Yuav ua li cas los txiav suab ntawm cov QR-code rau lub computer?

Ib tug ntawm cov ib qhov chaw ntawm lub neej txhua hnub, nyob rau hauv kev lub digital ntiaj teb no, tau los ua ib tug QR-code uas yog muaj peev xwm nyeem txhua txhua. Qhov no zoo ntawm encryption yuav pom kiag li qhov txhia chaw: nyob rau hauv lub ntim ntawm cov khoom nyob rau hauv lub thawv thiab lwm yam khoom vaj khoom tsev, booklets, phau ntawv qhia, ntawv xov xwm. Nyob rau hauv Feem ntau, tsis muaj leej twg ntawm cov ntaub ntawv tau sau ntawv nyob rau hauv ib daim ntawv los yog lwm, tsis yog tsis muaj ib tug QR-code. Hais txog nws nyob rau hauv no tsab xov xwm yuav tsum tau los sib tham. Tus nyeem ntawv yuav kawm ntxiv txog qhov no txoj kev, cov ntaub ntawv yog encrypted thiab yuav ua li cas los txiav suab ntawm cov QR-code nrog koj lub xov tooj thiab lub computer.

Keeb kwm ntawm creation

Yog li ntawd, dab tsi yog meant los ntawm ib tug uas zoo sib xws zoo ntawm cipher? Nws yog heev yooj yim: QR - ib tug tsiaj ntawv ntawm cov lus ceev lus teb, uas txhais ua lus Askiv txhais tau tias "ceev teb" los yog "ceev cov lus teb." Ib tug QR code - qhov thiaj li hu ua ob-dimensional bar code, uas yog tsim thiab nkag tau rau hauv 1994 ib tug Japanese lub tuam txhab hu ua Denso Wave. QR-code tau decipher hais tias tom qab nyeem ntawv no tsab xov xwm tsis siv sij hawm ntau los ua kom tsim nyog raws qhov tseeb hais tias Japanese tuam txhab uas muag tsis muaj tus nqi ntawm cov ntaub ntawv uas yuav tsum tau muab tso rau hauv lub niaj zaus ib tug-dimensional barcode.

Tus nrog paub txog cov txheej txheem

Yog hais tias koj saib nyob rau cov hom ntawm cov code ceev teb, koj yuav saib tau lub square nrog xav txog tej yam tsis muaj neeg pom sab, hauv uas lwm cov lub rho los ntawm txawv lengths thiab ntau thiab tsawg. Nws yog nyob rau hauv lawv, thiab pw tag nrho cov ntawv nyeem ntaub ntawv nyob rau hauv ib tug encrypted two-dimensional code.

Tag nrho cov uas yog yuav tsum tau mus txiav suab ntawm cov QR-code rau lub computer - ib tug tshwj xeeb scanner uas nyeem ib tug duab zoo li ib tug bar code scanner. Qhov txawv tsuas yog hais tias lub infrared scanner nyeem ntawv bar ci tsuas yog ib sawb thaum lub QR-code yog pom raws li ib ob-dimensional duab los ntawm radiating ib tug loj tus naj npawb ntawm xws ib daim hlab.

Qhov zoo ntawm kev siv

Tus thawj hnov txawv cipher ceev lus teb los ntawm cov ib txwm bar code - yog tus nqi ntawm cov ntaub ntawv uas yuav tsum tau muab tso rau hauv nws. Thaum lub "bar" tsuas txhawb alphanumeric cim, QR tso cai rau koj mus pw ib tsab ntawv, lo lus thiab tag nrho ua ke.

Yog hais tias peb coj cov loj tshaj plaws QR-code rau decipher lub "hauv" los yog nyob rau hauv lub computer, nws yuav pom tias lub siab tshaj plaws pes tsawg tus ntawm tug lej tom qab muaj nyob rau hauv lub code - 7089. Nyob rau hauv tas li ntawd, koj muaj peev xwm tso tau txog 4296 xov tooj thiab cov tsiaj ntawv nyob rau hauv lub Latin tsiaj ntawv nyob rau hauv nws. Yog hais tias peb tham txog binary code, ces tus xov tooj uas tau ntaub ntawv tso cia me ntsis me me - 2953 bytes.

chaw

Thaum nyob rau hauv 1994 lub tuam txhab Denso Wave tau tsim thiab muaj ntawv tso cai nws cov khoom, nws cov tswv thiab tsis suav rau cov ua muaj koob meej ntawm lub invention. Tsim QR-code yog cia li mus them ntau lawm xav tau kev pab ntawm ib tug neeg tuam txhab uas muag. Tom qab tag nrho, QR-code, decipher thiab paub txog tias yooj yim heev, yuav txo tau ntau ntau lawm dab mus rau ib tug ob peb lub vib nas this.

Tom qab ntawd, nyob rau hauv nruab nrab-2000s, thaum thawj smartphone nrog lub koob yees duab, thiab tom qab lawv - Kua iPhone thiab lwm yam newer pab kiag li lawm, QR-code pib mus nce chaw dua. Qhov no yog hais tias daim ntaub ntawv uas tau nyeem cov code nrog cov ntaus lub koob yees duab yuav tau ua nws nyob rau hauv ib tug teeb meem ntawm vib nas this. Ntxiv mus, cov ntaub ntawv muaj nyob rau hauv lub QR, tau tag nrho qhia mus, emails, SMS, hu, thiab txawm dluab png tawm tswv yim, JPG thiab GIF dluab ntawm mus txog rau 4 KB. Cov yav tas, los ntawm txoj kev, tsis noj paus nyob rau hauv lub niaj hnub ntiaj teb no thiab yog siv heev tsis tshua muaj.

