Vanessa Or some smartphones.

Her father doesn't let her use it

Vanessa As long as the laptop includes it(not necessary the case),or with an external device.

I use external one. But for @Angelina to get familiar how it works in general

Vanessa he case in the hotel with the forgotten charger can still happen!

Seems you like this idea 😃 However NFC might be just a smartcard

          Ah?I did not remember it.

          I would hate if such thing would happen to me,but I find it funny.

          If we have to use an unusual thing,it is not much different than using a key..

                She shouldn't be able to unlock her belt without him, but he should. That's the different from using just a key

                    Laura

                    Hum,if he's the only one having the key,it is the case too...

                        Laura

                        I thought only of a card,not a 2FA thing.In this case,you're right.

                          I am more classical... I think that a padlock with a key is perfect for us.
                          Specially nowadays that there are plenty of models (mine are typical ones).

                            @Laura

                            I now roughly understand how it would work 😉

                            @Ines

                            i have to agree with you, it is (even if it is not positive for me) an intense feeling when i hear the clicking of the locks, i find it a bit strange to imagine something else. a cb is a conservative device and should therefore be closed conservatively

                              Angelina a cb is a conservative device and should therefore be closed conservatively

                              But the modern world is not so conservative. There are variety of lockpicking tools available to order online mentioned by @BikelockFugitive, 3D printers, etc. So shape of the key is not a strong secret anymore. In my opinion, digital electronic lock is inevitability

                                  Laura

                                  the modern world does not, you're right and that's a good thing 🙂
                                  but a chastity belt is conservative 😉

                                    Angelina an intense feeling when i hear the clicking of the locks

                                    It is so strong that stop a bit my heart.

                                        Ines

                                        i feel the same way, even though our feelings for the cb are very different 😉

                                          Laura If its a cheap loke I would rake that thing.
                                          If not is not, I atleast require a Bobbypin and a Screwdriver.
                                          Really depends on alot of things.
