clearing, by the computing device, the second executable code of the task from the instruction memory.

10. The method of claim 1 , the method further comprising:

loading, by the computing device, the data of the subtask into a portion of a data memory of the computing device according to the first executable code of the subtask, wherein the portion of the data memory is accessible by the subtask and the task; and

retrieving, by the computing device, the data of the subtask from the portion of the data memory according to the second executable code of the task.

11. A non-transitory computer-readable medium comprising a set of instructions that when executed by a computer processor, cause the computer processor to:

receive from a first server a subtask representing a virtual integrated circuit card (ICC), wherein the subtask representing the virtual ICC comprises data and first executable code configured to facilitate secure transactions;

store the subtask representing the virtual ICC in a non-transitory machine readable memory of the computing device;

receive from a second server a task comprising second executable code that instructs the processor to execute the first executable code of the subtask;

verify that maximum memory use of the subtask does not exceed maximum memory available for subtasks;

verify that the subtask meets one or more requirements imposed by the task;

verify that the task meets one or more requirements imposed by the subtask; and

execute the first executable code of the subtask responsive to verifying that the maximum memory use of the subtask does not exceed the maximum memory available for subtasks, that the subtask meets the one or more requirements imposed by the task, and that the task meets one or more requirements imposed by the subtask.

12. The non-transitory computer-readable medium of claim 11 , wherein to verify that the maximum memory use of the subtask does not exceed the maximum memory available for subtasks, the set of instructions cause the processor to compare a maximum memory use field of the subtask with a field of the task indicating a maximum amount of memory available for subtasks, wherein the maximum memory use field of the subtask indicates a maximum amount of memory the subtask needs to run.

13. The non-transitory computer-readable medium of claim 12 , wherein the field of the task indicating a maximum amount of memory available for subtasks indicates a maximum amount of memory available for subtasks, executable code of subtasks, and/or data of subtasks.

14. The non-transitory computer-readable medium of claim 11 , wherein to verify that the subtask meets one or more requirements imposed by the task, the set of instructions cause the processor to determine that a digital certificate of the subtask identifies the subtask as produced by a legitimate ICC developer.

15. The non-transitory computer-readable medium of claim 11 , wherein to verify that the task meets one or more requirements imposed by the subtask, the set of instructions cause the processor to determine that a digital certificate of the task identifies the task as associated with a bank or other financial institution.
