From 17 May, when TT-only SE is implemented, check-ins via non-TT modes, such as scanning of identity cards, scanning of venue QR code with mobile phone camera, Singpass App or other QR code reader apps will be disabled. Venues should allow entry to individuals who have successfully performed SafeEntry check-in using their TT App or TT Token.
To prepare for implementation of TT-only SE, TT-only SE venues must be able to accept TT App and TT token check-ins. Venue operators can continue to use their existing SE QR code to facilitate TT App check-in. To allow for TT Token check-in, venues must have deployed the , or use the SEGW function found in the latest version of the SafeEntry (Business) App. Businesses may also scan the QR code on TT Token, either through a smartphone camera within the SafeEntry (Business) App, or through an external device (e.g. 2D scanners).
Before the commencement of TT-only SE, a new poster with updated SafeEntry check-in instructions (but with the venue QR code unchanged) will be sent to the venues’ business emails. Venues will also have to replace existing SafeEntry posters with these new ones
 This scanning mode can be implemented by downloading the SafeEntry (Business) mobile app or loading the browser version of the app available at “www.SafeEntry.gov.sg > Scan Visitor” (link is https://www.safeentry.gov.sg/scanner_login) on any smartphone. Venues with higher footfall may wish to use a laptop connected to an external 2D scanner.
