Merchants must disclose the following on transaction receipts:

• The length of any trial period, introductory offer, or promotional period, including clear disclosure that the cardholder will be charged unless the cardholder takes steps to cancel any subsequent transactions.
• The transaction amount and date for the initial transaction (even if no amount is due) and for subsequent recurring transactions.
• A link, or other simple mechanism, to enable the cardholder to easily cancel any subsequent transactions online.
