You will get written up on this as a violation of Reg E if you don't mention in your EFT disclosure that Online Banking is an EFT service and describe what actions you can do ie Make transfer, initiate payments, etc. Also, in your online banking contract, make sure you don't tell your customer that you accept no liability for errors or problems. Reg E governs online banking transactions.
These are my opinions and not those of my employer.
