• and
• means for establishing the wireless connection between the transmitter device and the receiver device in response to a determination that the authentication code has been transferred to the receiver device.

A non-transitory computer-readable storage medium storing computer-executable instructions, the stored computer-executable instructions configured to cause a transmitter device to:

• generate, at a transmitter device, one or more communication symbols, wherein the one or more communication symbols represent an authentication code configured to enable authentication of a wireless connection between the transmitter device and a receiver device;
• transfer the authentication code to the receiver device, wherein the transferring comprises:
• generate a magnetic field;
• and
• rotate the magnetic field around one or more axes to encode the one or more communication symbols;
• and
• establish the wireless connection between the transmitter device and the receiver device in response to a determination that the authentication code has been transferred to the receiver device.

A method for receiving data using magnetic communication, comprising:
