The Bachelor thesis focuses on acces systems including administration of locks, groups of users, users and their identities. For simple implementation of the system have been created four significant elements of the project: a web interface Locker, an application server Authentizer, MySQL database and an Android application. The web interface is used for system administration and included communication with the database. The server application is used for a communitation between the Locks and the MySQL database. The pivotal role of the server application is verification identities of users. The sever application and the database are used as publishing API. Android application is used as identity instead of identity card
