Abstract
Systems and techniques are presented for identifying fare evasion at an access control to a paid area. Received signal strength (RSS) is determined for wireless signals communicated between two or more wireless transceivers and a fare media. A position of the fare media is determined based on the RSS and the position is added to a collection of positions. A position of an object is detected and the position of the object is compared with each position in the collection of positions. A determination is made that the position of the object is not proximate to any position in the collection of positions and an indicator light is generated on the floor proximate to the position of the object.
