The operating condition of any facility directly affects occupant satisfaction. However, a facility's functions deteriorate with time. To extend the service life of constructed facilities, a well-tuned maintenance program is required [2, 10]. Facility functions are provided by the facilities themselves and their equipment. Both depend on continuous maintenance to maintain normal functions. Assigning an ID to each facility and apparatus is a regular way to manage them. Barcodes seem to be the most frequently employed system for acquiring the information. However, barcodes printed on paper are easily broken. In addition, obstacles between the barcode and laser scanner can interrupt optical communications. These problems limit their efficacy in facility maintenance [4, 7].
