SINGAPORE – The TraceTogether token is safe to use and transmits at a lower power than even mobile phones, said the Government on Saturday (May 15).
It was addressing a video making the rounds online this week suggesting that the token exposes a user to a high level of radiation, ahead of compulsory SafeEntry check-ins using the TraceTogether app or token from next Monday.
A post on Saturday morning on the Government’s fact-checking website, Factually, said that the token, which helps the authorities with Covid-19 contact tracing, uses Bluetooth low energy to send and receive data.
The token “transmits at a lower power than many consumer communications devices – such as mobile phones, Bluetooth headphones, speakers and smart watches”, said the post.
It added that the token has been tested by an independent laboratory and is “well within Singapore’s regulatory limits for short-range devices” and is “safe for everyday use”.
The post noted that there are strict limits on the transmission power of such devices, based on international standards and guidelines from the International Commission on Non-Ionising Radiation Protection.
The commission is an independent international organisation recognised by the World Health Organisation.
Earlier this week, a video clip surfaced online and on social media claiming to show the amount of electric and magnetic field emissions from the TraceTogether token.
The 2min 30sec clip shows a person using a radio-frequency meter to measure the amount of radiation from the token.
When he brings the meter over the token, the maximum and peak readings on the meter spike, although the average reading is much lower.
“Can you imagine that you are wearing this token… inside your pocket or somewhere near your chest?” he says, later advising viewers to keep the token away from their bodies as much as possible.
When he covers the token with a “shielding fabric” to show what people can do about the radiation, the meter’s peak and average readings fall although the maximum reading appears to be as high as before.
The clip does not compare readings for other electronic devices, such as mobile phones, with the token’s.
The Government Technology Agency (GovTech), which helped to develop the token, urged the public on Saturday not to be “misinformed by fake news”.
“There is no concern with the radiation emitted from the token,” it said on Facebook, reiterating points from the Factually post.
Meanwhile, GovTech said on May 7 that TraceTogether tokens have received the highest security label under a voluntary scheme that shows consumers how secure Internet-connected devices are against cyber-security threats.
The Cybersecurity Labelling scheme by the Cyber Security Agency of Singapore (CSA) has four rating levels. The highest Level 4 rating requires products to be sent for structured penetration tests conducted by CSA-approved third-party labs.
Tokens produced from Oct 13 last year will have the Level 4 label, including those made from April 1.
While the TraceTogether tokens are not technically Internet-connected devices, the Level 4 label “means that the tokens are secure by design”, said GovTech in a Facebook post.
“Data stored in the devices cannot be accessed by unauthorised parties, giving you greater peace of mind,” it added.
