While disclosures are typically allowed to be one click away, I see little validity in the argument that "Member FDIC" is too difficult to present. An alternative would be "Click here for bank disclosures" and that is not very specific. What disclosures is the person supposed to look for, one or more, FDIC, credit card disclosures, ARM plans, etc.? The link should be somewhat specific as to what the person is seeking.
I would instead encourage the bank when the shortest compliant method in its advertising and the "Member FDIC" is short and is required.
