The method is for initiating a transaction. A communication device is in communication with a plurality of POS devices via a network and senses a magnetic field of a magnet. The communication device sends a turning off command to the first device to turn off the magnetic field of the magnet and checks whether a magnetic field still exists. When no magnetic field exist, the communication device determining that the communication device is in close proximity of magnet of the first device and initiating a transaction with the first device.
