Abstract: A computer program product enables an advertisement audience dynamical detection circuit to conduct an advertisement audience quantity detecting operation. The advertisement audience quantity detecting operation includes: receiving a probe request frame transmitted from other wireless communication device; recording the arrival time of the probe request frame; inspecting the frame field configuration of the probe request frame; allocating the probe request to a corresponding data group according to the arrival time and frame field configuration of the probe request frame and a sequence control value in the header of the probe request frame while ensuring all probe request frames in the same data group have same frame field configuration; and calculating an estimated quantity of advertisement audiences passing through a specific location in a specific time period based on a total quantity of resulting data groups.

Abstract: A method for providing a loyalty program to a radiofrequency tag bearer includes during a purchase by the bearer, identifying said tag bearer by the public identifier from the radiofrequency tag thereof; correlating between the public identifier and database entries related to a buying history of the tag bearer; and determining a possible benefit to be given to the tag bearer on the basis of the entries corresponding to the public identifier. A network for implementing such a method and to a sales outlet integrating such a network are described.

Abstract: A method for communicating at least one targeted message from a service provider to a user of a portable terminal is provided. The terminal integrates a secure element including at least one information storage register and a system for enabling contactless communication of the secure element with a reader of the service provider. The method includes the creation of a user profile and the recording of same in the register of the secure element. The profile comprises personal data relating to the user with an associated confidentiality level. The method further includes, after identification of the user by contactless communication between his/her terminal and the reader, activation of the confidentiality level that the user accords to the service provider and the communication to the provider of the personal data corresponding to the activated confidentiality level. The personal data is processed to generate at least one targeted message which is communicated to the user.
