A description of each pop-up alert and corresponding frequency throughout the investigated sample
| Pop-up message (colour) | Frequency as a percentage of serialised products entered into the study (n=2188) |
| Authenticated (purple symbol requiring no action) | 96% |
| Already authenticated here (amber) | Naturally occurring* |
| Authenticated elsewhere/falsified (amber) | 1% |
| Product recalled (red) | 1% |
| Pack recalled (red) | 1% |
| Pack expired (red) | 1% |
*If a medicine were scanned twice, the second scan would generate a pop-up which stated that the medicine was ‘Already authenticated here'. Therefore, these alerts were ‘Naturally occurring’ and not introduced by the principal investigator.
