<p>An additional integrated circuit device can be used for communication with a police station signal receiver and/or a computerised transmission signal exchange. The additional device serves for identifying a person, using a fingerprint testing system. Thus the endangered person can follow computer program system by presing certain keys on the additional device. The computer recognises the characteristics replies after the receiver has been triggered. The system is also capable to be used for opening safety locks on doors, when appropriate connection has been made to the computer program system. After the alarm has been triggered a special test program is associated with the additional device, the test program being answered by specific code operation, taking a very short time. Some of the keys may be operated by signal transmission.</p> |
