Miyezo yolumikizirana yama tag pafupipafupi pawayilesi ndiyo maziko a kapangidwe ka chip tag.Miyezo yapano yapadziko lonse lapansi yolumikizirana ndi RFID makamaka ikuphatikizapo ISO/IEC 18000 muyezo, ISO11784/ISO11785 standard protocol, ISO/IEC 14443 standard, ISO/IEC 15693 standard, EPC standard, etc.

1. ISO/TEC 18000 idakhazikitsidwa ndi mulingo wapadziko lonse lapansi wozindikiritsa ma frequency a wailesi ndipo imatha kugawidwa m'magawo awa:

1).ISO 18000-1, magawo onse a mawonekedwe a mpweya, omwe amayimira tebulo lazolumikizirana ndi malamulo oyambira aufulu wamalumikizidwe omwe amawonedwa nthawi zambiri mu protocol yolumikizirana yama air interface.Mwanjira iyi, milingo yofananira ndi gulu lililonse la ma frequency safunikira mobwerezabwereza kunena zomwezo.

2).ISO 18000-2, magawo a mawonekedwe a mpweya omwe ali pansi pa 135KHz pafupipafupi, omwe amafotokozera mawonekedwe akuthupi a kulumikizana pakati pa ma tag ndi owerenga.Wowerenga azitha kulumikizana ndi ma tag a Type+A (FDX) ndi Type+B (HDX);imatchula ndondomeko ndi malangizo kuphatikiza njira zotsutsana ndi kugunda zolumikizirana ma tag ambiri.

3).ISO 18000-3, magawo a mawonekedwe a mpweya pa 13.56MHz pafupipafupi, omwe amafotokozera mawonekedwe, ma protocol ndi malamulo pakati pa owerenga ndi tag kuphatikiza njira zotsutsana ndi kugunda.Protocol yotsutsana ndi kugunda imatha kugawidwa m'njira ziwiri, ndipo mawonekedwe 1 amagawidwa kukhala mtundu woyambira ndi ma protocol awiri owonjezera.Mode 2 imagwiritsa ntchito protocol ya FTDMA yochulukitsa nthawi, yokhala ndi ma tchanelo a 8, omwe ndi oyenera nthawi yomwe ma tag ndi akulu.

4).ISO 18000-4, magawo a mawonekedwe a mpweya pa 2.45GHz pafupipafupi, 2.45GHz air interface parameters, yomwe imatchula mawonekedwe akuthupi, ma protocol ndi malamulo pakati pa owerenga ndi tag kuphatikiza njira zotsutsana ndi kugunda.Muyezo umaphatikizapo mitundu iwiri.Mode 1 ndi tag yomwe imagwira ntchito mwa owerenga-wolemba-poyamba;Mode 2 ndi tag yogwira yomwe imagwira ntchito ngati tag-poyamba.

5).ISO 18000-6, magawo a mawonekedwe a mpweya pa 860-960MHz pafupipafupi: Imatchula mawonekedwe, ma protocol ndi malamulo pakati pa owerenga ndi tag kuphatikiza njira zotsutsana ndi kugunda.Lili ndi mitundu itatu ya ma protocol ophatikizira ophatikizika: TypeA, TypeB ndi TypeC.Mtunda wolumikizana ukhoza kufika kupitirira 10m.Pakati pawo, TypeC inalembedwa ndi EPCglobal ndipo inavomerezedwa mu July 2006. Ili ndi ubwino pa kuzindikira liwiro, liwiro kuwerenga, kulemba liwiro, mphamvu deta, odana ndi kugunda, chitetezo zambiri, pafupipafupi gulu kusinthasintha, odana kusokoneza, etc., ndipo izo. ndi omwe amagwiritsidwa ntchito kwambiri.Kuphatikiza apo, ma radio frequency band omwe alipo pano amakhazikika mu 902-928mhz, ndi 865-868mhz.

6).ISO 18000-7, magawo a mawonekedwe a mpweya pa 433MHz pafupipafupi, 433+MHz magawo olumikizirana olumikizana ndi mpweya, omwe amafotokozera mawonekedwe, ma protocol ndi malamulo pakati pa owerenga ndi tag kuphatikiza njira zotsutsana ndi kugunda.Ma tag omwe ali ndi mawerengedwe ambiri ndipo ndi oyenera kutsatira zinthu zazikulu zosasunthika.

2. ISO11784, ISO11785 protocol muyezo: The low-frequency band operating frequency range is 30kHz ~ 300kHz.Mafupipafupi ogwiritsira ntchito ndi: 125KHz, 133KHz, 134.2khz.Mtunda wolumikizirana wama tag otsika nthawi zambiri umakhala wosakwana mita imodzi.
ISO 11784 ndi ISO 11785 motsatana motsatana motsatana amafotokozera kalembedwe kachidindo ndi malangizo aukadaulo ozindikiritsa nyama.Muyezo sunatchule kalembedwe ndi kukula kwa transponder, kotero ukhoza kupangidwa m'njira zosiyanasiyana zoyenera nyama zomwe zikukhudzidwa, monga machubu agalasi, makutu kapena makola.dikirani.

3. ISO 14443: Muyezo wapadziko lonse wa ISO14443 umatanthawuza mawonekedwe awiri a zizindikiro: TypeA ndi TypeB.ISO14443A ndi B sizigwirizana.
ISO 14443A: Nthawi zambiri amagwiritsidwa ntchito poyang'anira makhadi, makhadi amabasi ndi makhadi ang'onoang'ono osungidwa amtengo wapatali, ndi zina zambiri, ndipo ali ndi gawo lalikulu pamsika.
ISO14443B: Chifukwa cha kuchuluka kwa encryption coefficient, ndiyoyenera makhadi a CPU ndipo imagwiritsidwa ntchito ngati ma ID, mapasipoti, makhadi a UnionPay, ndi zina zambiri.

4. ISO 15693: Iyi ndi njira yolumikizirana mtunda wautali.Poyerekeza ndi ISO 14443, mtunda wowerenga uli patali.Amagwiritsidwa ntchito makamaka nthawi zomwe zilembo zambiri zimafunikira kuzindikirika mwachangu, monga kasamalidwe ka zinthu, kutsata kasamalidwe kazinthu, ndi zina zambiri. ISO 15693 ili ndi liwiro la kulumikizana mwachangu, koma mphamvu yake yolimbana ndi kugunda ndi yofooka kuposa ISO 14443.
