SINGAPORE -- From Silicon Valley giants to Chinese internet powerhouses to local small and midsize enterprises, tech companies are finding business opportunities in coronavirus tracing apps that are being introduced by Asian governments as they secure safety from coronavirus infections while reopening their economies. On Friday Japan also launched an app developed by Microsoft.
Tracing apps take various forms, some using GPS to track potential infection cases and others adopting Bluetooth to record encounters. Some countries have developed the apps by themselves, such as Malaysia's MyTrace app, but private companies are involved in some government apps.
