Abstract

Systems, methods, computer programs, and devices are disclosed herein for partitioning the namespace of a secure element in contactless smart card devices and for writing application data in the secure element using requests from a software application outside the secure element. The secure element is a component of a contactless smart card incorporated into a contactless smart card device. A control software application resident in the same or a different secure element provides access types and access bits, for each access memory block of the secure element namespace, thereby portioning the namespace into different access types. Further, a software application outside the secure element manages the control software application by passing commands using a secure channel to the secure element, thereby enabling an end-user of the contactless smart card device or a remote computer to control the partitioning and use of software applications within the secure element.
