Various techniques are provided for carrying out peer-to-peer financial transactions using one or more electronic devices. In one embodiment, a request for payment is transmitted from a first device to a second device using a near field communication (NFC) interface. In response to the request, the second device may transmit payment information to the first device. The first device may select a crediting account and, using a suitable communication protocol, may communicate the received payment information and selected crediting account to one or more external financial servers configured to process and determine whether the payment may be authorized. If the payment is authorized, a payment may be credited to the selected crediting account. In a further embodiment, a device may include a camera configured to obtain an image of a payment instrument. The device may further include an application to extract payment information from the acquired image.

A mobile device includes a wireless transceiver, a host processor, a secure element (SE), and a near field communication (NFC) system having an NFC transceiver and an NFC controller implementing a contactless front end. The contactless front end routes a near field communication related to a payment transaction between the NFC system and the SE without going to or from the host processor. The contactless front end routes a near field communication not related to a payment transaction, but requiring a security function, between the NFC system and the SE without going to or from the host processor. The contactless front end routes a near field communication not related to a payment transaction, and not requiring a security function, between the NFC system and host processor without going to or from the SE.

A mass storage memory card adds functionality to host devices with which it is used. In addition to the ability to store large amounts of user files and protect them from unauthorized duplication, a mass storage device according to the present invention enables near field communications with a portable electronic device that otherwise does not have such functionality. In a preferred embodiment the mass storage device has a mother / daughter configuration wherein the daughter card is a fully functioning micro-SD card that can be used independently. The mother card can be accepted in an SD card slot and communicates via the SD protocol. Whether or not the daughter card is present in the mother card, a host with the mass storage device therein will be capable of near field communications. These communications can be peer to peer or can be used to purchase goods or services as a sort of electronic wallet. A controller of the device is also operable to coordinate, control, and safeguard the financial transactions made when using the device and host as an electronic wallet.

A system (211) and method (400) for reliable monitoring of secure applet events is provided. The system can include a Near Field Communication (NFC) modem (140) for communicating transaction events, a secure controller (200) for monitoring state transitions caused by the transaction events, and a mobile host (125) for receiving event notifications of the state transitions via an Applications Programming Interface. An NFC reader can send a Transaction Acknowledgement TACK (403) to the NFC modem to confirm a receipt of data associated with an applet event. An INFO message (405) can be included with the TACK for informing a user of secure contactless transaction status through a user interface (190) of the mobile host.
