![]() ![]() On the other hand, 1D barcodes are better suited to applications where information (such as pricing) changes regularly. The healthcare sector, with its focus on Unique Device Identification (UDI), is ideal for 2D barcodes. Unlike 1D barcodes, 2D barcodes don’t require access to an external database to reveal their meaning in other words, the information is stored within the barcode itself.ĢD barcodes can only be scanned by camera-based imaging scanners.ĢD barcodes are obviously smaller and “smarter” than 1D barcodes, but are best suited to applications requiring in-depth tracking information of a static nature. 2D barcodes are physically smaller than 1D barcodes, making them ideal for small electronic components, pharmaceuticals and medical devices. 2D barcodes use geometric patterns such as dots, rectangles, hexagons and squares to store data (see example below).ĭue to their two-dimensional design (data is encoded both vertically and horizontally), 2D barcodes can store significantly more information than 1D barcodes - including alphanumeric descriptions, images and website addresses. 1D barcodes rely upon access to an external database to reveal their meaning.ġD barcodes can be scanned by either camera-based imaging scanners or laser scanners.ĢD barcodes represent the next phase in barcode technology. The barcode itself is a unique combination of vertical lines and spaces which vary in thickness (see example below).ġD barcodes are generally limited to a few dozen characters - which limits the amount of data they can store. They’re the barcodes found on most popular consumer items. ![]() To gain an understanding of the two barcode technologies and their respective strengths, please read on!ġD barcodes are also called “linear” barcodes. But don’t write off the humble 1D barcode just yet. Yes, it’s true! 2D barcodes are smaller and “smarter” than 1D barcodes. ![]()
