Make sure that the speaker of the device transmitting the audio signal ("transmitter") is as close as possible to the microphone of the device receiving the signal ("receiver"). Then do the following:

• On the receiver, open the web app to process the MP3 data file.
• On the transmitter, play the MP3 audio ("data") file that contains the information (or file) you want to transfer. Keep playing it for at least 5 seconds.
• On the receiver, press the "Record" button as soon as the MP3 audio starts playing.
• On the transmitter, press the "Stop" button after 5 seconds.
• On the receiver, press the "Stop" button immediately after pressing the "Stop" button on the transmitter.

The recorded data is automatically forwarded to the remote database server for further processing. The results will soon be displayed on the receiver screen.

Make sure that the screen of the device that displays the QR code ("transmitter") is as close as possible to the camera of the device that scans the code ("receiver"). Then do the following:

• On the receiver, open the web app to process the QR data file.
• On the transmitter, open a digital chip card that represents the QR data file. A digital chip card is a PNG image consisting of a header, showing the card name and cardholder name, and a QR code, which contains details that bring the card into direct correlation with the data stored on the remote database server.
• On the receiver, position the camera so that the QR code from the data file appears on the screen.

Once scanned, the data is automatically forwarded to the remote database server for further processing. The results will soon be displayed on the receiver screen.

Upload an MP3 data file, or a QR data file directly from your computer, tablet, smartphone or smartwatch to the remote database server for further processing. The results will soon be displayed on the screen of the device from which you are uploading the file.
