Update: Starting on 26 April 2022, most venues no longer require check-ins. Only larger events with more than 500 participants at any one time, and certain nightlife establishments, require the public to check in with their TraceTogether App or Token for VDS checks. Venues that want to use the SafeEntry Gateway feature for VDS checks should set up the SafeEntry (Business) App. For more details, see this press release.
Businesses can integrate with SafeEntry through the SafeEntry-API. However, with TraceTogether-only SafeEntry, venues must ensure that everyone aged 7 and above in the group displays their TraceTogether App or TraceTogether Token. Only then should individuals be allowed entry.
