Automatic identification is essential for continuous and gapless product traceability. Code readers read printed codes, decode the data within the code and send the data to a computer.
The cost-effectiveness of the code readers is inevitable as they require little revenue for installation. Due to simple programming, they are accessible to implement, making the staff’s training easy. Additionally, encoding technology reduces the valuable time taken for the manual entering of data.
One-dimensional (1D or linear or “barcode”) and two-dimensional (2D) codes are used effectively in a variety of automatic identification applications, and in some cases are scanned using different types of technology. The difference between 1D and 2D barcode scanning relies on the layout and amount of data that can be stored in each:
