Sound Wave

These are payment systems that use sound waves to connect smartphones with another device. Secure payments are

made over the cloud with the help of sound based technology and data is exchanged through smartphones’
microphones/speakers

How it Works Companies involved

White noise (transaction specific and valid for a few
minutes) generated by a Smartphone carries digital
information

Use Case

Vending machines, mobile top up, phone-to-phone
information transfer
Strengths

No personal or account data is stored in the sound
transmission
Weaknesses

Will likely support only small value payments
Security Risks

Stolen phone is the primary risk, offset by the fact
that these are small ticket transactions
