The method comprises the steps of enabling a mobile electronic device of at least one member of the subscription group to use a short range wireless communication module to detect other mobile electronic devices. In response to detecting, the detecting mobile electronic device receives and stores a unique identifier for each detected other mobile electronic device. A processor compares each stored unique identifier with known unique identifiers of mobile electronic devices of members of said subscription group. As a consequence of the comparing step, the processor determines that two or more members of the subscription group are in close proximity to each other if at least one of the stored unique identifiers matches one of the known unique identifiers of mobile electronic devices of members of the subscription group.
