According to Taipei Times, Minister Without Portfolio Audrey Tang (唐鳳), who led the team that created the new service, said that it was developed by activating the text-messaging function for the 1922 hotline, which was established by the Centers for Disease Control for people to ask questions about COVID-19 or other communicable diseases.
According to The China Post, starting today, Taiwan residents don’t need to fill Google Docs every time they head into a convenience store; instead, they can scan the QR code provided by the store and a text message will be sent to their phone.
In this way, the government can efficiently track your activity in case someone is infected and both customers and stores won’t have to pay for the text messages.
Taipei Times mentions, if people’s mobile phones do not have a QR code reader, they can instead manually type the venue’s identification code in an SMS and send it to 1922.
