(ECNS) -- Professors at Hangzhou Dianzi University have designed a gadget to help avoid canteen crowding amid ongoing social distancing measures.
Students are suggested to scan a QR code after occupying a seat.
A mini-app, operated via Wechat, offers real-time info on empty spaces and dishes of the day.
The university has welcomed students back to campus in batches since the end of last month.
