QR Code

One Dimension QR Code

Introduction of Bar Code Nowadays, technologies of bar code become widely used. It is the advantage thing to give us the information of goods such as names, prize or number of stock, etc. The majority of the popular bar code is one-dimension [1D] bar code. Even though one-dimension bar code are widely used, it still has limitation of the storage. So capability for store the information is developed such as increasing number of bar code digits or laying out multiple bar code. Thence two-dimension [2D] bar code is in vented.

Type of Two-Dimension[2D] Bar Code 1.

Maxi Code → was developed by Oniplanar Company in U.S.A. The maximum storage is 138 Numeric 93 Alphanumeric. Data Matrix → was developed by RVSI Acuity Cimatric U.S.A. in1989 QR Code → was developed by Denso Wave Company of Japan in 1994. QR Code is stand for “Quick Respond Code”, it mean high speed scan.

Let’s get the knowledge about QR Code!!!!

The Structure of QR Code •

•

Encoded Regions: is the part to store the code in the matrix style which can join for carry the data infinity. And it has the Error Correction. Function Pattern – Finder Pattern: contains the

rectangular at three corners, upper-right, upper-left and lowerleft which help to check position of QR Code for analysis. Timings Pattern: the material for join Finder Pattern at three corners to help for estimate and analyze the symbol. Format Information: are around the finder pattern and has the data for error correction.

Feature of QR code 1. Rectangular shape contains module of data from 21x 21 to 177x177 modules.

*** Module refer to black and white dot which are the data of QR Code

2. Small printout size QR code contains the data for horizontally and vertically

3. High capacity Encoding data QR code can carry all type of data, such as numeric and alphabetic characters, Kana, Kanji, Hiragana, symbols, binary and control codes QR code data capacity Numeric only Alphanumeric Binary ( 8 bit ) Kanji, full-width Kana

Max 7,089 Characters Max 4,296 Characters Max 2,953 Characters Max 1,817 Characters

4. Kanji and Kana Capability QR code can encode 13 bits, more than other 2D barcode 20%

5. Readable from any direction in 360 degree QR code can read at any direction for 360 degree. QR codes has the finder pattern which is used to indicate this code 6. Reading of QR code We can read with the both of reading machine and mobile phone for mobile phone. We use 3G system and install reading code program such as Quickmark and I-nigma 7. Structured append feature The large QR code can be divided into multiple data areas

8. Error correction capability QR code has error correction capability to restore if the QR code is dirty or damaged. For prevent information lost

QR code error correction capability Level L Approximate 7% Level M Approximate 15% Level Q Approximate 25% Level H Approximate 30% Raising this level improves error correction capability but increase the amount of data QR code size.

QR code standardization October, 1997

Approved as AIM International (Automatic Identification Manufactures International) standard (ISS – QR Code)

March, 1988

Approved as JEIDA (Japanese Electronic Industry Development Association) Standard (JEIDA - 55) Approved as JIS (Japanese Industrial Standards) standard (JIS X 0510) Approved as ISO international standard (ISO / IEC18004)

January, 1999 June, 2000

November, 2004 Micro QR Code is approved as JIS (Japanese Industrial Standards) Standard (JIS X 0510)

Translation of QR code • QR code much have censor to take the 2 dimensions information. That censor is CCD or CMOS camera. In addition, camera can analyze information such as alignment, contrast / brightness or threshold

Usage QR code can be classify into 2 types 1. Directly using Like price of product or personal information 2. Indirectly using That mean use QR code give name of website or phone number then, use mobile phone to link into information by consumer use mobile phone to take a QR code photograph, then reading program in mobile phone will analyze the information. Next mobile phone will ask you to link web address or phone number or not? If we accept answer, mobile phone will link to web address or phone number and then give information about that product and producer to your mobile phone. Quick mark is the new software. It has developed for use in open architecture of simple for example…. ACT Inc. pattern
