QR codes

Practical guides for physical-object identity, labels, documentation and asset records.

Using QR codes for electrical documentation

A QR identifier can connect a physical panel with the latest digital record without crowding the label.

A persistent digital identity gives one physical object a stable place for identifiers, documents and history.

A simple introduction to persistent product records, identifiers and lifecycle data.

Decide deliberately which information anyone can see and which belongs behind account access.

CSV or JSON driven generation is useful when many labels share the same structure but different data.

QR and NFC can point to the same persistent object record, but they suit different physical workflows.

A public QR page should be useful to a scanner without exposing internal or sensitive asset information.

Keep permanent labels simple and move changing detail into the digital identity behind them.
