Audio-based exit detection and payment confirmation for computing devices

Abstract

Methods and systems for improved exit detection, payment confirmation, and payment authorization verification are provided. In one embodiment, a method is provided that includes transmitting an audio transmission that includes a unique identifier of a facility. The audio transmission may be transmitted to a computing device, which may transmit in response an audio transmission containing a unique identifier and a payment confirmation identifier. The payment confirmation identifier may be compared to a database of payment information and it may be determined that the payment confirmation identifier corresponds to a completed payment. It may further be determined that the user has completed a payment and is permitted to exit the facility.

Dependencies are inferred from the claim text.
