How to adopt GS1 2D codes in commerce

Get ready for the next generation of barcodes

The global goal is that by 2027, point-of-sale terminals will be able to read both traditional EAN barcodes and 2D codes compliant with GS1 standards. GS1’s goal is to enable a smooth transition to the new generation of barcodes and ensure that retailers can take advantage of the opportunities it offers.

In addition to the product’s GTIN, a GS1 2D code can also contain other information, such as batch and date information. For the codes to function smoothly in everyday retail operations, implementation requires both technical capabilities and a decision regarding what information from the code the retailer wishes to utilise.

1. Make sure your POS terminals are capable of scanning 2D barcodes

Implementing GS1 2D codes requires that the store’s checkout terminals be capable of reading 2D codes. This may require software updates and, in some cases, hardware upgrades as well, if the current scanners are not 2D barcode scanners.

Determine whether the POS terminal scanners are 2D barcode scanners.
Ensure that the devices are configured to read 2D barcodes that comply with the GS1 standard.
Test the reading of 2D barcodes at the POS during actual sales transactions.

Who should you contact?

Your point-of-sale (POS) system provider
Your retail equipment supplier (barcode scanners and self-checkout system)

2. Decide what data from the GS1 2D code you want to use in your systems

A GS1 2D code contains at least a product identifier GTIN, such as an EAN barcode, as well as a web link. In addition, it may also contain other information, such as a batch number, date, or serial number. Before implementation, it is important to assess from a business perspective what data you want to read and store in your systems, and in which processes you will utilise it.

Point-of-sale functions and sales

Product identification at the register using GTINs
Targeting of promotions and discounts based on GTINs or batches

Date and waste wanagement

Utilising best-before/expiration date information to reduce waste
More precise targeting of date-based discounts
Improving inventory turnover (FIFO/FEFO)

Product safety and recalls

More precise targeting of recalls based on batch number
Preventing the sale of recalled products based on batch numbers

Receiving and inventory management

Scanning product batch and date information directly into systems
Better management of inventory balances and product-specific status

Consumer communication and digital services

Linking to product information from the loyalty app
New digital services from the packaging

Data and analytics

More accurate sales data at the batch or date level
Analysis of waste and recall data
Better identification of quality control issues and deviations

3. Make sure your systems are capable of processing the content of GS1 2D codes

In order for your company to utilise the data contained in a GS1 2D code, your POS system must be capable of both reading and correctly interpreting the GTIN contained within it.

And if you want to utilise other data from the GS1 2D code and also in systems other than your POS terminals, you must ensure that those systems are also capable of receiving, storing, and processing the data read from the GS1 2D code consistently throughout the entire process.

Ensure that the POS system can identify the product’s GTIN from the 2D code.
Decide whether the POS system will process only the GTIN or also the additional information contained in the GS1 2D code, such as the batch number, date information, and serial number.
Ensure that the checkout process is not disrupted even if a product has both an EAN barcode and a GS1 2D code during the transition period.
Test the scanning of 2D codes at the register and the transfer of data to the systems in real sales situations.

Who should you contact?

Your POS system provider (POS software and its settings)
Back-end system providers, if you wish to utilise the additional data contained in the code, for example, for loss prevention or traceability
