How does CarJam provide free Basic reports?
The short version:
The longer wordy version:
In December 2010 the New Zealand Transport Agency (“NZTA”) began imposing a fee of 16c for queries from CarJam to the Motor Vehicle Register (“MVR”) for Basic vehicle information like WOF, COF, rego and basic vehicle details – previously these queries had been free allowing CarJam to provide unlimited free basic reports to the public.
To provide the maximum amount of free data to the public despite these government charges CarJam puts all the queries we do into a cache of data which we can provide at no cost. Its like recycling old reports.
We provide 3 free basic reports per month to registered users of CarJam and these free basic reports can be used to look up any plate which is not currently in the cache of previous queries.
Of course some of the data in these cached reports like WOF, rego, license gets stale and needs to be refreshed. Refreshing these stale reports requires a registered user to purchase a full report – we use the money paid for these reports to fund the hundreds of thousands of free reports we provide to users – those “free” reports actually cost 16c as mentioned above.
Alternatively you can add a plate as a “favourite” from My CarJam and it will be maintained using overnight lookups which are much cheaper.
