This is what you need to consider in the implementation
How complex the transition from barcode to 2D data carrier is depends largely on the individual circumstances, the objectives and the choice of product. For example, it is much easier to change the barcodes on a product where it is not integrated into the packaging layout but applied in the form of an adhesive label.
For a product like washing powder, where the EAN/UPC barcode has already been pre-printed on the empty packaging, the implementation is much more complicated. The only practical way would probably be to replace the barcode with GS1 DataMatrix codes that include a serial number in addition to the GS1 article number. In this way, the packaging can continue to be pre-printed, albeit with higher demands on the printing process and the filling process. In production, the packages are then filled as usual and the additional data is subsequently linked to the serial numbers in the ERP/PIM. However, this circumstance requires an exchange of master data at serial number level with the retail partners, who must then also be able to retrieve this data at all necessary points (such as the checkout environment).

FAQ - We are happy to answer your questions
We have compiled the most frequently asked questions about the changeover and their answers for you here. Contact us if the answer to your question is missing.
The Ambition Date 2027 from GS1 Global enables dual marking of 1D and 2D codes. Why is GS1 Switzerland's recommendation different?
Our recommendation is based on the current state of implemented PoS (point of sale) solutions among our users, feedback from our stakeholders on what they would like to see in an efficient transition phase, and practical considerations regarding the space required for dual labeling on products.
GS1 Switzerland recommends the use of GS1 DataMatrix for retail checkout sales. However, Ambition Date 2027 also allows other 2D codes approved by GS1.
The use of different GS1 2D codes in one application area should only be pursued if this creates added value for the user. From our perspective, this is not the case with the question of whether a GS1 DataMatrix or a GS1 QR code is used. Currently, in most checkout environments that can scan 2D code, QR codes are disabled. The reason for this is the pocket that today's QR codes of the manufacturers do not contain GTIN, therefore they are not used at the checkout and can interfere with the scanning process. Therefore, from today's perspective, the GS1 DataMatrix is much more suitable.
Can I switch directly to the QR code with GS1 Digital Link? This approach covers all my requirements.
This step is open to you. But the question is whether your partners in the supply chain can meet your request at this point in time. The complexity on the retailer's side is much higher if several data carriers have to be supported simultaneously at the points of sale.
If only GS1 DataMatrix is used in a sales channel, the retailer can ignore the QR codes on the products by not activating the QR code symbology at the checkout. GS1 DataMatrix codes also encode GS1 Application Identifiers (AI), which global retailers have been using in logistics for decades.
What are the first steps in the implementation?
Use the Blue Prints as a guide to estimate the issues you will be confronted with. Read the application recommendation "2D data carriers for fresh products" if you have to label fresh products. First discuss the various open questions in your company with the responsible persons.
How can GS1 Switzerland support me?
- You can use publications and use cases from GS1 Switzerland and GS1 Global for orientation.
- The Standards Expert Group offers you a platform for exchanging experiences.
- We are happy to support you in our system consulting or individually in the implementation.
