Abstract: A method conducted using a mobile device is disclosed. The mobile device comprises a contactless application including a bridging module, a computer readable medium comprising a contactless kernel, wherein the contactless kernel includes a transceiver interface coupled to a processor. The mobile device includes a contactless element coupled to the processor. The method includes receiving a trigger signal indicative of a transaction to be executed. In response to receiving the trigger signal, the contactless kernel transmits first data to the bridging module. The contactless kernel is operable in a first mode of communication. The bridging module transforms the first data in the first mode of communication to first data in a second mode of communication and passes the first data to the contactless element. The contactless element transmits the first data to a user device, and thereafter receives second data from the user device to execute the transaction.

Abstract: Embodiments of the invention relate to a technique for updating a device comprising a first and second applets implementing application code. The technique may include determining that the application code needs to be updated, generating a verification value, and sending the verification value and updated code for a function in the first applet. The updated code for the function can be stored in the second applet instead of the first applet, and the function maps of the applets can be updated to reflect the address of the updated function. The updated code can then be executed using the updated function maps to perform a process.

Abstract: Embodiments of the invention relate to a device comprising an updatable applet and a static applet. For some embodiments, a device is disclosed comprising a processor, one or more memories storing an updatable applet, and a static applet in communication with the updatable applet, wherein the device is configured to receive updates to the updatable applet. The updatable applet and static applet may be executed through an access control software element that may prevent unrestricted access between the applets.
