Abstract: In an embodiment, a computer-implemented method for causing funds to be transferred between a first user and a second user of a payment transfer system includes receiving, from an application executing on a user device of the first user, a user input for a payment transfer. The user input includes an identifier associated with the second user and a payment amount. The method includes configuring a resource associated with the payment transfer system and accessible via an interactive interface element activatable at a user device of the second user. The resource is configured to initiate transfer of the payment amount. The method includes causing an electronic message associated with the payment transfer and the interactive interface element to be transmitted to the user device of the second user. The method includes, upon receiving an indication of an intent to effectuate the payment transfer, initiating a transfer of the payment amount.

Abstract: In certain embodiments, a method includes receiving, at a payment server via an application executing on a device of a user, a request to create a payment proxy identifier. The method includes associating, in a data store maintained by the payment server, the payment proxy identifier to a financial account associated with the user. The method includes generating a personalized interactive element for initiating a transaction to the financial account of the user. The method includes receiving an indication of an intent to transfer a value from a sender to the user. The indication is produced via interaction of a device associated with the sender with the personalized interactive element. The method includes, responsive to receiving the indication, identifying a financial account of the sender and initiating a transfer of the value between the financial account of the user and the financial account of the sender.

Abstract: A fluid sample extraction device is disclosed comprising a housing defining an internal fluid passage having a distal open end and a proximal open end and a porous medium within the fluid passage, between the distal open end and proximal open end. The porous medium, which may be glass, is configured to allow fluid flow in the fluid passage to flow around the porous medium, toward the proximal open end of the housing, when fluid is drawn from the distal open end toward the proximal open end, and to allow fluid in the fluid passage to flow toward the distal open end of the housing, through the porous medium when the fluid is forced toward the distal open end. The porous medium is also configured to capture nucleic acids in the porous medium from the fluid when fluid is forced through the porous medium. Devices and kits are also disclosed.

The method includes receiving, from a mobile device of a second user, a request to transfer funds to the first user. The method includes identifying the account of the first user by retrieving the information relating to the account of the first user from the database using the unique payment proxy included in the request. The method includes providing instructions to display a user interface on the mobile device of the second user to facilitate the transfer. The user interface is personalized for the first user.

Abstract: Embodiments disclosed in this specification include uploading instructions to a voice-recognition server, such that when the voice-recognition server identifies keywords in an audio stream, the voice recognition server can perform a payment transaction using a payment-service-system server. The systems and methods disclosed can receive payment requests at the payment-service-system server, which can then process the payment transaction using historical payment information and contact information associated with the payment-service-system user. The payment-service-system server can communicate notifications and confirmations to the voice-recognition server or to separate user computing devices. In this way, the payment-service-system server can process payment transactions between users using voice-controlled speakers.

The transaction may then be processed based on the account information and the background messages.

Abstract: In particular embodiments, a method of transferring money by use of a payment proxy includes receiving a notification of an intent to initiate a monetary transaction in a message entered by a user of a communication platform, identified based on a determination of a particular context associated with content of the message. The method includes parsing the message to identify a unique payment proxy associated with a financial account having a syntax that includes a currency indicator and a string of characters. The method includes identifying a recipient financial account associated with the unique payment proxy. The method includes identifying a sender financial account based on the particular context associated with the content of the user message. The method includes initiating a transfer of a payment amount between the sender financial account and the recipient financial account associated with the unique payment proxy in accordance with the monetary transaction.

Abstract: This disclosure describes, in part, systems and techniques for providing digital receipts that may include itemized, interactive, and/or modifiable information about a transaction, such as a purchase transaction between a customer and a merchant. In various examples, a resource locator may be associated with transaction data and/or payment data. Furthermore, the resource locator may be associated with a storage location at which the transaction data and/or the payment data may be stored. In various implementations, the resource locator may enable access retrieval of data stored in the storage location to facilitate provision of an itemized digital receipt. Additionally, or alternatively, the resource locator may enable access retrieval of data stored in the storage location to facilitate provision of a response to an item-level information request.

Abstract: Described is a technology for executing financial transactions, e.g., payment transfers, by enabling a sender to trigger a money transfer by specifying, in any communication message, a payment proxy having a particular syntax, the syntax including a currency indicator preceding one or more alphanumeric characters. The payment proxy having the syntax indicates an intent of the sender to transfer money to a recipient associated with that payment proxy. The technology can include systems and methods of transferring money by use of a payment proxy within the context of a forum (e.g., social networking platform, microblog, blog, application, etc.). Messages of users in the forum can be monitored to detect for any user's intent to transfer money to a recipient. For example, forum messages can be parsed to identify the syntax carried by a user input in a forum message.

Abstract: In some examples, methods and systems may process one or more payment transactions between a merchant and a customer by establishing a short-range communication channel between a first computing device associated with a first user a second computing device associated with a second user. The method includes receiving, while the first computing device is offline with respect to a payment processing system, a fund transfer request from the second computing device, where the fund transfer request includes a payment proxy of the second user, the payment proxy having the syntax of a monetary currency indicator preceding an alphanumeric character. The method includes sending the fund transfer request from the first computing device to payment processing system after the first computing device establishes network connectivity with the payment processing system using a long range communication network protocol. The payment processing system processes the request unless the request has been previously authorized.
