Define what a useful scan means
A label scan is useful when its output supports the next desk decision. A neat-looking name is not enough if the unit or tracking reference belongs to a different parcel. Before a trial, list the fields your workflow needs and which are optional. Treat the scan as input for review rather than independent proof of identity or ownership. This article concerns evaluation of label capture, not carrier routing or the legal handling of mail.

Choose examples with known answers
Prepare fictional labels with clearly different sender and recipient blocks. Add a second example with two similar recipient names, a slightly angled label and a low-contrast print. Use the same physical examples when comparing devices. Avoid inventing an accuracy percentage from a handful of favorable scans. Your small set can identify a concrete failure; it cannot establish performance for every carrier, language or lighting condition.

Compare one field at a time
For each attempt, compare the captured recipient, location and package reference with your answer sheet. Record omitted fields separately from incorrect ones. Then ask whether the staff member noticed the error before saving or taking another action. Do not correct the answer sheet to match the software. If a field is outside the product’s documented scope, record that as a scope limit instead of counting a surprising output as a supported feature.

Test the decision after uncertainty
An unreadable character should produce an explicit question for the operator, not a guessed resident assignment. Ask the provider to show how staff correct a result, stop an intake or continue using an approved manual path. Verify those behaviors in the available version. Do not imply a confidence score, validation rule or automatic hold exists unless it is demonstrated. The test is whether the team can safely recognize and handle uncertainty.

Make repeatability visible
Repeat an example with the same device and lighting, then change one condition such as glare. Note the condition alongside the outcome. A second attempt that succeeds does not erase the first failure; both inform how staff should position a parcel or escalate an unclear label. Keep testing separate from live intake. NIST’s AI guidance highlights evaluation and human oversight; your local evidence still has to show what occurred in your particular use case.
Leave with a specific next step
A useful finding reads: “recipient captured correctly, unit unreadable, operator needed a manual lookup.” The next step is to test that lookup using the approved directory and fictional identities. Avoid “AI works” or “AI failed” as the entire conclusion. Retain only the test evidence you need, and use fictional labels so ordinary screenshots do not spread resident names or shipment details. Bring the findings back to the full trial decision.
