The wearable device will be made in Vietnam, using GPS technology to monitor individuals either under centralized quarantine or self-isolation, the Ministry of Information and Communications announced on Sunday.
The electronic bracelet can send alerts if the wearer leaves the isolation area and is expected to be sold at 35 U.S. dollars. Its battery lasts for up to 30 days, as reported by VNE.
Such a digital bracelet has been applied in certain countries and territories, including South Korea and Hong Kong, as part of the government's effort to contain the novel virus.
Starting March 19, Hong Kong put all arriving passengers under a two-week quarantine and medical surveillance. All entrants were required to wear an electronic wristwatch, accompanied by a smartphone app, to enforce the self-quarantine measures.
Around 6,000 items have been distributed to entrants upon their arrival in Hong Kong.

In early 2020, the South Korean government also mandated the use of electronic bracelets to all people violating self-isolation regulations.
Experts have been giving the wearable device a high evaluation for its feasibility and effectiveness in improving quarantine and contact tracing capacity.
Instead of staying at quarantine centers for weeks, suspected coronavirus patients or entrants can sign up for self-isolation at home as long as they put on the digital bracelets 24 hours a day. Authorities can keep track of these people’s whereabouts without having to gather them physically.
However, many wearers have voiced concerns about it being intrusive and a breach of privacy.

Vietnam has been launching the homegrown contact tracing app called Bluezone since last August. The app has reportedly helped trace thousands of suspected infections and will offer the highest possible effect if 60 percent of Vietnamese adults use it.
According to epidemiologists, the old contact tracing methods still work with low infection risk. As the pandemic has become more complicated, more drastic measures, including the application of digital bracelets, must be adopted to enforce surveillance and curb cross-infections.
Vietnam on May 24 morning records 33 new local cases in Bac Giang, Hai Duong, and Da Nang. The national tally has reached 2,254 in 30 cities and provinces since the new wave started on April 27.
