RadioTag is a radio transmitter designed to enhance information broadcasting in museums, cultural events and entertainment places, linking visitors and participants to sources of information distributed along a given trajectory, to augment their experience. The device has the power of a normal computer, is smaller than a palm and covers a range from 10m to 100m. RadioTags are ideal to guide tourists alongside attractions, simplifying the visiting experience and allowing them to go on at their own pace. RadioTag has a wider range than regular QR or listed information and also allows the use of multiple languages at the same time.
