- Barcodes are symbols that can be scanned electronically using laser or camera-based systems.
- They are used to encode information such as product numbers, serial numbers and batch numbers.
- Barcodes play a key role in supply chains, enabling parties like retailers, manufacturers, transport providers and hospitals to automatically identify and track products as they move through the supply chain.
One Dimensional BarCodes:
- Contain data that is read along the length of the barcode.
- May contain numbers only, alpha-numeric data , or a limited set of alphabetical characters.
- Typically, these are ASCII characters.
Two-Dimensional BarCodes:
- A 2D (two-dimensional) barcode is a graphical image that stores information both horizontally -- as one-dimensional bar codes do -- and vertically.
- 2D barcodes are also known as quick response codes because they enable fast data access.
