This application reminds you the code that you need to give at some location (for example, the pin code to open a gate, for accessing a parking).
This application is particularly useful when the code is regularly changed by someone else.
Our backend knows the various locations and their administrators.
At the very first usage, you need to enter your phone number and a PIN code (sent by SMS) to check that you are indeed a known user for accessing the information.
If you are an administrator, you can update this information… a new code by just by entering it; a new user, by entering a "+" followed by the new users phone number.
