The BioStar 2 Mobile Card does not require a separate portal service. The administrator can issue a mobile card instantly from the BioStar 2 or BioStar 2 Mobile application, and the user can use the received mobile card immediately, just by registering it in the BioStar 2 Mobile application. In addition, the process of collecting issued cards is simple. The Biostar 2 Mobile Card can even store biometric information, as well as general information and user access rights in smartphones. It is safe, since all information is stored on these phones without storing user information in the access control device. In addition, the information on the smartphone is not stored in BioStar 2 or in the access control device.
