When Declan Chan, a stylist based in Hong Kong, flew home from London this week, he was given a wristband to wear upon arrival.
It was an electronic band, and would track his movements while he stayed home for 14 days under mandatory quarantine, officials explained.
It's the latest preventative measure introduced in the city, which has seen a rise in imported coronavirus cases from overseas in the past two weeks, after a period of slowing infections.
The government announced new travel restrictions today, requiring all arriving travelers from foreign countries to undergo the 14-day quarantine. The wristbands, and an accompanying smartphone app, will alert officials if travelers violate the quarantine.
Chan said he was instructed to download the smartphone app, and to walk around his apartment once he arrived home, so that it could map his premises.
"So far, 5,000 reusable wristbands produced by the (technology) centre are readily available and another 60,000 disposable wristbands have been procured from the market, 5,000 of which were delivered and tested and the remaining 55,000 will be delivered in batches," said the government in a statement yesterday.
