Authentication system e.g. address decoding and access data synchronous authentication system has confirmation device that sends positive feedback with correct authentication data to registration device providing auxiliary functions

摘要

The authentication system has a contactless code (100) that incorporates authentication data having the target address (110) of a performance. Two decoder units decode the target address and authentication information contained in the contactless code. The registration device sends the authentication data to a server of a service tenderer and provides auxiliary functions on the mobile apparatus based on the feedback of service tenderer. A registration confirmation device sends a positive feedback with correct authentication data to the registration device.
