Beacon approach direction calculation method using the direction of the magnetic field. Access control system and payment system using this direction calculation method.

摘要

The present invention provides a beacon approach direction calculation method using a magnetic field, an access control system and a payment system using the same. It is a method for calculating the movement direction of a mobile phone without using GPS and a map. It is a method for calculating a movement direction by the reception intensity of a beacon signal and a direction obtained by a magnetic field sensor in the mobile terminal. The method facilitates the calculation of the movement type of the mobile terminal for the beacon in all places such as interior, basement, and a wave shadowing region. The payment system includes the beacon, the mobile terminal, and a POS terminal.
