Standards
To better enable the digital consumer and unlock business use cases, Canadian industries are embarking on one of the biggest changes since the original introduction of the linear barcode (1D) - the transition to 2D barcodes. 2D barcodes enabled by GS1 standards, such as GS1 DataMatrix, QR Code with GS1 Digital Link, and Data Matrix with GS1 Digital Link, have the capacity to encode more data than the current linear barcode. Examples of additional information that can be encoded are expiration date, batch / lot number, or URLs to product information (ingredients and allergen, etc.).
This transition journey will enhance the experience for consumers, brands, pharmacies, retailers, and everyone in between. GS1 is supporting the global industry to harness the power of 2D barcodes enabled by GS1 Standards to support new business solutions for today and in the future.
For additional information on Global Transition to 2D
2D barcodes use patterns of squares, hexagons, dots, and other shapes to encode data. Because the data is encoded in a two-dimensional pattern, 2D barcodes can hold more data than 1D barcodes while still appearing physically smaller.

GS1 DataMatrix is a standalone, two-dimensional matrix symbology that is made up of square modules arranged within a perimeter finder pattern. The GS1 DataMatrix uses Reed-Solomon error correction (four selectable levels of error correction are specified) and this feature helps correct for partially damaged symbols.

ALL approved applications.
ALL, some popular AIs:
Example:
GS1 Application Identifiers (AI) are used to share additional product information such as the item’s expiry date, and serial number and batch/lot number. There are 100+ GS1 application identifiers to select from.
As per Section 5.6.1 in GS1 General Specifications (External link opens in new tab.) some of the production processes that are used to produce GS1 DataMatrix symbols are:
* Dot Peen marking is a method of permanent marking, usually used on metal. It uses a stylus, or pin, which is fired into the marking surface to make an indented dot. By rapidly repeating this and moving the stylus between each dot, writing and images can be applied.

To construct a GS1 DataMatrix barcode you must first create the GTIN. To create the GTIN complete the steps 1 to 4 below:
QR Code is an International Standard ISO/IEC 18004. QR Code is only used by the GS1 system to encode the GS1 Digital Link URI syntax. Full technical aspects of QR Code, see ISO/IEC 18004 (External link opens in new tab.).
(GS1 Digital Link)
Data Matrix is an International Standard ISO/IEC 16022. It is only used by the GS1 system to encode the GS1 Digital Link URI syntax. Full technical aspects of Data Matrix, see ISO/IEC 16022 (External link opens in new tab.).

GS1 Digital Link (GS1 DL) provides the bridge needed to connect GS1-based identification schemes with the syntax used on the World Wide Web. In simple terms, GS1 DL provides a standard way of expressing GS1 keys and attribute data in a format that can be used on the Web.
A simple example: the GTIN 9506000134369 can, of course, be encoded in a 1D barcode thus: Using software, turn that GTIN into a Web address thus: https://id.gs1.org/01/9506000134369 (External link opens in new tab.) or https://dalgiardino.com/01/9506000134369 (External link opens in new tab.)
This example is three requirements in one:
The GS1 DL standard defines how to structure Web URIs to include further information (e.g., batch/lot, expiration date, serial number etc.) as well as other GS1 keys such as GLN (Global Location Number), SSCC (Serial Shipping Container Code) etc.
The GS1 Digital Link standard helps reinforce the One-barcode initiative and, the opportunity of using a single barcode to access digital information about the product is ensured.
The GS1 Digital Link standard extends the GS1 identifiers, such as the GTIN, to improved supply chain traceability information, business partner APIs, patient safety information and more.
Where a URL typically points to a single, specific website, GS1 Digital Link enables connections to all types of business-to-business and business-to-consumer information. This means the brand owner remains in complete control but can still link to any number of information sources and details, such as allergens, all from one symbol, saving space and improving efficiency.
A barcode or other data carriers can be made multi-functional by using GS1 Digital Link. It is important to arrange for links to be established from the identified trade item (product) to:
The smaller size of a 2D barcode reduces the amount of space required on product packaging, allowing more space for branding and product information. This smaller footprint also enables direct on-product marking of items where labels are not practical, such as surgical instruments, small cosmetics, cannabis products and medication e-leaflets.
2D barcodes are omnidirectional, meaning they can be scanned in any direction, saving time at checkout, dispensing and point of patient care.
Built-in Error Correction means 2D barcodes have a higher fault tolerance. This means that data can still be scanned if the barcode is partially damaged or torn, reducing transaction delays and disruptions at checkout, and increasing operational efficiencies and reliability.
Reduction in food, medical supply, and product waste: Visibility to expiration, best-before, and sell-by dates enables retailers, healthcare providers and other supply chain stakeholders to sell or promote soon-to-expire products first, reducing the volume of expired products being wasted. In addition to reducing waste and supporting effective inventory management and stock rotation, this helps reduce economic loss.
Increased patient and consumer safety: If a recalled product reaches the checkout or the patient care level, scanning the 2D barcode and using the data encoded within it can alert the person scanning that the item must not be sold or used. This prevents the use or sale of potentially harmful products. 2D barcodes can also support patient safety best practices, such as confirming right patient and right product at point of care.
2D barcodes facilitate smoother supply chain operations by maintaining first in first out (FIFO) to strengthen inventory accuracy, inventory availability, location insight and avoid waste by ensuring freshness through the usage of supplemental data, such as expiry date and lot number that is encoded in the barcode.
2D barcodes help ensure product authentication, enhance visibility of ingredient sourcing information, and build internal supply chain visibility. Having visibility to a product’s full chain of custody can give regulators and consumers added confidence that a product is authentic.
2D barcodes increase visibility to information required for sustainability initiatives, including sustainable sourcing, recycling information and more.
Encoding GS1 Digital Link in a 2D barcode, such as QR Code, provides an opportunity for brand owners to engage customers with additional product information that can influence purchase decisions and extend engagement post-purchase.
Providing visibility and access to more robust, accurate product information supports customer demands and increases trust between brands and their consumer.
