QR codes vs. barcodes: Which is best for product labeling?
QR codes: Versatile and informative
QR codes are a type of 2D code that offers more complex data storage and can handle different types of data such as URLs and multimedia, making them useful for marketing and customer engagement.
Barcodes: a classic in retail
Barcodes are simple and cost-effective, ideal for basic tracking and inventory management.
Their linear format allows for quick scanning in checkout lines.
The choice depends on the application
Barcodes are ideal for simple tracking and inventory management, while 2D codes are better for storing larger amounts of data and security, as well as for interactive user experiences.

Function and use of the barcode
Barcodes are optical, machine-readable representations of data that have been used since the 1970s and revolutionized logistics and retail.
They store data by varying the width and spacing of parallel lines, enabling fast and efficient data collection.
A typical barcode consists of a quiet zone, start and stop characters, data characters and a check digit that ensures accurate scanning and data integrity.
Barcodes such as UPC (Universal Product Code) and EAN (European Article Number) are common in retail and postal services, where they are used to track goods and improve inventory management.
In addition, barcodes have become an indispensable part of manufacturing processes and logistics systems, ensuring that products can be tracked throughout the supply chain, from factory to customer.
QR code benefits and use
Developed in 1994 by Denso Wave, QR codes offer a two-dimensional data storage that can handle large amounts of information faster than traditional barcodes.
With four encoding modes (numeric, alphanumeric, byte/binary and Kanji), they can store different types of data, from URLs to multimedia and complex datasets.
QR codes are widely used in marketing to quickly and easily share information with customers, operations instructions to simplify complex procedures, and maintenance to provide detailed service information.
In addition, QR codes have become popular in the food industry to offer consumers transparency on the origin, manufacturing process and ingredients of products, improving traceability and transparency.
By integrating QR codes into various applications, businesses can improve the customer experience, increase engagement and offer more interactive and informative communication.
Examples of uses for QR codes and other 2D variants
Travel and transport
Airlines are using QR codes on electronic boarding passes, enabling passengers to check in online and receive a QR code on their mobile device.
SAS has introduced mobile boarding passes with QR codes, improving the passenger experience and reducing reliance on paper passes.
This technology also contributes to a faster and smoother throughput at security checks and boarding gates.
Asset tracking in manufacturing
Manufacturing companies use both barcodes and QR codes to track assets through the production process.
Volvo uses QR codes to track parts and assemblies in car production, ensuring accurate identification of parts, streamlining assembly processes and improving safety by providing detailed history of each component.
Training resources
Educational institutions and publishers are using QR codes in textbooks and training materials to give students access to complementary online resources, such as video tutorials, interactive exercises and additional reading material.
Liber Förlag has included QR codes in its textbooks, allowing students to scan codes with smartphones to access a variety of additional learning resources.
This integration of traditional and digital learning resources enriches the learning experience and facilitates a deeper understanding of complex topics.
Examples of uses of barcodes
Trade and retail
barcodes are used for fast and accurate pricing at checkout, efficient stock management and to track product information.
It also facilitates inventory and provides real-time data on sales.
By reducing manual errors, barcodes increase efficiency and improve the customer shopping experience.
Tracking in warehouses and logistics
Barcodes enable accurate tracking of goods throughout the logistics chain, from delivery to warehouse management and distribution.
It reduces losses and improves logistics flow by providing instant access to the history and location of each individual product.
Document management
Barcodes are used to identify and track documents electronically.
By assigning unique barcodes to each document or file, organizations can quickly and easily organize, search and recover information.
This reduces the risk of lost or misplaced documents and improves the efficiency of information management.
Optimizing efficiency or accessing more information?
Barcodes offer an effective inventory management solution by quickly and accurately recording product information, reducing errors and improving stock turnover.
They enable real-time tracking of sales and stock levels, helping to avoid overstocking and improve customer service by ensuring products are available when requested.
Barcodes are cost-effective, require minimal training and work with a variety of scanners, making them a reliable solution for many businesses.
QR codes enhance the customer experience by offering an interactive and information-rich experience.
They can carry more information than barcodes and be customized for different purposes, such as sharing product information, customer reviews and special offers.
For example, a QR code on a product package can link to a website with detailed descriptions and videos, or on restaurant menus provide quick access to nutritional information and allergens.
This increases customer trust and loyalty.
In the food and beverage industry, QR codes improve traceability and transparency by linking to information about the product’s origin, manufacturing process and ingredients.
This meets consumer demands for quality and safety, especially for health and environmentally conscious customers, strengthening customer relationships and market position.
To sum up
QR codes and barcodes both have their strengths depending on the application.
Barcodes are simple, cost-effective and ideal for quick scanning in retail and inventory management.
QR codes, with greater data capacity and versatility, are ideal for marketing and storing complex information.
QR codes are widely used in travel, asset tracking in manufacturing and educational resources, while barcodes dominate in commerce, logistics and document management.
The choice between them depends on the need for simplicity and cost-effectiveness versus the need to provide richer and more interactive information to customers. Read more about various labels here on Grafokett.
