Abstract
Methods and systems for maintaining a healthy building. In one example, an access card reader for controlling access to a secure area may comprise a card reader for reading an access card identifier from an access card presented by a user, a touchless thermal sensor for sensing a skin temperature of the user, a memory, and a controller operatively coupled to the card reader, the touchless thermal sensor and the memory. In response to a user presenting an access card to the card reader, the controller may be configured to store in the memory the access card identifier read by the card reader along with a corresponding skin temperature of the user. In another example, a system may be configured to perform contact tracing when an occupant has been identified as displaying signs of an illness.
