GateGoing Scan allows you to quickly open the scanner to scan a GateGoing QR code and enter that gate. When approaching a gate, you can quickly open this app, which is instantly ready to scan, just scan the QR code and you will visually get a signal if you are granted access. With GateGoing Scan, you can enter the gate in about 1-2 seconds, instead of 5-10 seconds. Think how much more work you could do with that time? This app doesn't replace the regular GateGoing app, it is a companion, and it can ONLY open QR enabled gates, for other types of gates, or to share gates, find public gates or create your own, you will still need GateGoing.
