kabiri nka NXP mu 2006. Terefone ya mbere y’ubucuruzi NFC, 6131 ya Nokia, yoherejwe muri uwo mwaka. Android yajyanye na Nexus S mu 2010. Apple yahagaritse kugeza iPhone 6 muri Nzeri 2014.

 

Urwego rutuma bagira akamaro kubintu bitandukanye. Ibiranga imvura birashobora gusomwa kuva muri metero. Basomyi buzura agace k’ingufu za RF kuri 860 kugeza kuri megahertz 960; tagi ya pasiporo isarura izo mbaraga kugirango imbaraga zabo zisubizwe. Ibirango bifatika bitwara bateri kandi byohereza kure. NFC igera kuri santimetero 4 - hafi bihagije kuburyo ugomba kubisobanura.

 

Kwimura umuvuduko ntabwo bihiganwa na Bluetooth. NFC igera kuri kilobits 424 ku isegonda. Bluetooth 2.1 yakubise megabits 2.1. Verisiyo ya 5 ikora byihuse. Ariko NFC ihuza munsi yicumi cyamasegonda idafite gahunda ikurikirana. Google yubatse Android Beam hafi yuburyo bworoshye. Bishe ibiranga nyuma.

 

Inshingano z'abatanga Walmart zaragutse kuva muri 2020.Imyambaro yaje ku mwanya wa mbere. Ibicuruzwa byo mu rugo, ibikinisho, ibikoresho bya elegitoroniki, ibicuruzwa bya siporo byakurikijwe mu 2022.Icyiciro rusange cy’ibicuruzwa rusange cyatangiye kugeza mu 2024. Tagi ikoresha amafaranga 4 kugeza kuri 6 buri umwe. Mu myaka ya za 2000 rwagati, igihe Walmart yagerageje gusunika RFID mbere, baguze amafaranga 30 kandi bafite igipimo cyo gutsindwa kiri hejuru kuburyo abatanga ibicuruzwa bagiye.

 

Kwishyura kwishura kwishura biragoye gukurikirana. NFC ikora inyuma. Ukanda, birishyuza. Visa, Mastercard na Amex bubatse ibikorwa remezo bidafite aho bihurira hafi ya ISO / IEC 14443, ikarita yerekana ikarita yegeranye ihura na NFC kurwego rwa megahertz 13.56. Ihuriro rya NFC risobanura 14443 hanyuma wongere porogaramu - urwego protocole nka NDEF yo guhuza amakuru.

 

Uburyo bwo gusoma buratandukanye. Antenna yumusomyi wa RFID irashobora gutondekanya amagana mumasegonda make - ingirakamaro kubara kubizunguruka mububiko cyangwa mububiko. NFC ikora icyarimwe icyarimwe. Iyo mbogamizi ihuza imirongo yo kugenzura ariko yagabanya umuvuduko wo kugabura.
