Smart Technology for Security in Tourism Complexes

The technological development that is increasing daily in the world influences all sectors of the economy. One of the areas affected by this development is the tourism sector. Effective use of technological capabilities is an important issue in terms of providing the best service to customers and security in tourism. The aim of the paper is a conceptual study covering the application of smart technology for security in tourism complexes. In this work, a device has been created that transmits information secretly and safely through a red laser diode over a certain distance with minimal interference, which may be successfully used in complex tourism planning. The semiconductor laser diodes have been analyzed to optimize the investigated device's physical parameters. The advantages of semiconductor laser diodes, and their application areas, including secret transmission of information over long distances for the security purpose are presented, and also revealed their problems and limitations.
