Can Smartphones Replace House Keys?- My Reaction

        "Can Smart phones Replace House Keys?" the article which was published in The Week magazine, on July 6, 2011, highlighted a new contemporary technique that allows people to use smart phones instead of regulars keys. The usage of this unusual technique  is focusing on the opportunity to lock the outside door from any distance. Specifically, by sending the vibrations from the users own cell phone to the installer device on the door. Moreover, this technique is contributed  many advantages. One of them is the achievement to develop a new mouthed for people safety. For example, the specialist engineering who are responsible about creating this technique  in order to grape people attention to their positions. However, it may have an unprofessional  side in the way long of using the advice. Another advantage is that the owner of the positions is the only one who has the power of controlling the advice by entering  a secret code of number to his/ her cell phone. Despite there is a disadvantage for the previous advantage . Controlling the advice by one person, will make it is extremely hard  for anyone else to control the advice. One of the circumstances that it could happen when the device is suddenly locked. For instance, If the owner is outside of country, he may get the help that he want by calling friend who have the advice secret pass. But how a friend could help if the only media which is controlling the device is the owner cell phone. After display the advantage and the disadvantage of switching the regular key with the  new a device. In my prospective, I tend to accept this new technique after it guaranteed qualification of its work. And I assume this new technique will prove the ability after the third generation. In brief, I believe that either way will give the purpose of using it.
