The work that begins after a product barcode is printed

Printing a web address on a package creates an awkward mismatch: the package may stay in circulation while the page changes. GS1 Digital Link separates the product identifier from the resources a scan can lead to, giving businesses a way to maintain destinations without treating every page change as a packaging job.

The code is only the beginning of that arrangement. GS1's URI syntax represents its identifiers in web addresses; a conformant resolver connects those identifiers to related information or services.

Consider a simplified product-information example. A package carries a Digital Link address identifying a product. A request reaches a resolver, which directs it to an associated resource. If the business reorganizes its product pages, the resolver's destination can change while the address on the package remains usable.

This is an illustration of the mechanism, not a report about a particular retailer. The distinction matters: the label does not contain the changing page, and a successful scan does not establish the accuracy of whatever appears there.

One identifier, more than one useful destination

The resolver standard describes links with attributes including their relationship to the identified item, language and media type. It also defines a default response and ways to request a particular link type. Resolution can therefore mean more than one permanent redirect to a marketing homepage.

A consumer-facing page and another related resource can be associated with the same identifier. Whether a particular scan reaches either one depends on the resolver's links and the request—not on a printed square deciding what kind of person is holding the phone.

That creates an operational responsibility. As an editorial inference, a maintained identifier is only useful for this purpose if the domain, resolver and destinations keep working together. Updating a redirect can repair a moved page; it cannot repair incorrect product information.

A phone demonstration does not settle checkout compatibility

GS1 distinguishes GS1 DataMatrix from Data Matrix and QR Code carriers that use Digital Link URI syntax. A square barcode's appearance is not enough to identify its encoding or the systems able to interpret it.

Its guidance also says a one-dimensional retail barcode may still be required during the transition. Opening a page with a phone and identifying a product at a checkout are different tests.

For a business evaluating a supplier, the useful demonstration follows the whole route: which identifier is encoded, what the scanner understands, how the resolver chooses a resource, and who can maintain it after launch. The long-lived commitment begins where the attractive scan demo ends.
