Abstract

Communication between a software application midlet of a contactless payment device and a control applet resident within a secure element of the contactless payment device includes selecting, on the software application midlet, a card applet to configure from a registered list of card applets, the list comprising application identifiers (AIDs) of card applets resident in the secure element; transmitting, through a secure channel, to the control applet on the secure element, the selected card applet's AID and an instruction for a selected function to be performed on the selected card applet; invoking, by the control applet, process method function calls of a card runtime environment, wherein the process method function calls are defined by the card issuer or the card runtime environment for performing the selected function on the selected card applet; and rendering the process method function calls, thereby performing the selected function on the selected card applet.
