Abstract: In various embodiments, a content provider may provide interactive content that is a part of a social networking service. One or more frames may be embedded within the interactive content, where the one or more frames may be provided by a payment application. The payment application may be configured to enable a user to view a list of friends; enable the user to select (i) a fund amount and (ii) a friend from the list of friends to transfer the fund amount from the user to the friend; and communicate, by bypassing the content provider, with a payment host to transfer the fund amount from the user to the friend without additional information about the friend.

Abstract: The use of a mobile device with a merchant application may enable the merchant to turn the mobile device into a point-of-sale terminal that interfaces with a server. The server may receive from the mobile device a transaction via a network, in which the transaction includes transaction details for a purchase request made by a customer. In turn, the server may transmit a transaction token that identifies the transaction to the mobile device of the merchant. Subsequently, the server may receive the transaction token from a client device of the customer. The transaction token being transmitted from the mobile device to the client device using a short range communication that is independent of the network. After receiving the transaction token, the server may provide the transaction details of the transaction that matches the transaction token to the client device for display so that the customer may pay for the transaction.

Abstract: Disclosed are various embodiments for performing stateless verification of communication addresses. Encrypted verification data is generated for a user account, including a communication address and a first verification code, and a timestamp. The encrypted verification data is sent to a client, and the verification code is transmitted to the communication address. The encrypted verification data and a second verification code are received from the client. The communication address is verified in response to observing that the first verification code from the encrypted verification data matches the second verification code.

Abstract: A system for providing a user/child with the arrival status of a driver/parent and method therefore includes providing a mobile code carrier, a code reader that identifies a code stored on the code carrier, a processor communicatively coupled to the code reader, a memory communicatively coupled to the processor storing a data base that includes a data structure, and a plurality of displays each communicatively coupled to the processor and located in one of a plurality of disparate locations within a building. The method further includes identifying the code, associating the code with a target and at least one location within the building, and displaying to one of the plurality of displays where the target is located a message indicating that the driver/parent has arrived.

Abstract: Disclosed are various embodiments for performing stateless verification of communication addresses. Encrypted verification data is generated for a user, including a communication address, an identifier of the user, a verification code, and a timestamp. The encrypted verification data is sent to the user, and the verification code is transmitted to the communication address. The encrypted verification data and the verification code are received from the user. The communication address is verified based at least in part on the verification code received from the user and the encrypted verification data received from the user.
