Point the camera at the QR on the part or its tag, or type the 12-character code printed under it.
The last character is a check symbol computed from the other eleven, so a misread code is rejected here before any lookup. Codes never use I, L, O or U.
ERPs and warehouse scanners do the same thing over the API: one call to POST /api/v1/trace/{code}/receive marks the part received and countersigns the pending transfer. API keys and examples.
