Abstract:
A method of managing priority in an electronic device, wherein the electronic device comprises a contact-less communication domain and a secure element domain, wherein the contact-less communication domain and the secure element domain are connected via a domain interface, and wherein the secure element domain comprises two or more interfaces. The method comprises: i) detecting (by the contact-less communication domain), a radio frequency (RF) field of an external device and, upon detecting said RF field or upon receiving a first command from the external device, ii) sending a priority request via the domain interface to the secure element domain; iii) receiving (by the secure element domain) the priority request and identifying whether the secure element domain is in a processing status, hereby iv) upon identifying that the secure element domain is not in a processing status, approving (by the secure element domain) the requested priority, and starting a transaction (by the contact-less communication domain) in a priority status; and v) upon identifying that the secure element domain is in a processing status, denying (by the secure element domain) the requested priority, and
starting a mute status or remaining in a mute status (by the contact-less communication domain), such that the external device cannot detect the contact-less communication domain.
starting a mute status or remaining in a mute status (by the contact-less communication domain), such that the external device cannot detect the contact-less communication domain.
