Pehea e koho ai i kahi mea RFID?
ʻOiaʻiʻo, luhi mākou i kēia nīnau.
ʻAʻole luhi i nā mea kūʻai aku- luhi i ka nīnau ponoʻī. No ka mea i kēlā me kēia manawa e nīnau mākou i nā nīnau he nui: Pehea ka lōʻihi e pono ai ʻoe e heluhelu? He aha ka ʻili o ka hōʻailona? Ma loko a ma waho paha? He metala ma kahi kokoke? He wai wai? He aha kāu kālā? Pono ʻoe i ka pale clone?
Me ka ʻole o kēia ʻike, "ʻo wai ka mea RFID maikaʻi loa" ʻaʻole hiki ke pane ʻia. Me he mea lā e nīnau "ʻo ke kaʻa ʻoi aku ka maikaʻi" me ka ʻōlelo ʻole inā e haʻalele ana ʻoe i nā keiki i ke kula a i ʻole ke kau ʻana i ke kaʻa kaʻa -'āina.
'O ka pinepine-ka hapa nui o ka po'e i hewa mai ka ho'omaka
Ua hana mākou mai ka makahiki 2006. Ua ʻike ʻia ka nui o nā papahana i make ma muli o ke koho alapine.
Ka laʻana maʻamau: makemake ka mea kūʻai aku i ka ʻimi waihona waihona. Lohe i ka UHF heluhelu mamao, hele pololei no 860-960MHz. He aha i hana ai? Ua piha kona hale waihona i nā ʻōmole inu. Ua komo ka hōʻailona UHF i ka wai, he ʻōpala ka helu heluhelu. ʻAʻole kēia he pilikia maikaʻi - ʻo ka physics. ʻAʻole hui ka wai a me ka UHF.
ʻaoʻao ʻaoʻao: hāʻawi mākou i nā microchips paipu aniani FDX -B i kahi hui ola holoholona Tureke. Ke hana pū nei no nā makahiki i kēia manawa, ʻoi aku ma mua o 300k mau ʻāpana i kēlā me kēia makahiki. No ke aha ʻaʻole lākou e hoʻohana i ka UHF? No ka mea, komo nā ʻōpala ma lalo o ka ʻili holoholona . 134.2kHz haʻahaʻa haʻahaʻa komo i loko o ke kino olaola. ʻAʻole hiki iā UHF. Ua ola ʻo ISO 11784/11785 no nā ʻumi makahiki-ʻaʻole no ka mea i koho wale ʻia e kekahi, akā no ka hana maoli ʻana o kēia alapine i nā kino ola.
ʻO ka 13.56MHz kiʻekiʻe e mālama i nā kāleka komo, transit, uku. Heluhelu maʻamau ma lalo o hoʻokahi mika, ʻo ia ka hiʻona palekana-ʻaʻole ʻoe makemake e heluhelu kekahi i kāu hōʻailona komo mai kēlā ʻaoʻao o kahi kahua kaʻa.
Hoʻolaha palekana
Akā ʻokoʻa nā mea ʻokoʻa ka palekana pinepine a me ka palekana chip. I ka makahiki 2008, ua haki nā mea noiʻi ma ke Kulanui ʻo Radboud Nijmegen i kā NXP's Mifare Classic encryption. Ma kahi o hoʻokahi piliona kāleka i hoʻopilikia ʻia ma ka honua holoʻokoʻa, me nā kāleka Oyster o London. Ua ho'āʻo ʻo NXP e ālai i ka pepa; Ua ʻōlelo ka ʻaha Holani ʻaʻole. Hoʻohana nā kāleka hou iā DESFire me AES-128 i kēia manawa, akā aia nā mea heluhelu hoʻoilina ma nā wahi āpau. No laila ke makemake nā mea kūʻai aku i ka mana komo, nīnau mua mākou: he aha ka protocol e kākoʻo ai kāu mea heluhelu?
ʻOi aku ka mea nui ma mua o ka manaʻo o ka poʻe
Kāleka vs keyfobs-manaʻo ka nui o ka poʻe he helehelena wale nō. ʻAʻole ia.
Hele nā kāleka i nā ʻeke. Loaʻa i nā ʻeke kāleka nā kāleka kāleka, nā kāleka ID a puni lākou, aia kekahi mau kaula hao. ʻO ka ʻeke nalu o ka mea hoʻohana i ka mea heluhelu, ʻaʻohe mea e hana, kāhea e hoʻopiʻi ua haki ke kāleka. ʻAʻole i haki ke kāleka-ua pale ʻia.
Ke kau nei nā keyfobs ma nā apo kī. Paʻa pololei ka mea hoʻohana i ka mea heluhelu. Heluhelu i kēlā me kēia manawa.
Ua hana pū mākou me kahi hui hoʻopuka hōʻailona hōʻailona ma Palani no ʻelima mau makahiki. Ma kahi o 500k FUID keyfobs i kēlā me kēia makahiki. Ua makemake mua lākou i nā kāleka. Hoʻololi ʻia ma hope o ka nui o nā kelepona kākoʻo "kāleka ʻaʻole hana". Ua emi koke ka nui o ka hoʻopiʻi. Ua hoʻololi pū lākou iā mākou me kā lākou hōʻailona kūʻokoʻa e pale ai i ka hoʻopunipuni ma kā lākou mākeke. ʻAʻole hiki i kēia ʻano hana maʻamau-ʻoihana kālepa ke hana. ʻAʻohe o lākou poʻi, nā mea kūʻai wale nō. Pono ʻoe i kahi mea hana RFID keyfob maoli no ka hoʻololi ʻana i nā mea hana.
