What is Audio QR technology, how it's work.complete information
With the help of Wi-Fi Bluetooth NFC, data will be all the data transfers, but how do you feel that friends should tell me that we can transfer data with the help of sound.
I am going to talk about audio QR or in general about transferring data with the help of ultra sonic frequency. You would think normal, how is it possible to transfer data with the help of sound sound? When we talk to anyone, it is the sound wave here, which transmits the data from one person to another. But let's talk to you for an electronic device so we work on it. The radio source for the microwave is Bluetooth or Wi-Fi, the bandwidth of the data is very much available here. The security here is too much but the range is too much but here we need We have a specialist hardware we have. Transmitters, receivers and then we are able to transfer data with the help of WiFi or Bluetooth.
But how good it is to be able to transfer data with the help of sound wave between two devices or two mobile phones. Inside each of our phones there is a speaker and a mic then this work will be done, but the problem comes to friends, if you think of transferring the data like this, then there will be no noise pollution or noise around here.

So to deal with this problem, we take on the work. Ultrasonic frequency refers to some such frequency, which is radio waves above 20000 Hz. We can not normally hear this man, but the speaker or mic is very easy to communicate with them. Transfer data between them, but the data rate which is the data rate is not so much and the bandwidth will not be so much, but still we can convey it at a short distance or at less signal. Here the meaning of the data is either on or off, or between two devices, in which a device is admitting ultrasonic frequency, or sending its pulse and the other device that is receiving the mic is receiving it. Meaning that he is receiving that pulse, he knows when it was zero and when it was one or the other, when it was on and when it was done and after that the complete data received receipt.
With the same technology, there is a TEZ APP launched by Google, which uses the same technology, which is called audio QR technology.
