Hi,

I want to know about eCheck Functionality. Actually I've implemented the eCheck functionality.

Now I need to know is it works for US banks only or it works for all banks in world. 

Or how can I identify that eCheck will work for which bank? (Merchant should have a bank in US or could have outside the US).

And beside this I've some quires 

1) What is Receiving Depository Financial Institution (RDFI)?

2) What is Originating Depository Financial Institution (ODFI)?

-Thanks
