We would like to explain that for TraceTogether Token, similar to SafeEntry with NRIC, check-out is encouraged but not mandatory. We understand that some businesses and venues do not provide check-out options at their exits. In such instances, please be assured that locations that have not been checked out of for a prolonged duration will be cleared accordingly for contact tracing.
You may like to know that the Location Matching Self-Check (https://wereyouthere.safeentry.gov.sg/) is a service that helps members of the public recall if they had been at the locations visited by COVID-19 cases during the specified timings. This is done by checking against your SafeEntry check in records, if it’s within the 12 hour window period.
