GS1 1QR is a smart, upgraded version of the traditional barcode that offers multiple functions in one simple scan. Built on GS1 Digital Link standard, GS1 Hong Kong’s “1QR” is a one-stop QR code platform comprising rich information such as product details, discount offers, sustainability info like eco-product packaging, ways to recycle and recycling locations, as well as traceability and authentication information.

When scanned at a retailer’s checkout, it works just like a traditional barcode, helping to quickly and accurately process the purchase. However, when scanned with a mobile device, GS1 1QR connects directly to GS1’s platform—no extra apps required. This gives consumers instant access to key product details such as the GTIN (Global Trade Item Number), expiration date, batch or lot number, and serial number, allowing them to verify the authenticity of the product with ease.

Beyond basic product information, GS1 1QR also supports access to Environmental, Social, and Governance (ESG) data. This includes insights into packaging materials, recycling instructions, and even initiatives like “naked shopping,” where products are sold without packaging to reduce waste. By combining retail functionality with rich, transparent product information, GS1 1QR helps businesses build trust and empowers consumers to make more informed, responsible choices.
