<Your App currently shows possible exposures based on your SafeEntry check-in/-out records from the last 14 days. We are working on showing in your App the possible exposures based on TraceTogether Bluetooth records too.>
TraceTogether and SafeEntry work together to increase the speed and accuracy of MOH’s contact tracing efforts. TraceTogether helps MOH identify people who were in close proximity with COVID-19 cases, while SafeEntry helps COVID-19 cases remember the places that they’ve been to so that MOH can spot potential clusters. If you were in close contact with a COVID-19 case, MOH will contact you to provide the relevant care advice.
More details on how possible exposures are determined
i) TraceTogether Bluetooth records
When a COVID-19 case shares their TraceTogether Bluetooth records with MOH to help with contact tracing, the records are securely decrypted and filtered for based on duration and signal strength, to identify those who had substantial contact with the COVID-19 case.
ii) SafeEntry check-in/-out records
Among your SafeEntry records across all modes (e.g. TraceTogether App, SingPass Mobile App, your phone’s camera, or scanning your NRIC/FIN barcode), those that match the locations visited by COVID-19 cases will be shown to you through the App. As there is minimal risk through transient contact of less than 5 minutes, this service will apply to individuals with an overlap of at least 5 minutes with the COVID-19 cases (see image below). You can read more about the SafeEntry location matching here.
