Contactless phaib: lub functionality thiab yooj yim ntawm kev siv

Xav txog qhov tseem ceeb nta thiab zoo uas contactless phaib. Txij li thaum lawv yog ib feem ntawm cov ntse card, peb yuav pib sib tham nrog lawv.

Ntse phaib

Yog li ntawd hu ua yas cards nrog kos nti. Lub prevailing tooj ntawm lawv muaj cov operating system thiab microprocessor, uas tiv thaiv kev nkag mus rau hauv daim ntawv, nyob rau hauv lwm yam lus, kev cryptographic hauj lwm: cia haujlwm siv lub lag luam, cov neeg siv authentication, lub lag luam nyob rau hauv ib tug neeg ib puag ncig.

Ntse card - ib daim debit thiab credit cards, mus ncig teb chaws, hla ntau lub koom haum, tus menyuam kawm ntawv cov ntawv teev lus, sim-phaib, thiab lwm yam ...

Hom ntse phaib

Tus thawj kev faib yog raws li ntse card nyeem ntawv rau txoj kev mus rau kev sib pauv:

• Tiv tauj (ISO 7816): nto moo cards nrog chips uas tsis muaj roj teeb - yuav siv sij hawm zog txawj nyeem ntawv. Cov no muaj xws them nqi ntawv, "Sims", daim pib rau payphones.
• Hu nrog USB: qhov ntau "advanced" version ntawm cov thawj hom, nyob rau hauv uas lub nti yog kev nrog ib tug USB-nyeem ntawv nyob rau hauv ib tug me me pob.
• Contactless ntse phaib: ib tug tsiaj nyob rau hauv uas mus nyeem cov ntaub ntawv tsim nyog los coj daim card ze rau tus nyeem ntawv. "Kev sib txuas lus" nrog rau cov nyeem ntawv yuav siv sij hawm qhov chaw nrog kev koom tes ntawm RFID technology. Cov cards kuj tsis muaj ib lub roj teeb, lub zog yog muab nyob rau hauv lawv los ntawm kev siv lub inductor, uas thiab "txau" lag luam ntawm lub ntaus ntawv. Piv txwv: hluav taws xob mus ncig teb chaws, cov ntawv uas qhia, biometric passports.

Qhov thib ob kev faib yog raws li nyob rau hauv functionality:

• Nco phaib: cia nyob rau hauv lawv tus kheej tej nqi ntawm cov ntaub ntawv thiab mechanisms rau restricting nkag tau mus rau nws - passwords, cim chav, lwm yam feem ntau pab pawg neeg - mus ncig teb chaws, e-daim pib, phaib them nyiaj tes ..
• Intelligent: tsiag ntawv los ntawm xub ntiag ntawm lub microprocessor thiab muaj peev xwm mus thauj khoom algorithms ua hauj lwm rau nws, kuj nyob rau hauv cov cai ntawm cov operating system, muaj ib tug txheej ntawm daim ntawv pov. Nws yog sim-cards, e-passports thiab visas.

Contactless phaib thiab lawv nta

Yuav kom paraphrase saum toj no, peb muaj peev xwm ntxiv hais tias nws yog tus general lub npe ntawm contactless mechanisms siv nyob rau hauv kev them nyiaj systems, thiab kev nkag tau mus tswj cov ntsiab lus.

Lawv lub ntsiab zoo yog raws li nram no:

• yuav luag pes tsawg tau cuav;
• ib tug ntev lub sij hawm cia - txog li 10 xyoo;
• cov ntaub ntawv tus nqi nyeem ntawv - feem ntawm ib tug thib ob;
• efficiency - mus overwrite cov ntaub ntawv yuav ua tau nyob rau hauv ntau ntawm 100 txhiab lub sij hawm.
• tau ntev-lub sij hawm kev siv - card tsawg kawm hnav vim tsis muaj kev sib cuag nrog tus nyeem ntawv.

Standard nyeem ntawv "pom" contactless card rau ntawm ib tug deb ntawm 15 cm, uas tso cai rau koj mus tsis tau rau hauv lub ntaus ntawv rau kev them nqi los yog kev tswj ntawm lub hnab, lub hnab tshos los yog lub hnab tawv pojniam. Qhov no ho accelerates tus txheej txheem ua hauj lwm ntawm cov nyiaj ntsuab register thiab cov turnstile (kwv yees li thaum mus txog 40%).

