Abstract: A building system has an elevator system controlled by a controller system to move an elevator car between building floors, and a registration computer system communicatively coupled to the controller system. The registration computer system generates an activation (QR) code that a user requesting elevator service scans with a mobile communications device. The activation code encodes user information including access rights of the user in the building. A software application executable by the mobile communications device responds to the activation code by generating a graphical user interface with displayed content determined by the user information in the activation code. The software application generates an optical credential upon the user specifying the elevator service. A credential acquisition unit reads the optical credential from the mobile communications device, whereby the controller system causes the elevator system to perform the specified elevator service upon determining that the optical credential is valid.

Abstract: A building system, such as an elevator system, a physical access control system, or a combined elevator and physical access control system, has a controller system to control the building system to perform a building action, and a credential acquisition unit to acquire a credential presented by a user. The building system includes a camera system having a thermographic camera, which generates an infrared image of a face of the user, and an image processing system. The image processing system processes the infrared image to determine if the user's face shows a temperature value that is higher than a set threshold temperature value. The controller system enables or disables the building action as a function of the acquired user credential and the result signal.
