Barcode technologies provide fast reliable data collection to ensure part or product traceability, error-proof assembly processes, and enhance customer service.
Barcodes are machine readable symbols that store identifying data about the part or product with which they are associated. These symbols, when read by a barcode scanner, are decoded, recorded, and processed to extract the data for a variety of uses (e.g., pricing, order fulfillment, traceability through production, sortation, shipping, etc.).
A 1-D (one-dimensional) barcode is the typical style with which we are most familiar. All the information in the code is organized horizontally in bar and space widths and read left to right by a scanner. Several versions of 1-D codes store only numerical data while others can encode additional characters. The height of the code varies based on the space available on a product and the ability of a barcode reader to read a small or large sized barcode.
2-D symbologies are a more recent addition to the world of barcodes. By storing data both horizontally and vertically, significantly more can be encoded than is possible with a 1-D barcode. The following examples demonstrate the more popular ones available.
Over the years nearly every country in the world has developed their own postal codes to best suit their needs. However, in recent times there has been a move towards standardizing them.
Direct Part Marking (DPM) is a process to permanently mark manufactured parts without labels or packaging. DPM is often used by automotive, aerospace, and electronic manufacturers to ensure reliable tracking of their parts throughout their lifecycle. The preferred codes for DPM are the Data Matrix and QR Code.
