System and method for scanning a person before entry to a restricted access area

A system for scanning a person before access to a restricted access area, the system comprising:

• a surface onto which a person can walk;
• a metal detector configured to detect a metal object in the shoes worn by the person and/or a metal object located in a waist portion of the person;
• a position identifying mark indicating a specific position of said surface with respect to the metal detector;
• an indication device for providing instructions to the person, directly or through an assistant;
• and
• a processing device for controlling the indication device:
• wherein the metal detector is configured to perform a first scan on-the-fly when the person is walking on said surface and a second scan when the person stands at said position identifying mark, and wherein the processing device is configured for:
• a) prompting or allowing the person to walk towards the restricted area if the first scan of the person's shoes and/or of the waist portion of the person performed by the metal detector indicates a probability of a presence of metal lower than a first threshold;
• b) prompting the person to place his feet and/or himself at said position identifying mark if the first scan of the person's shoes indicates a probability of a presence of metal higher than the first threshold, in order to carry out, by means of the same metal detector, the second scan of said shoes and/or of said waist portion, or
• c) prompting or allowing the person to remove his shoes and/or remove objects from his waist portion if the first scan indicates a probability of a presence of metal higher than a second threshold, or if the second scan indicates a probability of a presence of metal in the shoes and/or in said waist region higher than a third threshold.
