All banks use software that does the same thing but their user interfaces are all different.
For specific help, please contact your bank.
Interface File Formats:
All trading banks will accept the file named filename.txt except the BNZ
BNZ Warning:
Before importing an interface file to the BNZ software you need to change the extension to .afi
For Example:
Save the interface file from the Club Manager software as memberdd.txt
File the interface file and rename as memberdd.afi
