Physical to digital
GS1 identification keys enable the creation of globally unique identifiers, governed by strict management rules, to avoid that two physical entities would share the same digital identity.

These can be joined by application identifiers, batch numbers, location references and an indicator or extension indicator, depending on the type of code.
