1. A mobile device, comprising:
a contactless interface;
a secure element associated with the contactless interface,
wherein the secure element is configured to:
store a first contactless registry service (CRS) applet and a first applet within the secure element, wherein the first CRS applet is executable by the secure element to restrict communication of a first confidential information associated with the first applet via the contactless interface, wherein the first applet stores the first confidential information; and
store a second CRS applet and a second applet within the secure element, wherein the second CRS applet is executable by the secure element to restrict communication of a second confidential information associated with the second applet via the contactless interface, wherein the second applet stores the second confidential information;
wherein the mobile device further comprises:
a processor; and
a memory having program instructions stored therein that, when executed by the processor, cause the processor to:
receive a first request from a user to use the first applet;
in response to receiving the first request, select the first CRS applet, wherein selecting the first CRS applet further comprises instructing the secure element to execute the selected first CRS applet to cause communication of the first confidential information associated with the selected first CRS applet;
wherein the secure element is further configured to:
execute the first CRS applet;
execute the first applet; and
communicate the first confidential information stored in the first applet to an external system via the contactless interface for the first request.
