A technology like this could be very useful for password management. You store the passwords in your phone, and transmit them to the computer you are at through sound. No passwords to sync, no need to have an encrypted cloud location. If using a 3.5 mm male-to-male audio cable rather than speakers, no one in the vicinity can overhear either.

- mongol 6y agoTrue, if something like that is in the vicinity, not good. But with a cable like suggested, you you make it harder. I am thinking in the workplace. Edit: Also, communication could be encrypted. The receiver could show a QR code with a one time key, which your phone recognizes and encrypts with.
- admax88q 6y agoIf you're going to use a cable, might as well just use usb so you have a real data connection.
- mongol 6y agoYes but it is not always ok (policywise) to attach USB devices to corporate equipment.
- m4rtink 6y agoNot to mention simple analog channels vs complex modern protocol. Eq. it's unlikely the computer will try to take over your mobile device over an analogue audio channel while there could be viable attacks over an USB connection.
