The present disclosure is directed to a system and method for amplifying Radio Frequency (RF) signals. In some implementations, a system includes a first interface, a second interface, secure memory, a user-interface module, a processing module, and am amplification module. The first interface connects to a microSD slot of a mobile host device. The second interface includes an internal antenna for wirelessly communicating with retail terminals. The secure memory stores user credentials and a payment application used to execute financial transactions with the retail terminals. The processing module executes the payment application using the user credentials in response to at least a transaction request received by the RF module and transmits at least one transaction response to the retail terminal based, at least in part, on the executed payment application. The amplification module connected to a lead of the antenna and is configured to amplify at least received RF signals.

Amplifying radio frequency signals

The present disclosure is directed to a system and method for wirelessly executing financial transactions. A payment card includes an interface, a communication module, secure memory, a user-interface module, and a processing module. The interface connects to a slot of a mobile host device. The communication module wirelessly receives RF signals from and transmits RF signals to a retail terminal. The secure memory stores user credentials and a payment application used to execute financial transactions with the retail terminal. The user credentials and the payment application are associated with a financial institution. The user-interface module presents and receives information through the GUI of the mobile host device. The processing module executes the payment application using the user credentials in response to at least a transaction request received by the communication module and transmits a transaction response to the retail terminal based, at least in part, on the executed application.

Wirelessly executing financial transactions

The present disclosure is directed to a system and method for wirelessly communicating Radio Frequency (RF) signals. In some implementations, a microSD payment system includes an antenna element and a card element. The antenna element affixes to a surface of a mobile device and includes antenna for wireless communicating RF signals with retail terminals and a connection to a microSD card element. The card element includes a shape and dimensions approximately equal to a standard microSD card and wirelessly executes transactions with the retail terminals using the antenna of the antenna element.

Wireless communicating radio frequency signals

The present disclosure is directed to a system and method for using magnetically coupled antennas to enhance receptivity and/or reading range of radio frequency (RF) transaction devices. In some implementations, a method for boosting RF signals includes wirelessly receiving an RF signal from a transaction terminal at a passive antenna. The passive antenna is magnetically coupled to the antenna of a transaction card. The transaction card is inserted in a mobile host device and configured to execute a payment application using user credentials in response to at least a transaction request and transmits at least one transaction response to the transaction terminal based, at least in part, on the executed transaction application and using the antenna either standalone or through the coupled antenna configuration. The RF signal is transmitted to the transaction card using the inductive coupling with the terminal.

The present disclosure is directed to a system and method for wirelessly accessing broadband services using intelligent cards. In some implementations, a broadband service card includes a physical interface, a communication module, secure memory, and service module. The physical interface connects to a port of a consumer host device. The communication module wirelessly receives RF signals from and transmits RF signals to a wireless broadband network. The secure memory stores user credentials used to securely authenticate the card and access a service foreign to the consumer host device through the wireless broadband network independent of the consumer host device. The user credentials are associated with a broadband service provider. The service module accesses the foreign service using the user credentials in response to at least an event and transmits a service request to the broadband service provider using the wireless broadband core network.

The present disclosure is directed to a system and method for switching between internal and external antennas. In some implementations, a system includes an antenna, a connector, and a housing. The antenna is configured to communicate wirelessly transactions with transaction terminals. The connector is connected to the antenna and configured to connect a transaction card to the antenna in response to at least insertion in the housing. The housing enclosing at least a portion of the antenna and at least a portion of the connector and including one or more elements that form an opening for receiving the transaction card. In addition, the housing is substantially rectangular and includes a first portion with a first thickness and a second portion with a second thickness different from the first thickness and at least the thickness of the transaction card.

Switching between internal and external antennas

In some implementations, a method includes interfacing a mobile device including a GUI. User credentials used to execute transactions with contactless devices are securely stored and associated with one or more enterprises. The secure memory includes master credentials and a master security framework that enables enterprises to store or update user credentials and associated security frameworks. Displays associated with the user credentials are dynamically generated and presented through the GUI of the mobile device. Wireless transactions are executed with contactless devices using the selectable user credentials.

The present disclosure is directed to a system and method for selectively switching antennas of transaction cards. In some implementations, a method includes physically interfacing a card with a mobile host device including a Graphical User Interface (GUI). The card executes wireless financial transactions independent of the mobile host device. User credentials used to execute financial transactions with retail terminals are stored. Information is presented through the GUI of the mobile host device. An antenna of the card is selectively switched between an activate state and an inactive state in response to at least an event.

The present disclosure is directed to a system and method for updating mobile devices with additional elements. In some implementations, a cover for a mobile device includes side surfaces, a rear surface, a physical interface, and a circuit. The side surfaces and the rear surface are configured to be adjacent at least a portion one or more side surfaces of the mobile phone. The side surfaces and the rear surface form an opening that receives at least a portion of the mobile device. A first portion of at least one of the surfaces includes a connector for connecting to a port of the mobile phone. The physical interface includes in at least one of the surfaces that receives a memory device external to the mobile device. The circuit connects the physical interface to the connector.
