Hi all

I am now working on a project for a financial institution (Bank) and I would like to know
how the bank system identify a specific customer and what accounts that specific
customer holds in the system. What I want to do is similar to the Internet banking system,
when a customer applied for Internet banking service, all its accounts can be managed
in the Internet banking instead of having each account apply for a Internet banking service.


So, how can the system find out the accounts belong to that customer? The bank I am working
with said they use the Identification No. or Passport No. of the account and I would like
to know if most banking systems also use this approach? Please let me know if you have
worked on that field and any other suggestion is very welcome. Thank you!!


Kind Regards


Edmond
