2. In USB mode, the scanner identifies itself as a USB Keyboard Wedge
peripheral. And the USB host is the Point of Sale system, which is
responsible for configuring the device and handling its input. When the
code is scanned, the QR code is sent to the USB host as a series of
key presses.
3. In Bluetooth mode, the scanner identifies itself using the Bluetooth HID
protocol as a keyboard. When the code is scanned, the QR code is sent
over the Bluetooth interface to the host device.
Note that of these three modes, serial and USB are hot swappable (i.e. can be
changed while the scanner is running). The Bluetooth, however, has one minute
to pair with a host after it has booted until the Bluetooth radio is shut down.
This is to prevent unwanted users from pairing with the device.
Once the QR code has been transferred from the scanner to the Point of Sale
system, the scanner resumes looking for QR codes, and once again glows in its
breathing pattern and completed the sales cycle.
