Indoor navigation (navigation in indoor environment) presents a new challenge in the field of personal navigation systems. Although there are a lot of options how to create a navigation system, but only few of them satisfy the requirements of users in terms of accuracy. Systems based on Near Field Communication (NFC) technology provide accurate positioning also in indoor environment, where other navigation techniques (e.g. GNSS) are not available. The advancement of smartphones, wireless networking and NFC technologies have opened up a new solution of indoor navigation. This paper presents an NFC and OS Android based indoor positioning system developed and implemented at the Department of Surveying, Faculty of Civil Engineering SUT in Bratislava to help the students and the visitors. NFC technology allows quick and easy transfer of the information in the navigation system by contact of a mobile device and an NFC tag anywhere in the building.
