2D Bar-code FAQ

What are 2D bar-codes?

2D means "two dimensional". 2D bar-codes contain more information than conventional one dimensional linear bar-codes Conventional bar-codes get wider as more data is encoded. 2D bar-codes make use of the vertical dimension to pack in more data. 2D bar-codes have become possible as auto scanning CCD and laser scanners have replaced the original 'light pen' type of scanner. 2D bar-codes are also being used for tracking printed circuit boards in computer equipment.

What do 2D bar-codes look like?

Conventional 1D Bar-code
This is a conventional linear bar-code. It has a single row of bars- similar to a picket fence. The bar-code is called 'one dimensional' because all the data is encoded in the horizontal width. Increasing the data content can only be achieved by increasing the width. Beyond a certain point the bar-codebecomes too wide to scan easily.

2D Bar-code
This two dimensional bar-code. Data is encoded in both the horizontal and vertical dimensions. As more data is encoded the size of the bar-code can be increased in both the horizontal and vertical directions thus maintaining a manageable shape for easy scanning.

Will 2D bar-codes replace conventional 1D bar-codes?

No. Both technologies will coexist. 2D bar-codes will be used where 1D bar-codes cannot hold the necessary amount of data but 1D bar-codes have the advantage in low capacity applications like serial numbers.

When are 1D bar-codes better than 2D?

Although 1D bar-codes hold a smaller amount of data it is 'spread' over the whole height of the bar-code. The bar-code contains a high degree of redundancy. This means the bar-code can be read even with considerable degradation. If your application needs only a few characters (up to about 15) then a 1D bar-code is probably the best solution. Increasing the height of a 1D bar-code does not increase its capacity but it does increase its redundancy thus making it more resistant to degradation and obliteration and making it easier to scan.
