Google launches a new app ‘WifiNanScan App’ on Play Store that connects nearby devices without Bluetooth, Internet Connection.

Wi-Fi Aware — also known as Neighbor Awareness Networking (NAN) — allows Android 8.0+ devices to “discover and connect directly to each other without any other type of connectivity between them,” like an active internet connection. The APIs work to discover nearby devices and create network connections that can “share large amounts of data” or send short messages.

This might help for the following:

  • Securely send a document to a printer without first logging onto the network
  • View a restaurant menu and make a reservation while walking by without an internet connection, even when the restaurant is closed
  • Automate and timestamp school check-ins and roll-call
  • Streamline airport security, customs, and immigration processing flows using mobile identification (ID) such as a driver’s license or passport without requiring travelers to present a physical ID
