Bye-bye, barcode – keep track: What happens when the barcode disappears?

The switch to 2D codes such as GS1 DataMatrix and GS1 Digital Link in the QR code has been decided and marks a technological advance in product labeling. While the classic EAN barcode can continue to be used for simple applications for a transitional period, the new technologies offer expanded possibilities for transparency, traceability and consumer interaction. However, this requires investment in new hardware and software as well as training for employees in POS and WMS systems.

The Sunrise 2027 project also introduced new terms that, understandably, were often confused, confused or misinterpreted in media reporting due to a lack of background knowledge. In this article we would like to provide clarity, clear up existing uncertainties and show that everything is much simpler than it seems at first glance.

• Important information for logistics: Sunrise 2027, the Data Matrix code (2D barcode) or QR code will replace the barcode

The introduction of new barcode technologies such as GS1 DataMatrix and GS1 Digital Link in the QR code brings significant changes to retail point of sale (POS) and warehouse management systems (WMS). Here is an overview of the three variants and their effects:

The three barcode variants at a glance

The three barcode variants at a glance

1. EAN barcode (1D barcode):

• The classic one-dimensional barcode (e.g. EAN-13) only encodes the GTIN (Global Trade Item Number), which is used to identify a product.
• It is widely used, but limited in terms of the amount of data that can be displayed and the flexibility.

2. GS1 DataMatrix (2D barcode):

• A two-dimensional code that can store additional information such as expiration date, batch number or serial number.
• Particularly suitable for goods and pallet identification as well as traceability in the supply chain.
• Requires specialized scanners and software updates to process the expanded data.

3. GS1 Digital Link in QR code

• Connects physical products to the digital world through web-enabled URIs (Uniform Resource Identifiers).
• Enables dynamic content such as product information, marketing campaigns or legal notices that can be updated at any time.
• QR codes can be printed smaller than classic barcodes and offer more space on packaging.

Changes at the point of sale (POS)

Hardware updates

POS systems need to switch to optical scanners that can read both 1D and 2D codes. A transition phase is expected by the end of 2027 in which both types of code will be used in parallel.

Increased efficiency

2D codes enable faster and more precise scans because they contain more data and have built-in error corrections.

Customer experience

QR codes with GS1 Digital Link give consumers access to additional information such as allergens, recipes or sustainability data directly from their smartphone.

Changes in Warehouse Management Systems (WMS)

Data integration

GS1 DataMatrix enables more detailed capture of product information such as batch or serial numbers. This improves traceability and inventory accuracy.

automation

The ability to capture multiple data points in a single scan reduces manual entry and minimizes errors.

flexibility

Dynamic QR codes can be used for different purposes, e.g. B. to track products along the supply chain or to manage recalls.

The difference between the commonly known QR code and the GS1 Digital Link in the QR code

The GS1 Digital Link is a standard that encodes information in a structured QR code so that it can be used equally by machines (scanners) and people (with smartphones).

The GS1 Digital Link uses the QR code as a carrier format, but not every QR code automatically contains a GS1 Digital Link. It depends on whether the encoded information follows GS1 standards, which include, for example, URLs to provide product specifications, tracking information or other data.

Suitable for:

• The GS1 Digital Link in the QR code can also be used for augmented reality with WebAR or WebXR for 3D product presentations!

Why will the barcode we are familiar with no longer exist in the future?

The reason for this is the increased need for information: both consumers and companies need more and more information about products directly on the packaging. These include, for example, the expiry date, batch or serial numbers as well as Internet links to ingredients, allergen information, sustainability aspects, product images and videos or consumer reviews.

2D codes, such as QR codes or the GS1 DataMatrix, offer the necessary information capacity and thus meet the new requirements.

The three defined GS1 standards

There are different versions of 2D codes, with three variants defined according to the GS1 standards. Two of them are already in use: the GS1 DataMatrix and the QR code in combination with the GS1 Digital Link. The latter enables access to further information on the Internet. The third variant, the Data Matrix with GS1 Digital Link (center of the picture), is still in the testing phase; No pilot projects are known yet.

The term 2D matrix code

It serves as a generic term for the QR code, the DataMatrix code and other similar formats.

2D matrix code is a general category of machine-readable codes that store data in a two-dimensional grid (matrix). These codes can store more information in a smaller space than traditional barcodes. There are several types of 2D matrix codes including:

Main types of 2D matrix codes:

1. QR code (Quick Response Code)

• Widely used for marketing, product information and mobile applications.
• Supports links, text, contact information, etc.

2. DataMatrix code

• Particularly often used in industry and medical technology.
• Small and efficient, ideal for small products or labels.

3. Aztec Code

• Used primarily in transportation (e.g. tickets, boarding passes).
• Does not need a “silent area” (white border) around the code.

4. PDF417

• A stackable 2D code that can store larger amounts of data.
• Often in official documents such as ID cards or airline tickets.

5. MaxiCode

• Especially for logistics, e.g. B. with parcel services (FedEx, UPS).
• Can also be read while scanning while moving.

Properties of a 2D matrix code

• Can encode alphanumeric characters, binary data and special characters.
• Is error-resistant, meaning it is often still readable even if damaged.
• Supports various applications, e.g. E.g. product tracking, mobile payments or authentication.

Differences to 1D barcodes

• 1D barcodes (e.g. EAN, UPC) only store data linearly (in one dimension).
• 2D matrix codes store data in two dimensions (horizontal and vertical) and therefore offer significantly higher capacity.
