QR codes are becoming an increasingly important part of product packaging. Once used mainly to direct shoppers to a website, these small two-dimensional barcodes can now connect a physical product with detailed information, instructions, promotions and supply-chain data.
For brands, this means a product label no longer has to be limited to the information that fits within its printed dimensions.
Turning Product Labels Into Digital Connections
Space is limited on most product labels. Companies need room for branding, product names, ingredients, directions, warnings, barcodes and other required information.
A QR code can connect customers to additional content without crowding the printed label. A shopper can scan the code with a smartphone and immediately access a digital page related to that specific product.
Brands are using QR codes to share:
-
Product instructions
-
Ingredient and allergen information
-
Nutrition details
-
Product demonstrations
-
Recipes and serving suggestions
-
Recycling instructions
-
Customer reviews
-
Promotions and coupons
-
Warranty registration
-
Product origin stories
-
Batch and traceability information
-
Social media pages
The printed label remains clean and readable while the connected page provides more room for detailed or frequently updated information.
One Label Can Provide Different Experiences
A traditional label remains the same after it is printed. A QR code can direct customers to online content that may be updated without reprinting the label, provided the destination address remains active.
A beverage company could link to seasonal recipes. A candle maker could provide safety and care instructions. A food producer could share information about ingredients, sourcing or suggested uses.
The experience can also change over time. A product launch page could later be updated with customer reviews, additional instructions or related products.
This flexibility gives brands another way to communicate with customers after a product leaves the store.
QR Codes Are Moving Beyond Marketing
Consumer engagement is only one part of the story. Retail and supply-chain organizations are also preparing for broader use of two-dimensional barcodes.
A traditional UPC identifies a product at checkout, but its one-dimensional format has limited data capacity. A two-dimensional barcode can carry more information and may support uses such as lot identification, expiration dates, recalls and inventory management.
GS1, the global standards organization behind many retail barcodes, is leading an industry initiative known as Sunrise 2027. The initiative calls for retail point-of-sale systems to be capable of processing certain two-dimensional barcodes by the end of 2027.
This does not mean every ordinary marketing QR code will automatically function as a retail barcode. Codes intended for checkout and supply-chain use must be created according to the appropriate standards and connected to valid product identification data.
What Is GS1 Digital Link?
GS1 Digital Link is a standard that connects a product’s GS1 identifiers to online information.
A QR code powered by GS1 can potentially serve several audiences. A consumer may scan it for product details, while a retailer or supply-chain partner may use the encoded information for identification, inventory or traceability.
Depending on how it is implemented, the connected information could include:
-
A Global Trade Item Number
-
Batch or lot information
-
Expiration dates
-
Product details
-
Allergen information
-
Recall notices
-
Recycling guidance
-
Digital manuals
-
Promotional content
GS1 describes the goal as moving toward a multipurpose two-dimensional barcode that can support both retail operations and consumer access to product information.
Why Consumers Scan Product QR Codes
A QR code is most useful when customers know what they will receive after scanning it.
A code placed on a label without an explanation may be ignored. A short call to action can make its purpose clear.
Examples include:
-
Scan for instructions
-
Scan for recipes
-
View product details
-
Learn about our ingredients
-
Register your product
-
Check recycling information
-
Watch how it works
-
Scan for a special offer
The destination should provide information that is genuinely useful and easy to view on a mobile device.
Good QR Code Design Matters
Adding a QR code to a product label requires more than placing a square graphic into the available space. The code needs to remain clear and scannable after printing and application.
Several design choices affect performance.
Provide Strong Contrast
A dark code on a light background is usually the safest choice. Low-contrast color combinations can make scanning less reliable.
Preserve the Quiet Zone
A QR code needs clear space around its outside edges. Text, borders, illustrations and other design elements should not extend into this area.
Avoid Printing It Too Small
A code that works on a computer screen may become difficult to scan when reduced and printed. The appropriate size depends on the amount of encoded information, printing quality, viewing distance and label surface.
Consider the Container
Curved bottles, narrow jars and flexible packaging can distort a QR code. Place the code where it will remain as flat and unobstructed as possible.
Use a High-Quality File
A sharp vector file is generally preferable when adding a QR code to label artwork. A low-resolution image may create rough or blurred edges that interfere with scanning.
Test the Printed Label
Always test the code using multiple phones and scanning apps. Testing should be performed on the finished printed label after it has been applied to the actual container.
Gloss and Matte Surfaces Can Affect Scanning
The finish of a label can influence how light reflects from its surface.
Gloss lamination creates more visible reflections. A QR code printed on a highly curved or glossy surface may need especially careful placement and lighting during testing.
Matte lamination produces less glare, but contrast, print quality and code size are still important.
Either finish can work when the QR code is designed, positioned and tested correctly.
Link to a Mobile-Friendly Destination
A successful scan is only the beginning. The linked page should load quickly and display properly on a smartphone.
Avoid sending customers to a desktop-only page or a generic homepage that requires them to search for the promised information.
A useful QR code destination should:
-
Load quickly
-
Work on mobile devices
-
Match the product
-
Clearly deliver the promised information
-
Use secure HTTPS
-
Avoid unnecessary forms or pop-ups
-
Remain available for the life of the product
Businesses should also avoid linking printed QR codes directly to temporary pages that may later be deleted.
Check Regulatory Requirements Separately
A QR code can supplement a product label, but it should not automatically be treated as a replacement for information that must legally appear on the physical package.
Labeling requirements vary by product, industry and location. Food, beverage, cosmetic, chemical and regulated products may have specific rules covering ingredients, warnings, nutrition information, identity statements and other disclosures.
Businesses should confirm the requirements that apply to their products before moving information from a printed label to a digital page.
The Product Label Is Becoming a Digital Gateway
QR codes are changing the role of product labels. A label can now provide more than a product name and basic information. It can connect customers, retailers and supply-chain partners to a much larger digital record.
The transition toward two-dimensional retail barcodes is likely to encourage more brands to examine how their packaging connects with online information.
The strongest implementations will not use QR codes simply because they are available. They will give customers a clear reason to scan, provide useful information and maintain a reliable digital experience after the product reaches the shelf.
