Abstract: A computing system can implement an automated peer-to-peer (P2P) transaction service in which digital wallets of users are linked with external accounts. The computing system provides a messaging engine that enables users to create chats in which underlying documents may be associated with a particular chat. The system can process information in the chat to automatic transaction triggers that cause the system to automatically execute wallet-to-wallet transfers between users.

Abstract: A computing system can provide a messaging service enabling a plurality of users to transmit and receive messages in connection with an automated peer-to-peer transaction service. The system can identify, within exchanged messages between a first user and a second user of the messaging service, a transaction trigger indicating a transaction request by the first user. Based on identifying the transaction trigger within the exchanged messages, the system automatically executes a transaction from a digital wallet of the second user to a digital wallet of the first user.

Abstract: A computing system can receive a primary authorization request from a merchant terminal of a merchant, the primary authorization request corresponding to use of a prepaid payment means of a user of the transaction service for a transaction with the merchant. Based on receiving the primary authorization request, the system can determine that an account balance of the prepaid payment means comprises inadequate funds to fulfill the transaction and automatically transmit a secondary authorization request to a financial entity associated with an account of the user. Upon receiving an approval of the secondary authorization request, the system can execute a transfer for a difference amount, based on an amount corresponding to the transaction, from the account of the user to an account associated with the merchant.

Abstract: A system receives a chat query based on a user interaction on a computing device of user. The system parses the chat query to identify one or more word patterns in the chat query, and determines a matching plug-in from the plug-in library based at least in part on the one or more word patterns in the chat query. The system utilizes the matching plug-in to access one or more resources and determine a chat response for the chat query, and transmit, over the one or more networks, the chat response to the computing device of the user.

Abstract: An interactive system can utilize microtechnology (e.g., a micro-electromechanical system (MEMS)), such as miniaturized microphone (e.g., a bone-conducting microphone), audio output device, microprocessor, and signal conversion and propagation means to create a personal area network (PAN) for a user.

Abstract: A computing system can receive a primary authorization request corresponding to use of a prepaid payment means of a user of a transaction service for a transaction with a merchant. Based on receiving the primary authorization request, that system can determine that an account balance corresponding to the prepaid payment means comprises inadequate funds to fulfill the transaction. In response, the system can automatically transmit a secondary authorization request to a financial entity associated with an account of the user, and subsequently receive an approval of the secondary authorization request, which enables the system to utilize the account of the user to make up for the inadequate funds of the account balance of the prepaid payment means.

Abstract: A computing system can receive a transaction data set from a computing device of a merchant, which can indicate a transaction between the merchant and a user of a network transaction service. The system verifies the user's location at a merchant location associated with the merchant, and then funds the transaction from a shared funding source of the network transaction service. Subsequently, the computing system can access a customer account of the user to reimburse the shared funding account for an amount corresponding to the transaction.
