The mobile application installed on a mobile device may be used to setup a prestaged transaction. When the mobile device is in the proximity to the kiosk to complete the prestaged transaction, a location of the mobile device may be verified using ambient sound recorded by a microphone of the mobile device. The ambient sound may be songs, tones, or ultrasonic sound played by a sound system near the kiosk. The recorded ambient sound may then be compared to expected audio from the sound system to determine whether the mobile device is in proximity to the kiosk. ## Claims ### Claim 1 A method, comprising: receiving, by one or more computing devices, from a user equipment (UE) device, a kiosk identifier obtained from scanning an image displayed on a kiosk using the UE device;
