In many cases the tendency is to leave your terminal users on a table at a restaurant, office, etc.. To have more control over it, is to design an application that serves to prevent any user to touch our phone, and if you do sound an alarm signal. For example, this application could be used to stop loading our terminal in a hostel and so would avoid that any user could touch.
The application allows the user to start recording a PIN code consists of 4 digits. This PIN code is used to set the alarm to the terminal. If the user has not indicated that PIN and try to turn the alarm on the phone, the application would force him to enter it before you can activate it. Another functionality that will allow the application to change the PIN code. This code will be stored in the terminal and will need to be entered only once, the rest of the time the user may activate the alarm without entering your PIN.
Once created, the user PIN code may activate the alarm from the terminal, the system posts a time frame during which the terminal warn the user that the alarm is activated (to let him on the stand you want). After this interval of time the alarm was activated at the time that there is a change in position, will activate a sound that could not stop unless the user tries to turn the alarm off. To turn off the alarm the user will have to enter the PIN code of the application.
When the system detects that a user is taking the terminal began to read the coordinates as it moves across and anger stored in the terminal. Since the application is you can access these coordinates and display them on a map in Google Maps.
