I have been unsuccessful in finding out who carried this bill in the USA Congress. If anyone knows, please post here.
"Different kinds of copies of a check will have different rights attached. Check 21 creates a new kind of paper copy of an electronic image of a check. This special kind of copy is called a "substitute check." Only a substitute check can be the legal equivalent of the original check, and only a substitute check triggers your right to recredit of disputed funds. A regular copy of a check does not carry these same protections. If you ask for a copy of a check, your bank may send you an ordinary copy instead of this special kind of copy which triggers legal rights and protections unless you ask for a substitute check."
Anybody wanna guess if the banks will charge you for ordering "substitute checks".
