Businesses are constantly looking for faster and smarter ways to connect their physical products to the digital experience. This is where the QR Code vs Barcode Debate comes into play. Both QR codes and barcodes store information about a product; they both also allow businesses to scan that information into their system, but how they do each one is different and affects how the company operates, markets, and interacts with their customers differently.
QR codes are very popular now that people can use their smartphones as QR code scanners, and they are used all over the world, from product packaging to restaurant menus, event tickets, and more. Traditional barcodes are still important for inventory management and retail checkout. So, which is better for business, a QR code or a barcode, and how do you decide?
In this blog, we’ll break down the difference between QR codes and barcodes and explore QR codes vs barcodes for marketing. You will be able to make the best decision for your business by choosing between using either one or both to help you generate more business.
What Is a Barcode?
A barcode is a means by which a machine can read data through a graphic design usually made up of several parallel black bars with a variety of white spaces that are of varying widths. The barcode visually represents the codes that can be scanned to find out the details of a product, such as pricing, name, category, and other information stored in a computer database. By using barcodes, the fundamental part of every business process is simplified in areas such as inventory control, product tracking, and payment methods.
Understanding the Basic Barcode Structure
The barcode uses the variation in the gaps, widths, and heights of the bars to convey characters or letters. There is a "Quiet Zone" on either side of most barcodes that provides a buffer so when a barcode scanner scans the barcode, it can properly detect and read the code. In addition to the code itself, many barcodes have a number printed below the bar, which can be used for quick reference to identify the product by a human.
How Barcode Scanning Technology Works
An optical scanner reads the alternating dark and light areas in the barcode by using either a laser or imaging sensor. The alternating areas are then converted to digital data and compared with the product record in a database for fast identification and seamless checkout or tracking.
Different Types of Common Barcodes
1D (Linear) Barcodes:
A one-dimensional barcode has the information encoded in a single horizontal line. They are frequently used to identify retail and grocery items, as well as in inventory management systems. The most popular examples of one-dimensional barcodes are: UPC, EAN, and Code 128.
2D (Two-Dimensional) Barcodes:
Data can be encoded both horizontally and vertically in a 2D barcode, allowing the data contained in the barcode to be significantly larger than that which is found in its linear cousin. Shipping, asset tracking, digital ticketing, and other types of applications frequently use 2D barcodes. The most prominent example of a 2D barcode is a QR code.
Business Applications of Barcode Technology
Barcodes are used for many different types of industries, including retail, logistics, healthcare, manufacturing, warehousing, and event management. Barcodes allow businesses to track inventory, manage assets, label shipments, identify patients, tag equipment, and verify tickets.
What Is a QR Code?
QR code stands for Quick Response Code. A QR code is a two-dimensional barcode containing a large amount of data in an easy-to-scan square shape. A traditional barcode contains information only in a horizontal line, while QR codes have the advantage of storing information in both a horizontal and a vertical direction. This allows QR codes to have many different types of information contained within them, such as text, URL links, contact information, and payment information, etc. The convenience of being scanned and processed instantly using a smartphone QR code scanner allows businesses to use QR codes as a versatile tool.
Understanding the QR Code Structure
The QR code is comprised of black squares (modules) that are arranged to form a square grid pattern against a white background. The QR code contains key components that include finder, alignment, timing patterns, and the quiet zone, which ensures that the QR codes can be scanned correctly by devices. The QR code structure supports multiple data formats while allowing a quick scan time.
How QR Code Scanning Works
The free QR code scanner scans the QR code and converts the differences in color (black and white modules) into the data that has been encoded into the QR code. Thanks to the advanced error correction features built into QR codes, they can be scanned regardless of whether up to 30% of the QR code is damaged, smudged, or altered visually.
Types of QR Codes Explained
Static QR Codes:
Static QR codes will contain the same information as they did on the day they were created and therefore can’t be altered. Static QR codes will generally be used as a simple means of sharing information such as Wi-Fi passwords, contact information, or links to websites.
Dynamic QR Codes:
Dynamic QR codes have been created in such a way that they can have their content edited after being generated. Dynamic QR codes will also have additional features such as scan tracking capabilities, the ability to create analytical data, password protection, and short links to allow for easier use in marketing campaigns.
Real-World Uses of QR Code Technology
QR codes are used for many purposes (e.g., retail, hospitality, marketing, logistics, payment processing, health care, and education). Businesses use QR codes in digital menus, product packaging, event registrations, contactless payment, and collecting customer feedback. QR code generators are often used when businesses create their QR codes.
Key Differences Between QR Codes and Traditional Barcodes
QR codes and barcodes are two technologies that have similar functions, but the way they operate to accomplish those functions is very different. Barcodes have been used in retail and by warehouses to quickly scan and reliably track inventory for a long time; however, barcodes are limited to data that can be scanned from a single horizontal line. QR codes, however, have been designed with the digital world in mind; as such, QR codes can store a much larger volume of data (e.g., web addresses, payment information, marketing, etc.) than barcodes, and most smartphones are able to scan QR codes.
In addition to supporting visual customization, QR codes also provide businesses with access to trackable data analytics as well as error correction capabilities; therefore, businesses can use QR codes more flexibly for customer engagement and marketing. Recognizing these key differences allows businesses to select the best solution based on each business's goals, whether those goals be simple product tracking or developing an interactive user experience.
Advantages of Using Barcodes
Barcodes are an important component of the management of businesses and continue to be effective, like QR codes, as technology advances. When comparing QR codes and barcodes, barcodes outperform QR codes with respect to accuracy, speed, and cost-effectiveness (especially in a high-volume environment like retail, logistics, and warehouse operations). Because of their ability to automate the data collection process and provide a real-time view of inventory levels, barcodes are a vital component of any efficient and reliable organization.
