alacrity2D 1D QR Desktop Barcode Scanner, Omnidirectional Hands Free USB Wired Barcode Reader, Capture Codes on Screen, 3300DW, Black

Can this scanner scan a QR code either from a plastic card, from printed matter or from phone?

Where is the driver for the virtual usb com port (serial port) ? the user manual says for "windows system you need to download the driver"

does the scanner come off the base for wireless use?
