The benefits of a bar coding system is far reaching. It tracks storage and retrieval, picking and packing, increases productivity, and reduces inventory costs. It also helps to reduce lost items. Because the process is fully automated, you won't deal with human error.
What Does A Bar Code System Involve?
Basically, each item is assigned its own symbology. These are the lines that you see on packages that are scanned through a reader. Those lines are encoded with data about the product. Think about it in terms of when you go to the grocery store and the checker scans the products through the machine. We usually know them as UPC codes: Universal Product Code. Oddly enough this product code is also the most limited and most suited for the grocery industry. If you deal with a multitude of products you will want to check into the bar coding system that utilizes the 128 alphanumeric symbols called ASCII. Because of greater flexibility in ASCII coding, there are fewer readability issues.
A committee reviews and assigns codes for millions of product, so there are typically no problems with duplication. You will want to mitigate issues within your organization though by deleting obsolete products that are no longer in your inventory.
How to Collect Data?
There are several methods used for collecting and manipulating the data: scanning, touch screen, keypad, and voice input. The coding is tested for readability, so whether it is printed or badly deteriorated, you should still be able to scan and translate the information via the software provided.
Many companies will typically recoup the cost of installation within the first year of use, because it will mitigate loss and decrease inventory cost.