Yuav ua li cas los txiav suab ntawm cov QR-code

Android- thiab iOS no smartphones tau ntev lawm ib tug lossis loj tus naj npawb ntawm daim ntaub ntawv rau paub txog ob-dimensional cipher. Qhov tseem ceeb tshaj uas yuav tsum tau - lub xub ntiag ntawm lub koob yees duab nrog zoo kev daws teeb meem thiab, dua li, autofocus. Lub fact tias cov decryption code yuav tsum tau ib tug ntshiab duab, li ntawd, hais tias ib tug pheej yig smartphone uas muaj 2 megapixel lub koob yees duab tsis muaj autofocus, feem ntau yuav, tsis tau nyeem cov lus qhia. Tab sis xav tias zoo tagnrho tej yam kev mob, thaum lub ntse xov tooj yog zoo txaus, thiab cov chamber, ntsig txog, uas muaj kev daws teeb meem thiab ua kom pom tseeb.

Yog hais tias koj tsuas tig mus rau ntawm lub koob yees duab app thiab coj nyob rau hauv lub QR-code, ntawm chav kawm, nws yuav tsis ua hauj lwm, thiab cov code yog tsis yog tsis paub. Qhov ntawd yog vim hais tias koj yuav tsum nyeem ib tug tshwj xeeb daim ntawv thov-decoder. Qhov twg tau txais nws? Nyob rau hauv cov ntaub ntawv no ib yam nkaus thiab, tag nrho cov heev yooj yim: zoo xws li cov ntaub ntawv sau npe yog tag nrho ntawm cov khw ntawm mobile daim ntaub ntawv, xws li nyob rau hauv lub iPhone AppStore thiab ua si ua lag luam nyob rau hauv. Cov nrhiav bar yuav tsum nkag mus rau qhov kawg thov «QR-code scanner" los yog tsuas yog «QR scanner." Tom qab lub tsos ntawm cov kev tshwm sim, xaiv tej vending daim ntawv thov, nruab thiab khiav nws. Cov kev txaus siab ntawm cov QR-code kom lub koob yees duab rau ntawm ob sab thiab nyob kiag li tej lub. Daim ntawv thov nws tus kheej qhia txog cov kev kawm ntaub ntawv mus rau cov zaub. Piv txwv li, yog hais tias nws yog ib qhov txuas mus rau ib tug website, txiav pib lub neej ntawd browser yog twb qhib page.

Yog hais tias peb tham txog paub txog ib tug QR-code rau lub computer, muaj kuj yog tsis muaj dab tsi nyuab. Qhov loj tshaj plaws - lub xub ntiag ntawm lub yam scanner. Qhov yooj yim txoj kev - yog mus qhib ib tug ntawv nyeem editor thiab muab tso rau tej yam uas nyob rau hauv ob-dimensional code scanner. Raws li ib tug tshwm sim, cov zaub tag nrho cov ntaub ntawv tsim nyog yuav tau muab nyob rau hauv phau ntawv daim ntawv.

Uas siv QR-code

Cov feem nthuav txoj kev uas yuav siv tau cov no cov lis dej num - nws prints rau T-shirts, dab tsi ua rau ntau yam txawv teb chaws online khw muag khoom noj. Ntawm kab hauv qab no yog hais tias ib tug neeg uas xav kom tau raws li cov neeg tshiab, daim ntawv ntawm ib qhov txuas mus rau koj lub profile nyob rau hauv cov kev sib raug. tes hauj lwm ntawm tib QR-code, uas, nyob rau hauv lem, yog sau rau ntawm ib T-shirt. Raws li ib tug tshwm sim - txhua leej txhua tus uas pom qhov no zoo ntawm "square" rau cov khaub ncaws ntawm lwm tus neeg, muaj peev xwm "nyeem" nws thiab ces ntxiv rau lawv cov phooj ywg.

Tsis muaj tsawg pab QR nyob rau hauv lub advertising kev lag luam. Yog li ntawd, muaj ntau yam tuam txhab uas muag sau banners nrog rau tag nrho ob-dimensional ciphers rau txhua leej txhua tus dua los ntawm los yog txawm los ntawm afar yuav luam theej duab ntaub ntawv feem ntau muaj cov ib qhov txuas mus rau lub tuam txhab website. Nyob rau hauv tas li ntawd, kom koj thiaj li muaj peev xwm thab muag khoom tsis tsuas websites, tab sis kuj cais cov khoom. Piv txwv li, QR-code, decipher uas yog tam sim no tsis yooj yim, hos yog ib yam los yog lwm wardrobe ncaj qha los ntawm lub chaw tsim tshuaj paus. Ib tug txiv neej zaum nyob rau hauv ib tug Cafe nyob rau hauv ib tug zoo nkauj lub tsho, sau cov code luam. Cov neeg uas nyiam lub tsho, yuav yooj yim luam theej duab cov code thiab mus ncaj qha mus rau qhov muag nplooj ntawv no heev lub tsho. Thiab cov neeg zoo, thiab lub tuam txhab profits.

Summing li, peb yuav hais tias, ua tsaug rau QR-code, nqi ntawm cov ntaub ntawv nyob rau hauv lub niaj hnub ntiaj teb no tau ua ntau ntau tsi zoo thiab yooj yim dua. Ntawm cov hoob kawm, ntse cov xov tooj yuav luam theej duab thiab ib tug yooj yim one-dimensional bar lis dej num, tab sis lub caij nyoog kawg no tsis muaj txaus cov lus qhia, uas ua rau ob-seem lis dej num thiab nrov dua. Uas yog vim li cas koj yuav tsum tsis txhob yuav tub nkeeg mus download tau lub app-decoder rau koj smartphone. Tom qab tag nrho cov, leej twg paub qhov twg thiab thaum twg koj xav tau ib tug QR-code paub.
