2D code is not only QR Code, to see what you have seen ?

2D pa code( 2-dimensional bar code ) faʻamaumau faʻamatalaga faʻailoga faʻamatalaga e faʻaaoga ai ata uliuli ma paʻepaʻe faʻasalalau i totonu o se vaalele (tulaga lua-dimensional) e tusa ai ma tulafono patino i se geometry ua tuʻuina atu. I le tuufaatasiga o tulafono, o manatu o le '0' ma le '1' bit streams, lea e aofia ai le faʻavae totonu o le komepiuta, e faʻaaogaina ma le poto. O le tele o foliga geometric e fetaui ma le binary o loʻo faʻaaogaina e fai ma sui o faʻamatalaga numera o le tusitusiga, ma o faʻamatalaga e otometi lava ona faʻagasolo le faitau otometi o le masini faʻaoga ata poʻo le masini suʻesuʻe ata. O lo'o i ai ni uiga masani o le pa'u fa'atekonolosi: e tofu lava le code ma lana seti uiga fa'apitoa. E tofu uiga ta'itasi ma lona lautele. E iai se galuega fa'amaonia. I le taimi lava e tasi, o loʻo i ai foʻi le galuega o le faʻaalia otometi o laina eseese o faʻamatalaga ma le faʻaogaina o ata suiga suiga suiga.

O le 2D code o se fa'asologa o fa'ailoga pa e sili atu le maualuga nai lo le 1d code. 1d code e mafai ona faʻaalia faʻamatalaga i le tasi itu (e masani lava faʻataʻitaʻiga), aʻo 2d code e mafai ona teuina faʻamatalaga i itu uma e lua ma faʻasaga i luga. 1d code e mafai ona na'o numera ma mataitusi, a'o 2d code e mafai ona teuina fa'amatalaga e pei o mataitusi Saina, numera ma ata, o lea e sili atu le lautele o le fa'aoga o le 2d code.

E tusa ai ma le mataupu faavae o le 2d code, lua-dimensional code e mafai ona vaevaeina i ni vaega se lua: matrix 2d code ma stacked / row 2d code.

Matrix 2d code Matrix 2d code, lea e ta'ua o le chessboard 2d code, o lo'o fa'ailogaina i se avanoa fa'afa'afa'afa e ala i tufatufa eseese o pika uliuli ma pa'epa'e i le matrix. I le tulaga tutusa elemene o le matrix, o le binary '1' o loʻo faʻatusalia e foliga o togi (faʻailoga sikuea, faʻailoga lapotopoto poʻo isi foliga), ma le binary '0' e le o faʻatusalia e foliga o togi. O le fa'aogaina ma le tu'ufa'atasiga o togi e iloa ai le uiga o lo'o fa'atusalia e le matrix 2d barcode. Matrix 2d bar code o se ituaiga fou o faʻailoga otometi faʻailoga faʻailoga ma le faʻaogaina o tulafono faʻavae e faʻavae i luga o tekonolosi faʻaogaina ata ma tuʻufaʻatasia le faʻasologa o tulafono. O le faʻailoga faʻailoga 2d faʻailoga o QR Code, Data Matrix, MaxiCode, Han Xin Code, Grid Matrix, ma isi.

QR Code

QR Code ole Quick Response Code fast response matrix code, fa'aigoa ole Denso QR Code. O se matrix 2d bar code fa'asalaina e fa'alapotopotoga fa'ava-o-malo, lea na muamua fausia e Denso, Iapani, ia Setema 1994. O le tulaga fa'a-Saina na ta'ua o le fa'ailoga vave tali matrix. I le faaopoopo atu i uiga o le 1d bar code, o loʻo i ai foi le lelei o le tele o faʻamatalaga faʻamatalaga, maualuga le faʻatuatuaina, laʻititi avanoa avanoa, faʻaogaina lelei o faʻamatalaga faʻamatalaga eseese, lagolagoina le 360 ° faʻatonuga faʻatonu tulafono faitau, faʻatonuga faʻasaʻo mea sese, ma malosi faʻalilolilo. ma le tetee i le faafoliga. Lagolago mataitusi ASCII ma mataitusi lautele ASCII.

O le Micro QR o se auala fou 2d coding ua faʻatulagaina ile ISO: 2006 pepa, tutusa ma le QR. Ae ui i lea, pe a faʻatusatusa i le QR 2d code, Micro QR o loʻo i ai uiga nei: naʻo le tasi le faʻailoga suʻesuʻe e manaʻomia, ma e laʻititi le voluma.

Fa'amatalaga Fa'amatalaga

Faʻamatalaga Faʻamatalaga, na muamua taʻua Faʻamaumauga Faʻamaumauga, na fatuina e International Data Matrix ( ID Matrix ) i le 1989. E mafai ona vaevaeina Faʻamatalaga Faʻamatalaga i ECC000-140 ma ECC200, ECC200 e masani ona faʻaaogaina. Fa'amatalaga Matrix e lagolagoina mataitusi ASCII ma mataitusi lautele ASCII. e masani ona fa'aaogaina mo fa'amatalaga numera fa'asologa o oloa laiti.

Grid Matrix

Grid Matrix, e taʻua o le GM code, o se sikuea 2d code. O le fa'ailoga fa'ailoga o lo'o faia i sikuea sikuea sikuea, ma o fa'ata'ita'iga ta'itasi e aofia ai le 6x6 sikuea sikuea.

Fa'aputu / laina 2d code

O le fa'aputuga / laina-parallel 2d bar code e ta'ua fo'i fa'aputu 2d bar code po'o le layer-parallel 2d bar code. O lona fa'atonuga fa'avae e fa'avae i luga o le 1d bar code, lea e fa'aputu i ni laina se lua pe sili atu pe a mana'omia. E maua ai nisi o uiga o le 1d bar code i le coding design, faʻamaoniga mataupu faavae ma le faitau faitau. O mea faigaluega faitau e fetaui ma le lomitusi pa code ma le 1d bar code technology. Ae ui i lea, ona o le faateleina o le numera o laina, e tatau ona fuafua laina, ma o le decoding algorithm e le tutusa ma le polokalama. Laina sui ituaiga 2d pa code : PDF417 (e masani ona faʻaaogaina), Micro PDF417, Code 16K, CODABLOCK F, Code 49, ma isi.

PDF 417

O le PDF417 o loʻo faʻaaogaina nei le 2d code e sili ona faʻaaogaina. O le pa code o se ituaiga o code bar code maualuga, i le eria lava e tasi nai lo code 2d masani e mafai ona faʻaogaina atili faʻamatalaga. Fa'aaoga lautele i tiketi lotoa, tiketi ea, vaaiga faitau ID.

Su'e tau taugofie mae sili atu le lelei o le barcode scannermo lau pisinisi?
