Near Sound Data Transfer (NSDT) is a sound-based mobile transaction technology developed and patented by Tagattitude since 2005. NSDT uses a one time password sent through the audio channel of a mobile device to create an electronic signature enabling secure transactions.[1] Because all mobile devices have an audio channel (speaker and microphone) built in this technology is compatible with all mobile phones in use worldwide.

Applications[edit]

NSDT is primarily used for mobile banking transactions through the mobile money platform Tagpay. It is also used to securely open doors and enable authentication on websites.
