>How would this data be held and who would see it or have access to it?
Same way as its currently held - by the various governments with (limited) agreements in place to to check each other's databases. Its not that big a leap to have a unified system in place I think. Or at least starting with the 1st world countries.
Not a fan of big government, but this is an area where I think streamlining things would help.
>European countries already issue biometric passports that require you to provide your fingerprints
Yeah got one of those. The fingerprints aren't actively used at borders though - just facial recognition.
