The Magic Keyboard with Touch ID sensor is a little cheaper right now on Amazon. Apple’s keyboard is sold for €120 instead of €159. This is the lowest price to date.
This is the compact version without a numeric keypad. To use the fingerprint sensor located in the upper right corner, you absolutely must have an Apple Silicon Mac (M1 or M2 family). If you have an Intel Mac, all the keys will be recognized, except for the Touch ID sensor – in this case, it is better to buy the version without Touch ID at 107 €.
The Magic Keyboard with Touch ID connects via Bluetooth or wired using the supplied USB-C to Lightning cable. Its battery is recharged using this same cable. The extended version with numeric keypad, which is not on sale, costs €185.
