What’s the Difference Between a Barcode and a QR Code?

Barcodes and QR codes both provide information electronically. Barcodes have been used commercially since the 1970s, while QR codes were developed in the 1990s. These technologies have both evolved and are now commonly used throughout the world. At first glance, barcodes and QR codes look very similar. So what’s the difference between a barcode and a QR code? Learn more here.

Different Appearance

Barcodes and QR codes look similar, but they have several major differences. Barcodes are composed of a pattern of black and white lines that represent information, while QR codes are composed of a two-dimensional matrix made up of multiple squares. A barcode can only contain a limited amount of information (about 25 characters’ worth), whereas a QR code can store much more data due to its larger size.

Different Purposes of Barcodes and QR Codes

Barcodes are mainly used to identify products in retail stores, online businesses, warehouses, and manufacturing facilities. They’re also used on library books and medical records. They provide a unique identifier for each item. Barcodes improve efficiency by making inventory more accurate and reducing errors in filling orders.

By contrast, QR codes can contain much more data, including website links, contact information, lists of ingredients, and more. Scanners are specifically designed to read QR codes quickly and accurately, making them an effective way to share links and other product or event data.

Why Would a Product Have Both a Barcode and a QR Code?

Some products may have both a barcode and a QR code. The barcode typically tracks the specific item in store inventory, while the QR code provides additional information, such as nutritional facts or product reviews. This helps customers make informed decisions about their purchases.

Barcodes and QR codes are two distinct technologies that serve different purposes. The differences between barcodes and QR codes complement each other. Barcodes help identify products, while QR codes store and share information quickly and easily. Both of these technologies continue to be prevalent in the modern world.
