  • data carriers can also be hidden and, for example, attached to or under clothing without the interrogation or reading being disturbed thereby.
  • This abusive access can consist of listening to the code and thus experiencing it, abusive person monitoring, manipulating the code by changing or deleting it, or the code 2 to imitate or multiply in order to gain improper access, access or other rights to the belongings of the owner of the data carrier.
  • a known but complex method is to cryptologically advance the security code both in the data carrier and in the interrogation device.

  • the data carrier can only be queried if the authorized owner or owner of the data carrier expressly permits it or if he releases the data carrier for querying. If he does not do this, the means m reliably prevent the data carrier from being queried by radio. In this way, misuse of the data carrier is completely impossible, at least if the means are not released.

Abstract

L'invention vise à améliorer la sécurité d'un support de données interrogeable par radio pour assurer une protection contre une interrogation abusive. A cet effet, des éléments réglables à volonté sont placés sur le support de données et permettent d'empêcher ou d'autoriser la réception de signaux d'interrogation. Ces éléments peuvent être des éléments de protection contre les interférences radio, servant à assurer un blindage électromagnétique, ou des éléments de commutation pour mettre hors service le support de données.
