Wireless connectivity is an innovative technology that allows devices to communicate without cables with a computer or other devices. They can be powered by a classic battery (AA or AAA type) with long life, or by an integrated battery for practicality, but with less life. Battery life can also be further reduced by the presence of a backlight. The standard range of such a connection is 10 metres, but some devices can communicate over longer distances. This makes them ideal for laptops and for carrying around.

Bluetooth is a wireless technology designed to transfer data between devices over a relatively short distance. It is particularly popular for connecting headphones, mice, keyboards and other peripherals to computers, mobile phones or tablets.

USB-C is the latest version of the USB interface that brings many improvements, including faster data transfer speeds, a smaller and reversible connector design, and the ability to deliver higher power for charging devices.
