Researchers at Hong Kong Baptist University (HKBU) have integrated artificial intelligence (AI) technology with BU-Trace, the COVID-19 alert system (the System) they have developed.

The enhanced system also shortens users' check-in time at a venue to just one to two seconds by employing Near Field Communication (NFC) technology.
