Hi, we're here from Curiosity.com to help you get smarter in just a few minutes.

Today you learn about how in the future you might be able to transfer data through music.

You'll also learn about the world of possibilities for cell-sized

robots in the final edition of our Microscale Mondays mini-series. Let's let us

find some curiosity. Scientists have found a way to transfer data through music.

Imagine a world where you don't have to ask for the Wi-Fi password in hotels or cafes,

where instead the access data is transferred through music.

And no, it's not a jingle that spells out

password one, two, three, four, five. How did you do my password? A team of

researchers at E.T.H. Zurich recently developed a technology to store data using musical notes that the human

ear won't hear, but a smartphone can. This might sound like an existing wireless technology like

Bluetooth, which does use radio waves to transmit data between devices.

But Bluetooth can be finicky, and it only works if users pair their devices.

This new technology straight up uses sound.

And since every smartphone has a built-in microphone that can pick up audio data,

users could decode that data by doing something as simple as downloading an app that reads the right algorithm.

Companies have been experimenting with soundwave data transmission since 2009,

but the Zurich team stands apart because of their mission to integrate data into music

without affecting listening pleasure.

The scientists use notes at very high frequencies that the human ear can barely register
