Utah RFID Toll Payment System

Utah Department of Transportation will implement TransCore RFID-enabled payment system on its Interstate 15 Express Lanes by the fall of 2010, replacing a legacy decal system. The RFID system will support dynamic pricing driven by highway traffic conditions. ...

... "The new electronic payment system will enable UDOT to dynamically adjust the pricing based on traffic conditions. Motorists pay only for their actual usage of the lane instead of the fixed fee for a monthly decal. This system will help UDOT to further reduce congestion and travel times in all lanes. The dynamic pricing system is built around a traffic-condition algorithm. Software collects traffic flow data from the Express and general-purpose lanes to calculate a price that optimally matches demand. The algorithm will use data provided by UDOT’s TransSuite traffic management system, supplied by TransCore under a previous contract. " ...

Alien Technology RFID Tag Signature Authentication Addresses Cloning

Alien Technology has implemented dynamic authentication as a feature on its Higgs-3 RFID chip, enabling data security to confront cloning. ...

... "Dynamic Authentication further enhances security of the Higgs-3 IC by incorporating a challenge/response algorithm which defeats static cloning attempts of the Higgs-3 IC. This innovative custom feature is a verification process comprising a dynamic interaction between the reader and the tag, and is a function of several parametric tag characteristics whereby the tag’s signature is challenged by the reader for Higgs-3 authenticity and confirmed by the host to provide customers with a cost effective, secure identification measure. " ...