Ntug dej contactless phaib - lub feem ntau universal, vim hais tias thiab lawv ntxiv muab ib nti thiab ib tug sib nqus stripe. Txawm li cas los, lawv cov nqi yog heev tau, thiab uas piav txog lub thoob plaws tshwm sim ntawm contactless cards nyob rau hauv peb lub neej txhua hnub.

Ntau hom contactless phaib

Contactless phaib kuj muaj lawv tus kheej kev faib:

• Em-marine: lub feem ntau ntau contactless nkag phaib (cim npe). Hauv lub yas puag muab tso rau kav hlau txais xov thiab sib thooj nti. Lawv txawv feature - .. Muaj peevxwm nyeem tau ntawm ib tug deb ntawm mus txog rau 70 cm yog siv raws li lub chaw nres tsheb daim ntawv tso cai, chaw nres tsheb, qoj chaw zov me nyuam, tsev kawm ntawv, universities, kev kho mob cov chaw, thiab lwm yam Nrog lawv pab, coj mus rau hauv tus account lub sij hawm siv ua hauj lwm nyob rau hauv lub phab ntsa ntawm lub koom haum, cov neeg tsav tsheb xaav tseem khiav, kev muag khoom cov neeg sawv cev thiab t. d.
• MIFARE®: nws "core" yog muaj li ntawm ib tug kav hlau txais xov, ib tug microchip nrog ib tug ruaj ntseg nco, lub transmitter thiab receiver. Cov ntaub ntawv nyob rau hauv daim card yuav khaws mus txog rau 10 xyoo. Lwm feature yog nws tug xov tooj uas fits rau hauv ib tug ntawm lub cim xeeb sectors - nws yuav siv tau raws li ib tug qhia tau code.

• Khiav nkaum sib thooj: thawj-pass contactless ntawv uas khiav lag luam ntawm lub ntau yam ntawm kub. nyeem ntawv lub sij hawm nrog lawv - tsis muaj ntau tshaj li 0.1 vib nas this. Muaj ib tug tri-xim LED thiab buzzer rau audible thiab pom tau qhov sib ntaub ntawv hais txog lub txiaj ntsim ntawm kev sib cuag nrog tus nyeem ntawv.

• Khiav nkaum ICLASS: muaj ntau algorithms, hu rau nyeem ntawv thiab cov ntaub ntawv encryption - cov ntaub ntawv kis tau tus mob pib tsuas yog thaum lub card nyeem ntawv thiab qhia tshwj xeeb tuav. Lawv txawv yog hais tias lawv yuav tsum tau muab cia rau hauv nws lub cim xeeb , biometric cov ntaub ntawv xws li tuabneeg. Qhov no pub rau cov kev taw qhia ntawm tus dais nyob rau hauv lub kaw cov vaj tse, t. Yuav kom. Nyeem ntawv piv cov ntaub ntawv hais txog cov tuabneeg nyob hauv daim ntawv qhia nrog nws leaning tiv thaiv Khiav nkaum ICLASS tswv ntiv tes.

Contactless card nyeem ntawv

Txawj nyeem ntawv ntawm contactless phaib - pab kiag li lawm siv kom paub txog cov lus qhia los ntawm contactless phaib, qhov tseem ceeb chains, badges, bracelets thiab stickers. Feem coob ntawm lawv tsuas tau txais lub teeb liab, tab sis muaj cov hom ntawm kev sau ntawv cov ntaub ntawv.

Txawj nyeem ntawv yog muab faib ua proximal - paub lub card rau ntawm ib tug deb ntawm 10 cm ntev thiab -. 100 m thawj mas siv rau kev nkag mus tswj lub nruab, tswj cov ntsiab lus. Nyob deb npaum, uas, incidentally, muaj peev xwm tau txais lub teeb liab los ntawm ntau yam cards yog nyob rau hauv kev siv nyob rau hauv loj Enterprises, nyob rau hauv logistics.
