Abstract: A secure method of transferring profile data between computing devices, such as mobile telephones, utilizes ultrasonic waves having an ultrasonic codec that is transmitted from a transmitting computing device to a receiving computing device. This method may be utilized by computing devices made by different manufacturers and having different operating systems. Computing devices may be placed in proximity to each other to initiate the profile data transfer via ultrasonic waves. A transmitting mobile computing device may transmit the ultrasonic waves through a speaker on the mobile device or through an auxillary speaker. The receiving device may receive the ultrasonic codec through a microphone, such as on the mobile device or an auxiliary microphone. Each computing device may utilize an information exchanger software that enables the transfer of profile data through ultrasonic waves. A user may interace with the information exchanger software to transmit and/or receive profile information.
