Abstract

La présente invention concerne un terminal d'informations qui est pourvu d'une unité de réception qui reçoit un identifiant en provenance d'un dispositif sans fil à courte portée lorsqu'il entre dans la zone de communication du dispositif sans fil à courte portée. Un dispositif de serveur est pourvu d'une unité d'acquisition qui acquiert, du terminal d'informations, l'identifiant ou un élément de travail correspondant à l'identifiant. Le terminal d'informations ou le dispositif de serveur est pourvu : d'une unité de détermination qui détermine l'élément de travail correspondant à chaque identifiant reçu d'une pluralité de dispositifs sans fil à courte portée par l'unité de réception ; d'une unité de stockage qui stocke la date à laquelle chaque identifiant a été reçu par l'unité de réception en association avec chaque élément de travail déterminé à l'aide de l'unité de détermination de sorte à être associés l'un à l'autre ; et d'une unité d'analyse qui analyse le temps de travail pour chaque élément de travail, la date étant associée à un premier élément de travail inclus dans les éléments de travail en tant que date de début du premier élément de travail et la date étant associée à un second élément de travail inclus dans les éléments de travail en tant que date de fin du premier élément de travail.
