Makadi Contactless: ndi magwiridwe ndi chomasuka ntchito

Taonani zinthu zofunika ndi ubwino kuti contactless makadi. Popeza kuti iwo ndi yofunika zikuluzikulu za khadi anzeru, tidzakhala kuyamba kukambirana nawo.

makadi anzeru

Chotero anaitana makadi pulasitiki ndi Chip ophatikizidwa. Nambala ofala iwo muli opaleshoni dongosolo ndi microprocessor, zomwe kuteteza kupeza khadi, mwa kulankhula kwina, kuchititsa ntchito cryptographic: ntchito yosungirako ntchito makiyi, wosuta kutsimikizika, ntchito mu malo wodalirika.

Anzeru khadi - ndi madebiti ndi kadi, kuyenda, kudutsa mabungwe osiyanasiyana, makadi wophunzira, SIM-makadi, etc ...

Mitundu ya Anzeru Makadi

Gulu loyamba zachokera anzeru khadi wowerenga pa njira kuwombola:

• Contact (ISO 7816): makadi wotchuka ndi tchipisi kuti mulibe mabatire - amatenga owerenga mphamvu. Zikuphatikizapo makadi malipiro, "Sims", matikiti kwa payphones.
• Lumikizanani ndi USB: zoposa "zotsogola" Baibulo la mtundu woyamba umene Chip ndi Integrated ndi USB-wowerenga mu phukusi yaing'ono.
• Contactless anzeru makadi: mitundu imene kuwerenga nkhani zofunika kubweretsa khadi pafupi kwa owerenga. "Kulankhulana" ndi owerenga chikuchitika ndi nawo luso RFID. Izi makadi komanso alibe batire, mphamvu amasungidwa iwo ndi ntchito ya inductor, kuti ndi "Zingayambe" ntchito chipangizo. Zitsanzo: pakompyuta kuyenda, baji, zitupa biometric.

Gulu lachiwiri zachokera magwiridwe:

• makadi Memory: sitolo mwa iwo okha chilichonse kuchuluka kwa mfundo ndi njira kwa muzingochita chida chimenechi - mapasiwedi, zipinda wapadera, etc. Gulu ambiri - kuyenda, e-matikiti, makadi kwa mafoni malipiro ..
• Zanzeru: yodziwika ndi kukhalapo kwa microprocessor ndi luso kutsegula ma aligorivimu ntchito kwa iye, akuchita pansi pa ulamuliro wa opaleshoni dongosolo, muli m'ndandanda wa zikalata. Ndi SIM-makadi, e-zitupa ndi zikalata.

makadi Contactless ndi zizindikiro zawo

Kuti tinene pamwamba, tikhoza kuwonjezera kuti dzina onse a contactless zimagwirira ntchito mu kachitidwe malipiro ndi mfundo mwayi kulamulira.

ubwino waukulu ali motere:

• pafupifupi ziro kuthekera chinyengo;
• ndi yaitali yosungirako - zaka 10;
• mlingo deta wowerenga - nusu ya wachiwiri;
• Mwachangu - kuti overwrite zambiri angakhale mu osiyanasiyana nthawi 100 zikwi.
• kuthekera ntchito nthawi yaitali - khadi zochepa nkhani kuvala chifukwa cha kusowa kukhudzana ndi owerenga.

Standard wowerenga "anaona" contactless khadi pa mtunda wa masentimita 15, amene amalola inu kupeza chipangizo kwa malipiro kapena kulamulira thumba, thumba kapena kachikwama. Izi kwambiri Iyamba ntchito muyezo pa m'kaundula ndalama ndi turnstile (pafupifupi mpaka 40%).

Banks contactless makadi - kwambiri m'chilengedwe chonse, chifukwa ndipo Komanso anapereka ndi Chip ndi lamizeremizere maginito. Komabe, mtengo alandiridwa ndithu, ndi kuti akufotokoza pakutchulidwa ambiri makadi contactless mu moyo wathu wa tsiku ndi tsiku.

Zosiyanasiyana makadi contactless

makadi Contactless komanso ndi gulu lawo:

• EM-m'madzi: kwambiri ambiri contactless kupeza makadi (Tags). Mkati m'munsi pulasitiki anaika mlongoti ndi moyandikana Chip. chosiyana Mbali awo - .. Luso kuwerenga pa mtunda wa masentimita 70 ntchito ngati chilolezo cha magalimoto, magalimoto, malo olimba, masukulu, mayunivesite, zipatala, etc. Ndi thandizo lawo, kuganizira nthawi imene anthu ogwira ntchito mu mpanda wa bungwe, madalaivala kusamutsidwa zodutsa, malonda oimira ndipo T. d.
• MIFARE®: zake "pachimake" wapangidwa ndi mlongoti chinthu, microchip ndi kukumbukira okwezeka ndiponso achitetezo, chopatsilira ndi wolandila. The posonkhanitsa deta khadi angathe kusunga kwa zaka 10. Chinthu china ndi munthu wapadera chiwerengero n'zogwirizana mu umodzi wa Boma kukumbukira - zikhoza kugwiritsidwa ntchito ngati malamulo dzina.

• Anabisa moyandikana: choyambirira chikudutsa contactless makadi kuti ntchito pa zosiyanasiyana za lonse la kutentha. kuwerenga nawo - palibe masekondi oposa 0.1. Ndi Tri-mtundu LED ndi buzzer mumve lomveka ndi zithunzi za chifukwa chokhala ndi owerenga.

• Anabisa ICLASS: ndi ma aligorivimu zovuta zambiri, funsani owerenga ndi kubisa deta - deta HIV kumayambira kokha pamene khadi owerenga ndi kugawana makiyi wapadera. kusiyana kwawo ndi kuti iwo akhoza kusungidwa mu kukumbukira kwake , deta biometric monga zala. Ichi chizathandiza oyamba chipangizo mu maofesi chatsekedwa, T. Kwa. Reader akuyerekeza mfundo za zala pa mapu naye atatsamira pa chala mwini wabisika ICLASS.

Contactless khadi owerenga

Owerenga makadi contactless - zipangizo ntchito kuzindikira mfundo makadi contactless, unyolo kiyi mabaji, zibangili ndi zomata. Ambiri a iwo alandira chizindikiro, koma pali mitundu ya deta kulemba.

Owerenga anawagawa proximal - kuzindikira khadi pa mtunda wa 10 cm yaitali ndi -. Mamita 100 choyamba zimagwiritsa ntchito kachitidwe mwayi kulamulira, mfundo kulamulira. Lakutali, zomwe, poyamba, akhoza kulandira chizindikiro kwa makadi angapo ali mu ntchito makampani akuluakulu, mu mmene kukumana.
