The concise “yes” is correct, but a more explanatory answer might be helpful. Cannabis is still a schedule 1 substance by federal law. Almost all federal jurisdiction in state matters is derived from the interstate commerce clause in the constitution. When the first states passed legalization measures, the DOJ issued a memo (Cole) basically saying they would not intervene in states with well defined rules for tracking cannabis sales to prevent product crossing state lines. Credit card processors and most banks are either not willing or not allowed to process electronic transactions for cannabis because they do tend to cross state lines.
