Proof a QR code on a wooden USB before approving the run

Decide where the code needs to live

A code on the drive remains with the device; a code on a box or insert may have more space and contrast. Choose the location according to the recipient’s task. Yousan’s wooden-drive guide compares these placements and emphasises testing the actual finished code.

If the code is only needed to explain the initial contents or order information, an insert may be practical. If it must remain useful after packaging is discarded, the drive needs a suitable dedicated area.

Protect clarity in the artwork

A QR code is a functional pattern, not simply a small logo. Keep its surrounding clear area free from adjacent text and decoration. Ask the supplier to check the proposed size against the chosen process and material. Grain, surface colour and the quality of the printed or engraved edges can affect readability.

Avoid choosing a universal minimum size from a generic guide. The actual encoded content, pattern density, process and expected scanning conditions need to be considered together.

Test the complete physical sample

Use the final intended destination or data when creating the sample. Test it with several representative phones under normal lighting and at the distance a recipient is likely to hold it. Check both whether it scans and whether it produces the intended result. A successful scan of a screen preview does not validate a mark made on wood.

Keep the destination maintainable

Confirm who controls the destination and how long it is expected to remain available. If a redirecting service is involved, understand the account and continuity requirements before printing. Record the approved code artwork alongside the housing and finish specification.

A sample test supports approval under the conditions checked. It should not be turned into a promise that every device, angle or lighting situation will work equally well.
