Abstract
A portable object for near field communication with an external reader able to provide a magnetic field. The object has no internal power supply or energy storage. It includes a near field communication module having at least one antenna and a microcontroller for managing the near field communication; and a support member in the form of a bracelet for receiving the antenna. The object is designed such that the antenna extends substantially along the bracelet-shaped support member, so that, when the object is within the incident magnetic field, the antenna, which is wound over the length of the support member, is at least partly exposed to the field irrespective of the orientation of the object in space. Also provided is an an antenna for a portable object.
