In some examples, a computing device may receive, from a merchant application on a merchant device, an indication that a buyer has initiated a transaction to purchase an item from a merchant associated with the merchant device. A first fulfilment selection may initially be associated with the transaction. The computing device may determine an association of the buyer with a buyer account. A buyer device having a buyer application executable thereon may be associated with the buyer account. The computing device may send, to the buyer application, transaction information related to the transaction to enable the buyer to pay for the transaction via the buyer application and/or change the fulfilment selection for the transaction. The computing device may receive, from the buyer application, at least one of an indication of authorization of payment for the transaction or an indication of a change to the fulfilment selection.

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.

A method for contactless payment is disclosed. The method comprises, at a point of sale, initiating payment by transmitting a token from a first device to a second device using a speaker associated with a first device, and a microphone associated with the second device; transmitting the token from the second device to a payment server; authenticating the token by the payment server; and upon successful authentication of the token, determining with a payment server whether the authorize of the payment.

An audio signal control apparatus includes a sound input circuit, a sound output circuit, and a control circuit. The sound input circuit is configured to receive an ambient sound signal from a microphone that captures ambient sound. The sound output circuit is configured to generate an output sound signal and transmit the output sound signal to a speaker to generate sound based on the output sound signal. The control circuit is configured to determine characteristics of the ambient sound based on the ambient sound signal received by the sound input circuit, determine a frequency band of the sound to be generated by the speaker based on the characteristics of the ambient sound, and control the sound output circuit to generate an output sound signal corresponding to the sound of the determined frequency band.

Provided are embodiments for a computer-implemented method for interacting with a user by an automated response system supporting topic switching and information collection. The computer-implemented method includes receiving a plurality of utterances from the user by the automated response system, and analyzing the utterances to form a first topic thread and an information collection objective. The computer-implemented method also includes utilizing an information collection user interface to gather data to support the information collection objective, and providing responses to the user after the gathered data related to the first topic thread. Also provided are embodiments for a system and computer program product for implementing the techniques described herein.

A voice-based digital promotion system may include an intelligent personal assistant. The voice-based digital promotion system may also include a remote sever configured to receive a request for a digital promotion from a given user via the intelligent personal assistant and determine a corresponding retailer loyalty program associated with the given user. The remote server may also be configured to determine at least one digital promotion for the given user based upon the retailer loyalty program, and communicate the at least one digital promotion to the given user via the intelligent personal assistant.

A non-transitory computer-readable storage medium storing computer-readable program code executable by a processor to receive a transaction request from a user interface, and receive a user-identifier from the user interface, and the user-identifier associated with a user. The program code may be executable to send a first non-audible sound signal to initiate a multifactor authentication process during a first interval, and send a second non-audible sound signal during a second interval, where the second non-audible sound signal comprises a predetermined frequency pattern, associated with the user. The program code may also be executable to receive a third non-audible sound signal, where the third non-audible sound signal, at least in part, is utilized to determine whether to complete the transaction request or not. The first non-audible sound signal, the second non-audible sound signal, and the third non-audible sound signal may comprise a frequency greater than 15 kHz.

An authentication server computing device is provided. The authentication server computing device is configured to receive a transaction request from an audio interface device, generate a first audio file including a first audio transmission, wherein the first audio transmission includes a primary security artifact and at least one secondary security artifact and the primary security artifact is an encoding of a one-time password, store a reference data file including the first audio transmission, transmit the first audio file to a verified user computing device associated with the account identifier, receive a second audio file from the audio interface device, wherein the second audio file includes a second audio transmission, verify the second audio transmission by comparing the second audio transmission to the reference data file including the primary security artifact and the at least one secondary security artifact, and authorize the transaction based on verifying the second audio transmission.

Various embodiments of the present invention pertain to a method for pairing devices using near field communication and an electronic apparatus using the same. The electronic apparatus comprises: a first wireless communication module supporting first wireless communication; a second wireless communication module supporting second wireless communication; a memory; and a processor operatively connected to the first wireless communication module, the second wireless communication module and the memory, wherein the processor is set to: detect a tag of an external electronic apparatus via the first wireless communication module; transmit a first command for driving a designated application of the external electronic apparatus to the external electronic apparatus via the first wireless communication module; receive, via the first wireless communication module, Bluetooth address information of the external electronic apparatus corresponding to the driving of the designated application; and perform, via the second wireless communication module, pairing with the external electronic apparatus on the basis of the received Bluetooth address information, wherein the pairing is performed in a tagging manner instead of a scanning manner during the pairing of the electronic apparatus with the external electronic apparatus, to thereby intuitively select the external electronic apparatus to be paired and simply perform a pairing process. Various other embodiments are possible.

A method, a terminal, and a storage medium are provided for controlling a functional circuit. In the method, the terminal acquires sensor data information of a sensor. Further, the terminal wakes up the functional circuit in the terminal to receive an ultrasonic signal in response to determining that the acquired sensor data information meets a preset condition.
