Define which signal means “code read” and which means “transaction saved” before deploying a tablet scanner. A beep, flash or displayed value may belong to the capture stage while the business operation is still pending.
Document three states
| State | Evidence to define |
|---|---|
| Captured | The decoded sample value is visible to the application |
| Accepted for processing | The app shows the intended job and pending operation |
| Committed | The business system confirms the saved transaction and its identifier |
Ask the app owner to make waiting and failed states understandable. Do not assign a universal meaning to an accessory's sound without its documentation and an application test.
Check a deliberate retry
In an approved test system, submit one harmless scan and use the app owner's method to simulate a delayed response. Observe what an operator sees before retrying, then inspect the final transaction count. Agree how duplicate submissions are recognized and recovered. A second click or scan should not be assumed safe simply because confirmation is slow.
The T1 page lists the current configuration without a Honeywell barcode scanner. Confirm capture hardware, feedback behavior and software transaction handling as separate requirements. Rugged enclosure protection does not establish duplicate prevention.
This is a proposed acceptance case; no scan acknowledgement or duplicate-handling performance is measured here. For the broader framework, use the scanner acceptance checklist. Send Phonemax your capture and application requirements.
