eTicket - Đà Nẵng is a free Android application developed by Danang City under the Utilities & Tools category. The app's main feature is to issue and manage e-tickets for each household when going to the market. It helps facilitate a quick and convenient check-in process while keeping track of the shopping history of each household. It also supports quick contact tracing when needed.

The app's vision is to make e-tickets a new habit for people not only when going to the market but also when visiting crowded places such as hospitals, supermarkets, restaurants, bars, etc., during the pandemic. It aims to protect the community better, reduce the workload and resources of the government, and make the city safer and more civilized.

The app has three main functions: login, check-in, and statistics. Market managers use their accounts to log in to the app, and after logging in, a list of assigned markets will be displayed. By selecting the market currently being managed, managers can check-in households by scanning the QR code on their e-tickets. The app also provides statistics on the number of people who checked-in within the day or the last 30 minutes at the managed market.
