Abstract

Un système et une méthode d'activation d'outil comprennent la réception d'un code d'autorisation d'un utilisateur pour vérifier les droits d'accès d'un utilisateur à activer l'outil. Dans un exemple, le code d'autorisation est reçu d'une carte intelligente. L'environnement de l'outil qui peut être, par exemple, un puits de forage, est contrôlé. En réponse au code d'autorisation et au contrôle de l'environnement, l'activation de l'outil est validée.
