Need comments / feedback on modified version of COD and EU Bank Transfer module

[roystik]

I made a modified version of the COD and EU Bank Transfer module. The main difference between the existing modules is that here, if the seller has 2 bank accounts for different currencies i.e. USD and Euro, and offers these currencies in the shopping cart, then the payment module would detect the customer's currency and display the correct bank info accordingly.

Before I go live with this, I need to know if the modifications I made are 1) safe and secure enough to go live, and 2) if there is any way to make it more streamlined / elegant in terms of the code where it determines the currency?

So if the more advanced PHP programmers in this board can go take a look and offer their comments, feedback and suggestions to a PHP programmer wannabee, it would be much appreciated

Thanks in advance!
