First Claim
Patent Images
1. A mobile communication device capable of being secured when lost or stolen, the mobile communication device comprising:
- a memory device comprising a plurality of memory sectors, wherein at least one application is stored in at least one memory sector, wherein the memory sectors are protected against unauthorized access by sector keys; and
an applications manager configured to disable the stored applications remotely by Near Field Communication (NFC) when triggered by an external trigger event received from an external source, wherein the applications manager disables the stored applications by changing the sector keys.

Abstract
A mobile communication device (1) is connectable to a memory device (MIF) that comprises a plurality of memorysectors (0-F), wherein at least one application is stored in at least one memory sector. the memory sectors are protected against unauthorized access 5 by sector keys (key A, key B, 4). The mobile communication device (1) comprises an applications manager (MAM) being adapted to disable the stored applications (TK1, AC1, AC2, TR2, TR3, CP1, TR4, AC3, TK3) when triggered by an external trigger event.
