Re: How hard can it be?
That was part of the reason I asked the question - didn't know passport numbers changed with any frequency.
My reference to lookup is that in purest objective terms the system needs to lookup an individual (based on whatever information is presented - passport number, fingerprint, eye scan, visa, etc) and then return a result or cluster of information saying 'fine', or 'very not fine'.
To my simple IT sales mind, that in itself is a relatively simple system and process to create - but I can see getting that information from external agencies into the system would be hugely complicated, assuming you'd want them on a live or near live connection to the external data.
