TRANSPORTATION VEHICLE USER RADIO FREQUENCY IDENTIFICATION SYSTEM Russian patent published in 2004 - IPC

FIELD: radio frequency identification technique.

SUBSTANCE: proposed system has one or several tags are coupled with reader by the air. Reader has transmitting-receiving radio unit provided with aerial, signal processing unit and micro control unit. All units of the system are connected in series and correlated among each other. Light or audible signaling units are connected to outputs of reader. Tags and readers are made to proceed dynamic identification dialog when tags are located at the area of reader's operation. During dialog between tags and reader the signals with random numbers are periodically transmitted to reader to tags. Then random numbers are subject to non-linear transformation in reader and tags and non-linearly transformed random numbers signals are transmitted from tags to readers and transformed random numbers are subject to comparison with numbers presenting in reader. Tags and reader have the same are made to have the same design which provides their interchangeability. If reader is disposed at user's vicinity the system has signaling which shows how far the user locates from his/her personal stuff and works as personal guard.

EFFECT: improved functional capabilities.
