IRC:SP:73-2015 152 3.2.2 In the first case, the tag initiation software shall generate a random initiation code, write in the tag and store in the central database as mentioned in 4.1.2. Each time a tag is read by the transceiver for tag commissioning, a new initiation code will be generated, written on the Tag and stored in the central database along with other information. 3.2.3 In the second case, the tag initiation software shall generate a random initiation code and read tag ID, EPC code, vehicle registration number & vehicle class code from the tag mounted on the windshield. After due verification from the central database, the value of initiation code shall be updated on the tag as well as on the central database. Old initiation code and EPC code shall be marked for special handling for 'catching' the clone as and when the cloned tag comes into contact with transceivers at the toll gates. 4 Automatic Vehicle Identification at Toll Point 4.1 The communication sequence between the transceiver and tag shall conform to ISO1 8000-6C. 4.2 The transceiver shall retrieve the tag and EPC memory contents for those tags whose EPC code satisfies the mask stored in the transceiver for a matching entry. The EPC code shall be used to index in to the data base from where the tag 10, vehicle registration number, the vehicle class code and the initiation code will be retrieved from the data base and verified against the corresponding values read from the tag. 5 DATA FORMAT 5.1 Schematic

The toll tariff can be based on vehicle class, lane type, time of day and shall be applicable from a given start date only. The table will contain all the toll tariff records- the old, current and future. Any discounting for local road users must be done by the clearing house. The table is likely to be
