What it is
A printable QR code that opens a shipment's [Smart Link](/docs/smart-links). Put it on a packing slip, a shipping label, a return insert or a shelf tag — a scan takes the customer straight to live tracking.
`` https://trackjet.world/qr/7f4e45a8 # SVG (default) https://trackjet.world/qr/7f4e45a8?format=png # PNG ``
The path is the shipment's Smart Link code; the QR encodes the full https://trackjet.world/t/{code} URL.
Native generation
The QR is rendered on the server with no external service — it never calls a third-party QR API. SVG is crisp at any print size; PNG is convenient for templates that need a raster image. Both download cleanly (Content-Disposition).
It always points where the rest do
Because the QR encodes the same Smart Link the [email](/docs/branded-email) and [status page](/docs/status-embed) use, a scan, a click and an embed all land on the same live page for that shipment. There is no separate "QR destination" to keep in sync.
Air-cargo documents
The same renderer is available inside the Air-Cargo Document Builder, so a generated shipping document can carry a tracking QR without any extra integration.
