SafeEntry was a national check-in system which enables the logging of visitors at various locations during the COVID-19 pandemic in Singapore, allowing health authorities to track and isolate confirmed clusters. It was used in tandem with TraceTogether, the national contact tracing platform in Singapore. The system was deactivated on 9 February 2023 after authorities determined there was no longer a need for the system.

TraceTogether was a digital system implemented by the Government of Singapore to facilitate contact tracing efforts in response to the COVID-19 pandemic in Singapore. The main goal was a quick identification of persons who may have come into close contact with anyone who has tested positive for COVID-19. The system helps in identifying contacts such as strangers encountered in public one would not otherwise be able to identify or remember. Together with SafeEntry, it allows the identification of specific locations where a spread between close contacts may occur.
