5.2.1.3 Annex 5: Road transport and traffic telematics
Annex 5 describes frequency ranges and permitted transmission power for short range
devices in traffic telematics and vehicle identification applications. These applications
include the use of RFID transponders in road toll systems .
5.2.1.4 Annex 9: Inductive applications
Annex 9 describes frequency ranges and permitted transmission power for inductive
radio systems . These include RFID transponders and Electronic Article Surveillance
(EAS) in shops.
