I have developed solutions for branch to branch transactions. A Bank can lodge transaction request which the responding branch authorises or denies. Head Office keeps on getting realtime pending, approved, denied transactions status between their various branches.

Can banks directly start to use such solution or do they have to go through any federal/government permissions to use this facility ?

Most banks already have "any branch banking". Not sure what your product will do that our core system won't. However, if you think you have a product that may be beneficial contact your state's banking association or the ABA.

Thanks, Dan.

One more thing based on your reply : In your terms, what is ' Core Banking ' ? Every banking software tries to explain it differently and there are conflicting views.

What we (I) consider our "core system" is the main processing software which relates all transactions through our server system. (BTW, I'm no techy - so don't ask me how our server system is set up because I can't tell you. )
