Abstract
When an online system receives an order from a customer, the online system can fulfill the order (for example, using a picker to acquire and deliver the ordered items) and use audio verification to verify delivery. When using audio verification, a customer or picker's mobile device plays verification audio including a verification code specific to the order. If the mobile devices (and, by proxy, the customer and picker) are nearby (for example, within 10 feet), the other party's mobile device can detect the verification audio through a microphone and decode the verification code from the captured audio. In some implementations, audio verification can also be performed using a smart doorbell or smart home without the presence of the customer.
