The TraceTogether Token facilitates contact tracing for COVID-19. The Token uses Bluetooth LE (Low Energy) to send and receive data. It transmits at a lower power than many consumer communications devices - such as mobile phones, Bluetooth headphones, speakers, and smart watches.

Today, there are strict limits on the transmission power of such devices based on international standards and the guidelines from the International Commission on Non-Ionizing Radiation Protection (ICNIRP), an independent international organisation recognised by the World Health Organization (WHO).

The TraceTogether Token has been tested by an independent laboratory, and is well within Singapore’s regulatory limits for short-range devices. It is safe for everyday use. From 17 May 2021, the TraceTogether Token or App is required to be used at venues that require SafeEntry check-ins.
