Abstract
A service management system validates service on building management systems. Devices of the building management systems include wireless transmitters (for example, radiofrequency identification (RFID) tags) for transmitting wireless signals containing identification information. During service, a technician reads the identification information using a mobile computing device (for example, an RFID reader) while also recording the signal strength of the wireless signals. The mobile computing sends the identification information and signal strength information to a connected services system along with information about the service, and a validation module confirms that the identification information and signal strength information indicates that the technician was actually in the vicinity of the devices that were serviced.
