The minister said the Office of the Government Chief Information Officer is partnering with the University of Hong Kong, to allow the app's automatic recording of one's entry and exit times via Bluetooth devices installed at venues. Sit stressed that the Bluetooth devices will not collect signal information from smartphones.
The function is now being tested in the HKU campus, and that the authorities would put the function into testing at venues such as minibuses late this month.
So far, there have now been more than 700,000 downloads of the app and over 70,000 venues posted the QR code for the app.
Earlier, the government said people will need it to enter restaurants, business venues and government buildings, or leave their contact details with the businesses.
Meanwhile, authorities working with Hong Kong Baptist University are developing a new function that would enable the app to find out when people get out of a taxi through big data analysis and changes in motion and location for "better user experience", Sit added.
