Administration of the Tag via the Web DB and Command 0xFF

['Neal Singh]

In loading the Tagging structure, it might be best to use the 0xFF Command as each Tag can be individually added as this sort of this is  a regular occurrence.

The map will be maintain by the WEB DB and it will manage the use of the structure for each of the Tags.

Memory Map Concept
Description	Starting @	Ending  @	#ofBytes	QTY
Setup Config Data	0x000000	0x0003E8	1000	1000 characters

This is the most important table in managing the Tags as this is where the Tag is identified and the direction on what to do with it indexes from here 

Tag Structure (sample)
Tag CRC (1 byte)	Tag # (6Bytes)	TagType (1 Byte)	Status (1Byte)	MemoryIndex(3Bytes)	Total Bytes

All this tables below are best managed by have a replication on the Web DB

The Vehicle Structure should 38 Bytes and it needs to have a Tank Capacity and HBF (Hour between Fills) with Allocation per Period and Money & Liter limits.

If the Vehicle is allowed 200 liters per week and it has a Tank Capacity of 50 Liters, then for the last 7 days, it will check in the Transaction log, how many liters has the vehicle acquired and if there is still liters available, then it will allow fueling but not more than Tank capacity per fill (Actually this is controlled by the  Fuelling Rights
