The keyboard can be connected with Bluetooth or with the included USB receiver.
Because the keyboard can be so wonderfully colourful and comes in well-known Logitech quality, it is a joy to use every day.

This one does support bluetooth.
Personally, I recommend using the USB stick and the lightning wireless mode (basically bluetooth). Very reliable (no connection lag, ever)

My French is non-existant, but I'm pretty sure both keyboards are identical.
