The principle and features of atitit Data Matrix DM Code

Datamatrix formerly known as Datacode, by the United States International Information Corporation (International data Matrix, referred to as ID Matrix) was invented in the 1989 years.

Datamatrix is a matrix-type Two-dimensional barcode , the idea is to deposit more data on smaller barcode labels. The minimum size of the Datamatrix is the smallest in all current barcodes, especially for small parts, and for direct printing on solids.

Datamatrixcan also be divided intoecc000-140with theECC200two different types,ecc000-140with many different levels of error correction, andECC200then throughReed-solomonalgorithm to generate a polynomial to calculate the error correction code, its size can be printed in different sizes according to demand, but the use of error correction code should be matched with the size, because its algorithm is easier, and the size is more flexible, it is generallyECC200is more common, this section only describesECC200Specifications ofDatamatrixcode, the following is saidDatamatrixin fact, they all meanECC200terms.

1.1. Features of Datamatrix

Edit

datamatrix DM Code research is also less. datamatrix code is a matrix of two-dimensional barcode, the biggest feature is the high density, Its minimum size is the smallest code in all current barcodes. DM code can be in just 25mm? 30 number. DM Using the complex error correcting code technology, the code has a strong anti-pollution ability. datamatrix DM code has become the Korean mobile phone two-dimensional barcode mainstream technology.

1.2. Use

Edit

the two-dimensional barcode has the characteristics of large storage, high secrecy, high tracking, strong damage resistance, large redundancy, and low cost, which are especially applicable to forms, security, tracking, license, stock count, data backup and so on.
form Application
document form, business form, import and export declarations, manifest and other information transfer exchange, reduce manual re-input form data, avoid human error, reduce labor costs
Confidential Applications
the encryption and transmission of confidential information such as business intelligence, economic intelligence, political intelligence, military intelligence and private information.
Tracking Apps
Automatic Document tracking, automatic tracking of production line parts, automatic tracking of customer service, automatic tracking of mail order delivery, automatic tracking of maintenance records, automatic tracking of dangerous items, automatic tracking of back-up supplies, automatic tracking of Medical Checkup, ecological research ( animals, birds ...) ) Auto-tracking, etc.
License Application
Passport, ID card, registration card, driver's license, membership cards, identification card, chain store membership card and other information registration and automatic input, play "with to read", "Instant access" information management effect.
Counting Apps
The automatic inventory of goods and fixed assets of Logistics center, Warehousing Center, Joint Service Center, and give full play to "immediate inventory, immediate decision-making" effect.
Redundancy Applications
document form Information if unwilling or unable to disk, CD-ROM and other electronic media storage backup, you can use two-dimensional barcode to save the backup, easy to carry, not afraid of folding, save a long time, and can photocopy fax, do more backups.
network resources download can be applied to the online download of resources, such as e-books, games, applications and so on

anti-counterfeiting role: More for the product packaging, due to the binary structure of the two-dimensional code, product traceability has a great help [2]  

1.3.Zxing is an open source Java The class library is used to parse 1d/2d barcodes in a variety of formats . The goal is to decode the QR code, Data Matrix, and UPC 1D barcodes. It provides clients under a variety of platforms including: J2ME, J2SE, and Android.
