1 Dimensional (1D) barcodes are represented by parallel black bars and numbers. 1D barcodes are what you typically think of when you hear the word barcode. George Laurer’s UPC codes, which are typically found in retail stores, are the most common type of a 1D barcode. 1D barcodes contain a small amount of data or information that can be extracted with the use of a barcode scanner. To be exact, according to Barcodes Inc, 1D barcodes can only hold between 20-25 characters of data.
The main benefit of 1D barcodes is that the scanners for 1D barcodes are less expensive than the alternative 2D barcode scanners. The reason for this is 2D barcode scanning technology is newer and therefore more expensive. If your organization does not need to hold a large amount of information within your barcodes, 1D barcodes are the most money-wise option. Another advantage is the overall performance of the 1D barcode scanner, as it generally performs faster, has a longer scanning range, and can scan without being affected by lighting.
2 Dimensional (2D) are barcodes that represent data in a matrix of contrasting cells. The most common 2D barcode is the QR code, which is heavily used for advertising and marketing purposes. However, 2D barcodes are used for much more than advertising. Unlike 1D barcodes, 2D barcodes can contain data vertically and horizontally, which allows the barcode to contain much more information than its processor. According to Barcodes Inc, 2D barcodes can contain 2000 characters or more. They are also able to link to websites, can be used for product tracking, product identification, and more.
One of the 2D barcode include being able to scan the barcode from any direction. This makes scanning quicker and more efficient. Another benefit is only needing to scan the barcode once to collect all information. With 2D barcodes, multiple fields in your inventory system can be populated at once, versus making multiple scans with 1D barcodes. This is especially beneficial for working within a warehouse, where hundreds of scans are made a day. Another benefit is that 2D scanners have the ability to reduce the use of counterfeit items, by improving tracking of items through the supply chain. 2D barcodes can carry much more information than the 1D barcode, making products more difficult to counterfeit.
