Abstract
A computer program product comprises computer usable program code for receiving data describing a proposed electronic transaction between first and second communications devices. Additional computer usable program code is provided for generating a first audio signal by sound detected by a first microphone of the first communications device, and for generating a second audio signal by sound detected by a second microphone that is part of the second communications device. Still further computer usable program code provides for authenticating that the first communications device and the second communications device are in the same proximity in response to determining that the first and second audio signals were produced by the same sound event, and for completing the proposed electronic transaction between the first and second communications device in response to authenticating that the first and second communications devices are in close proximity.