He mea nui ka waiwai. He mea maʻalahi ka PVC akā nahā ma lalo o ka wili a me nā kemika. Loaʻa iā mākou kekahi mea kūʻai mai Pokukala e hana ana i ka hoʻokele hanana hanana-ma luna o hoʻokahi miliona mau lima lima i kēlā me kēia makahiki me 100k+ kāleka. Hana lākou i nā hanana pō, pono ka paʻi ʻana o UV fluorescent e ʻā ana ma lalo o ke kukui ʻeleʻele. ʻAʻole hiki i ka paʻi PVC maʻamau ke mālama iā ia, pono ke kaʻina hana kūikawā. Pono kēia ʻano koi i kahi hale hana e hoʻomohala i kāna mau hana ponoʻī.
Palekana chip-ʻaʻohe manaʻo o ka hapanui
EM4100 heluhelu-pili wale? E kūʻai i kope kope ma Taobao no iwakālua kālā, clone i kekona. Maikaʻi no ka nānā ʻana i nā mea hana, hoʻokele holoi lole. No ka puka puka? Hoʻohenehene. Ua ʻōlelo mākou i nā mea kūʻai aku "hoʻohana kā mākou hale hale i kēia." ʻO kaʻu mea e ʻōlelo ai, ʻo kou palekana hale ʻo ia ka hale keaka.
Hiki ke kākau hou ʻia ʻo T5577, kūpono no ka hoʻāʻo dev, akā ʻoi aku ka maikaʻi o ka palekana ma mua o EM4100 no ka mea ʻoi aku ka haʻahaʻa.
No ka hoʻomalu ʻana, ʻo ka uku -ka liʻiliʻi ʻo Mifare DESFire pae. AES encryption, hōʻoiaʻiʻo like. ʻOi aku ke kumukūʻai no kēlā me kēia chip, akā ʻoiaʻiʻo ka palekana.
E pili ana i ka ʻimi ʻana i nā mea hoʻolako
He mea hoʻohana ponoʻī kēia ʻāpana-, akā e ʻōlelo nō wau.
He nui nā ʻoihana kālepa RFID. Loaʻa lākou mai Factory A i kēia lā, Factory B ʻapōpō, ʻo wai ka mea ʻoi loa. ʻO kāu pūʻulu mua a me ka pūʻulu ʻelua mai nā hale hana ʻokoʻa loa. ʻO ka paʻa mau ʻana, ʻaʻohe hōʻoiaʻiʻo.
Hana mākou i kā mākou hoʻopaʻa chip ponoʻī, wili antenna, hoʻoheheʻe injection. ʻElima laina hana, i loko o kā mākou hale hana Hunan. Ua holo ʻo Auburn University RFID Lab i ka palapala hōʻoia ARC mai ka makahiki 2009. Pono ʻo Walmart, Costco i nā hōʻailona hōʻoia ARC-no ka mea, ʻokoʻa loa ka maikaʻi o ka ʻoihana, pono e hōʻoia kekahi.
Loaʻa kahi hui pāhana Tajikistan ma kahi o 2 miliona mau kāleka maʻamau mai iā mākou i kēlā me kēia makahiki no ka ʻauhau-panake, nā dute, nā pono hana, 250+ lawelawe. He kuleana ko nā papahana ma kēia pae ke hāʻule nā kāleka. ʻAʻole lākou e kiʻi mai i kahi hui kālepa.
Hiki i kahi hale hana RFID keyfob ke hoʻomalu i kāna hana ponoʻī ke hōʻoia i ka kūlike. ʻAʻole hiki i nā mea kālepa.
ʻO ka hope, e pili ana i ke kumukūʻai
Mai nana wale i ke kumu kuai.
ʻO ke kumu kūʻai hōʻailona haʻahaʻa akā ʻoi aku ka nui o ka hiki ʻole ke hoʻouna ʻoe i nā poʻe i nā pūnaewele e pani iā lākou-ʻo ia ke kumu kūʻai maoli. E kūʻai aku i nā mea heluhelu haʻahaʻa, ʻaʻole kākoʻo nā firmware hou iā lākou ma hope, e hoʻololi hou, ʻoi aku ka pipiʻi. Ke hoʻopiʻi ʻana o Middleware i kēlā me kēia kālepa, makaʻu nā bila i ka wā e piʻi ai ka nui.
I ka wā i hoʻopuka ai ʻo Inditex i ka RFID ma nā hale kūʻai Zara āpau ma 2016, ua hōʻike ʻo Wall Street Journal ua kūʻai lākou i 500 miliona mau pahu. Ua kapa ʻia ʻo Pablo Isla "kekahi o nā hoʻololi koʻikoʻi i ka hana ʻana o nā hale kūʻai." No ke aha lākou i hoʻolilo ai i kēlā kālā? No ka mea, ua helu lākou i ka huina kālā. ʻO ka loaʻa ʻana o ke koho pono ʻana e mālama i ka ʻoi aku ma mua o ke kumu kūʻai.
Pili ka loina like i nā papahana liʻiliʻi. E kiʻi pololei, holo mālie. E kuhi hewa, ʻeha mau loa.
ʻO ia kā mākou manaʻo. Loaʻa i kahi papahana kūikawā e kūkākūkā ai?
E hoʻouna i ka noi
