Details

Currently, ACH Originators of WEB debit entries are required to use a “commercially reasonable fraudulent transaction detection system” to screen WEB debits for fraud. This existing screening requirement will be supplemented to make it explicit that “account validation” is part of a “commercially reasonable fraudulent transaction detection system.” The supplemental requirement applies to the first use of an account number, or changes to the account number.
