Abstract
The door opening method compares identifying reference elements arranged in an identical manner on at least a pair of removable supports or cards which process reading units and activate the opening mechanism to be controlled. The reference elements can be transparent tags disposed in a position which is different in each pair of cards. The reading units have photoelectric sensors which are activated by a light source placed between the cards to project light on the sensors through the tags. One of the cards is inserted in a reading unit through a slit accessable from the inside. The other card is inserted in a identical reading unit through a slit accessable from the outside. When both units read the same combination from both cards a signal is emitted for actuating the opening mechanism.
