Ultrasonic payments

⚠️ This is not a real Stripe product ⚠️

I've been experimenting with ultrasonic data transmission in the context of ultrasonic payments. This repository contains a small demo sending a Stripe Payment Link between a merchant's transmitter device (e.g. tablet) and a customer's receiver (e.g. mobile phone).

It is relying on quiet.js and sends data via inaudible sounds.

If you want to try it out, play around with the live demo, and if you want to learn more, check out the blog post.
