Abstract: In one embodiment, a method includes receiving a request from a client computing device to access an electronic GUI associated with a particular QR code scanned by the client computing device. The particular QR code is associated with at least a default GUI and a secure GUI corresponding to the particular QR code. The method includes determining whether a user associated with the requesting client computing device is authenticated to access the secure GUI corresponding to the particular QR code. When that user is authenticated to access the secure GUI, then the method includes selecting the secure GUI for presentation by the requesting client computing device. When the user associated with the requesting client computing device is not authenticated to access the secure GUI corresponding to the particular QR code, then the method includes selecting the default GUI for presentation by the requesting client computing device.
