Product Description

The iButton is used here as a key to the access control system. Its unique identification (ID) number is used for authorization. On detection of an authorized iButton, the system allows access.Thereafter, an automated lock key locks the system again. The system is permanently halted after five repeated false attempts. A service control unit built around an AVR microcontroller is interfaced to the iButton with the 1-wire protocol for authentication of user validation of data.
