摘要

In order to calculate the moving direction of the portable terminal without using the GPS and the map, using the beacon installation direction information using the magnetic field of the place where the beacon is installed and the signal reception intensity value of the specific range, A method of calculating a beacon approach direction using a magnetic field that is easy to calculate a movement form of a portable terminal with respect to beacons at all places such as a room, a basement, and a shaded area by calculating a moving direction using a reception intensity value of a beacon signal, Access management and information providing and payment system.
