Abstract: Conducting hands-free transactions comprises a server at a payment processing system, a user computing device, and a merchant computing device. The payment processing system receives a communication from a hands-free payment application on a user device, the communication comprising a first transaction token, an identification of a user account, and a beacon identifier. The merchant may provide a challenge to the user and use the response to identify the token and account of the user. The merchant computing device can use voice patterns of the user to assist in identifying the token and account of the user. The system receives from the merchant computing device a transaction request, the transaction request comprising the first transaction token and transaction data associated with the transaction request. The system determines that the transaction is for an amount less than a configured transaction limit and communicates a request for an authorization of the transaction.

Abstract: An account management system establishes an account for a user. The user enters user account information into the account and the account management system establishes a facial template for the user based on an image of the face of the user. The user requests to change user account information at a merchant POS (POS) device. The merchant POS device captures a facial image of the user and transmits the image the account management system, which generates a facial template and compares the generated facial template against the existing facial template associated with user account. If the generated facial template is less than a threshold difference from the existing facial template, the user may update user account information at the merchant POS device, which communicates the updated user account information to the account management system. The account management system associates the updated user account information with the user account.

Abstract: Conducting hands-free transactions comprises a server at a payment processing system, a user computing device, and a merchant computing device. The payment processing system registers a merchant system as a hands-free payment participant and provides a beacon identifier. The payment processing system receives a communication from a hands- free payment application on a user computing device, the communication comprising a transaction token, an identification of a user account, and the beacon identifier received by the user computing device via a wireless communication from a device associated with the merchant system and transmits the transaction token to the merchant system computing device.

Abstract: A user enters a location with a user device. A beacon device broadcasts a first beacon device code comprising a hardware identifier via a local wireless network at the location. A service application of the user device receives the first beacon device hardware identifier, logs a check-in status of the user, and transmits the check-in status to a service provider system. The beacon device generates, after a predetermined period of time, a subsequent beacon device code comprising a random number to broadcast at the location via the local wireless network. In response to receiving the subsequent beacon device code broadcast by the beacon device, the user device logs and transmits a subsequent check in status to the service provider system via the network. The service provider system provides services to the user device or another device at the location in accordance with the check-in status of the user device.

Abstract: A processing system periodically configures a beacon code and random nonce to transmit to a beacon device at a location. Multiple users enter the location with associated user computing devices. The user computing devices retransmit the beacon code broadcasted by the beacon device to the processing system. A particular user initiates a transaction at a computing device at the location, which transmits to the processing system a request for account data and retransmits the beacon code and a random nonce. The processing system verifies the beacon code and random nonce and transmits, to the computing device at the location, user account identifiers associated with user computing devices that retransmitted the beacon code. The processing system receives a selection of the user identifier from the merchant point of sale device and transmits account information to the computing device at the location.

Abstract: The proposed solution in particular relates to a computer-implemented method to identify user computing device locations based on location data and beacon signal strength in which a user computing device receives a beacon signal comprising a beacon device identifier from a beacon device via a wireless network scan and determines that a second location of the user computing device is within a geofence boundary and is less than a predefined distance from a location of the beacon device based on a beacon signal strength of the beacon device. The beacon signal strength is based on at least one of the received beacon signal and further signals received from the beacon device via the wireless network scan.

Abstract: An account management system establishes a facial template for a user based on an image. The user computing device, signed into a payment application at the merchant location, receives an identifier from a merchant beacon device to transmit to the account management system, which transmits payment tokens based on payment account data and facial templates to the merchant POS device for each user signed in at the merchant location. The merchant POS device identifies the user by comparing a captured image of the user against the received facial templates and transmits the payment token to an issuer system. At a later time, the account management system receives, from a user computing device, a subsequent user image and generates a subsequent facial template. If the difference of the subsequent facial template is less than a threshold from the existing facial template, the subsequent facial template is associated with the user account.

Abstract: A service system establishes a facial template for a user based on a user image. The user signs into a service application via a user computing device, which receives an identifier from a beacon device to transmit to the account management system. The account management system transmits facial templates based on payment account data for each user signed in at the service system location and transmits facial templates to a service computing device. The service computing device compares a captured facial image of a user initiating a service request against the received facial templates to identify the user. The service computing device receives a token from the account management system for the identified user. The service computing device transmits transaction details and the token to an issuer system to process the transaction. The service computing device receives an approval of the transaction authorization request.

Abstract: A processing system periodically configures a beacon code and random nonce to transmit to a beacon device at a location. Multiple users enter the location with associated user computing devices and retransmit the beacon code broadcasted by the beacon device to the processing system. A computing device at the location transmits to the processing system a request for account data comprising a hardware identifier and retransmits the beacon code and a random nonce. The processing system verifies the request based on the beacon code and random nonce and transmits, to the computing device at the location, user account identifiers associated with user computing devices that retransmitted the beacon code. Within a threshold period of time, the processing system may verify a subsequent request from the computing device, even without receiving the beacon code and random nonce, if the request comprises the hardware identifier.

Abstract: A user enters a location with a user device. A beacon device broadcasts a first beacon device code comprising a hardware identifier via a local wireless network at the location. A service application of the user device receives the first beacon device hardware identifier, logs a check-in status of the user, and transmits the check-in status to a service provider system. The beacon device generates, after a predetermined period of time, a subsequent beacon device code comprising a random number to broadcast at the location via the local wireless network. In response to receiving the subsequent beacon device code broadcast by the beacon device, the user device logs and transmits a subsequent check in status to the service provider system via the network. The service provider system provides services to the user device or another device at the location in accordance with the check-in status of the user device.

Abstract: Techniques are provided for managing caches in a system with multiple caches that may contain different copies of the same data item. Specifically, techniques are provided for coordinating the write-to-disk operations performed on such data items to ensure that older versions of the data item are not written over newer versions, and to reduce the amount of processing required to recover after a failure. Various approaches are provided in which a master is used to coordinate with the multiple caches to cause a data item to be written to persistent storage. Techniques are also provided for transferring data items and locks associated with the data items from one node to another.

Abstract: A user signs into an application via a user computing device at a merchant system location. The user computing device receives an identifier from a beacon device at the location to transmit to an account management system. The account management system transmits facial templates to the merchant camera device for users who are signed in to the application in range of the merchant beacon device. The user approaches a point of sale device to purchase a restricted product or service. The merchant camera device compares a captured facial image against the received facial templates to identify the user. A merchant POS device operator, after determining that the user is eligible for the restricted product or service based on account information of the user, selects a payment account of the user. The merchant POS device transmits transaction details to the account management system, which processes the transaction with an issuer system.
