Bachelor degree thesis 
SUMMARY. This thesis work aims to design and develop an Android application, called Infocard, able to better manage contacts through a "smart" address book with some references to typical social network functions. In particular, through a system of requests, it is possible to view the personal data of users, such as profile picture, nickname, name, surname, especially e-mail and telephone number, and keep them close at hand within Infocard.
BACKGROUND AND REASONS. Taking advantage of it in many respects, it is increasingly common to have / change more telephone numbers and more e-mails. When a change or addition occurs, the user should notify all contacts. For this reason I have developed an application that updates itself automatically.
CONTRIBUTION. Through a system of requests, authorization is requested from other users to view the data. Developed via Android Studio (in Java) and server side with the use of Firebase.
!!! Attention to privacy, the possibility of occupy less phone memory, also reducing the risk of losing information. !!!
FUTURE WORKS:
Ability to click on the number or e-mail and be able to call or send the e-mail directly.
Ability to revoke access to users or to show only a part of the contacts.
Ability to add additional fields to display, such as information on social networks.
