<p>The present invention relates to an arrangement where a third party can effect control of access to an identification member (such as a SIM card) by introducing a further and/or different personal identification number (PIN) into the member and that is known either directly or indirectly to the third party only. In the example of a mobile phone a user generally inputs their PIN to effect control of the SIM card or phone. This PIN is checked against an approval flag either internally in the memory of the phone or at a remote site, and only if approved will the further PIN be provided to enable access by a user to the SIM card. This results in controlled access to the SIM that is controlled by a third party and not by the general network provider.</p> |
