Abstract
An identification device includes a portable key device which has a first memory device for storing an associated identifier and a projector device which is configured to project an optical code matrix, which is based on the identifier, as an image, and a lock device which is configured to detect the image of the optical code matrix projected by the projector device via a sensor device, and to carry out an image analysis of the detected image of the optical code matrix via an identification device, and on the basis thereof, to identify the portable key device with the aid of a comparison of the identifier analyzed from the optical code matrix with identifiers stored in a second memory device of the lock device.

An identification device, comprising:
- a portable key device having a first memory device for storing an associated identifier and a projector device to project an optical code matrix, which is based on the identifier, as an image;
- and
- a lock device to detect the image of the optical code matrix projected by the projector device via a sensor device, and to carry out an image analysis of the detected image of the optical code matrix via an identification device, and on the basis thereof, to identify the portable key device with the aid of a comparison of the identifier analyzed from the optical code matrix with identifiers stored in a second memory device of the lock device.
A portable key device, comprising:
- a first memory device for storing an associated identifier;
- and
- a projector device to project an optical code matrix, which is based on the identifier, as an image.
A lock device, comprising:
- a sensor device to detect a projected image of an optical code matrix;
- and
- an identification device to carry out an image analysis of the detected image of the optical code matrix;
- wherein the lock device is configured to identify a portable key device on the basis thereof with the aid of a comparison of the identifier analyzed from the optical code matrix with identifiers stored in a second memory device of the lock device.
A method for identifying a portable key device having a first memory device for storing an associated identifier and a projector device, the method comprising:
- projecting an optical code matrix, which is based on the identifier of the portable key device, as an image on a projection surface via the projector device;
- detecting the image of the optical code matrix projected by the projector device via a sensor device, and carrying out an image analysis of the detected image of the optical code matrix via an identification device;
- and
- identifying the portable key device with the aid of a comparison of the identifier analyzed from the optical code matrix with identifiers stored in a second memory device of the lock device.
