what Richard said: what is good enough for (German) banks to e.g. open an account, should be sufficient for the NCC as well, me thinks.
in other words, what is good enough for transistrian/lebanese/BVI/iranian/somalian banks - should be good enough for the NCC? what data quality we are trying to achive?
I have to agree with Sergey. I have been through the hassle of getting married to a non-german. For a proof of authenticity of international documents they created the Apostille-agreement in the 1960s. It is enough for the Germans to accept e.g. a birth certificate from Mexico as valid. I could also e.g. request a registration confirmation (that shows my name, dob and home address) from the local authorities and then ask for an apostille to be glued on the document. It then shows that the document is legal and valid. But then, it is required to send by postal mail. And on top of that: not all countries joined the Apostille agreement and trust it mutually. Just because some German companies/banks have trust in PostIdent it does not mean the RIPE NCC should trust in all types of local stuff. Cheers! Sascha
