Abstract: Mobile payments and processing data related to electronic transactions. A near field communication connection is established between a mobile communication device of a consumer that serves as a mobile wallet and an electronic payment device of a merchant. Authorization data is shared between the mobile communication device and the electronic payment device without providing electronic payment instrument (e.g. credit card) data to the merchant. Authorization data is transmitted from the mobile communication device to a cloud computer or resource that serves as a cloud wallet and hosts respective data of respective electronic payment instruments of respective consumers, and from the electronic payment device a payment processor computer. The payment processor computer presents the authorization data to the cloud wallet, and in response, the cloud wallet transmits the credit card data to the payment processor computer, which processes the transaction.

Abstract: During an update technique, an update for the software application is received from a provider of the software application. Then, update information is either received from the provider or is generated. This update information specifies an update relationship between the update and at least a previous version of the software application. Next, inventory information associated with a portable electronic device is accessed (such as whether the previous version of the software application is currently installed on the portable electronic device). In response to the accessed inventory information, an identifier associated with the update is dynamically generated, and the update and the dynamically generated identifier are provided to the portable electronic device. Using the dynamically generated identifier, an application management system or the operating system installed on the portable electronic device determines whether an update workflow is executed.

Abstract: A user registers with an automated transportation use and billing system. The user's geographical location/position is monitored and periodically compared with the geographical location/position of one or more public transportation systems. When a determination is made that the user's geographical location/position is the same as the geographical location/position of a public transportation system, an assumption is made that the user is making use of the public transportation system and once the user's geographical location/position data differs from the public transportation system's geographical location/position data, it is further assumed that the user is no longer making use of the public transportation system. Data indicating the users assumed use of the public transportation system, calculated as described above, is then recorded and credited to the user's account.

Abstract: During a financial technique, electronic devices may exchange, using a first communication technique, information with each other to establish a secure connection between the electronic devices when they are proximate to each other. After the secure connection is established, the electronic devices may hand off communication with each other from the first communication technique to a second communication technique that supports communication at a higher data rate and over longer distances than the first communication technique. Moreover, the electronic devices may communicate, using the second communication technique and the secure connection, additional information associated with the financial transaction with each other to facilitate completion of the financial transaction.

Abstract: During a transaction, an electronic device (such as a cellular telephone) captures a gesture performed by a user of the electronic device. This gesture is analyzed to determine salient features, such as accelerations of the electronic device during the gesture and associated time intervals. Then, the electronic device generates a token based on the salient features, and provides the token to a server. When a second token, associated with the token, is received by the server from a second electronic device, the server establishes a secure connection between the electronic device and the second electronic device.
