Universal Sound Payments

TagPay's contactless payment technology enables strong authentication and secure payments with any mobile device. NSDT™ makes mobile payments go viral.

Enabling universal payments through sound

NSDT turns any phone into a contactless payment device. The end-user can make contactless payments with any mobile phone, be it a feature phone or a smartphone, no matter the telecom operator. No changes are made to the hardware or software.

 

HOW TO MAKE A PAYMENT WITH NSDT™

The merchant enters the amount owed on his TP1600 app. The end-user then enters his phone number and secret code. The TagPay platform calls the end-user’s phone. The end-user takes the call and places the phone next to the merchant’s device. A one-time encrypted password is exchanged between the two devices and the transaction is complete.

 
 

By using the phone’s microphone as a captor and the standard mobile network channel as a transporter, NSDTsecures transactions between any phone and a variety of accepting devices (with the TP1600 app).
