A machine-readable matrix code that can link a battery or product to required digital information.
QR code is the machine-readable matrix code that links users, operators, or authorities to information required by the Battery Regulation. In battery-passport implementation, it is an access mechanism, not the passport itself; the underlying passport record, identifier, access permissions, and data model remain separate.
The EU Battery Regulation defines QR code as a machine-readable matrix code linking to information required by the Regulation. DIN DKE SPEC 99100 reinforces the implementation point that the QR code sits in the labelling/access layer and should not be confused with the passport record or the data model.

DIN DKE SPEC 99100:2025-02 — Requirements for data attributes of the battery passport
DIN DKE SPEC 99100 uses QR code as implementation context for the battery-passport labelling and access layer.

This term matters because the QR code is a practical access point for battery information, labels, and passport-style data. For battery passports, it should be managed as a data carrier connected to a unique identifier and passport record, with lifecycle durability and permissions considered.
QR code is often treated as shorthand for the passport itself, especially in label and packaging discussions. The code is only the visible access mechanism. If the evidence behind it is stale, incomplete, or linked to the wrong battery, the scan creates confidence without substance. For Minespider, QR code is an access-layer term connecting the physical battery to digital evidence, but the trust sits in the governed record behind the code.
