For each payment thereafter, the merchant will have to send a receipt to the cardholder for each transaction by email or text message with clear instructions on how to cancel the service if the consumer so desires. In addition, all charges that appear on the cardholder’s statement must now include the merchant website URL or the phone number of the store where the cardholder made the purchase. This looks like a significant change in policy. I wonder how merchants are supposed to know about it unless they happen to have read a source like HN today and found their way to the original MC article. I also wonder what the consequences will be for non-compliance and what will happen if a situation is misunderstood by a payment service like PayPal or Stripe. For example, if we have a regular subscriber who is changing to a new card, we will typically use the payment service's "trial period" facility to delay the first charge on that new card until their regular renewal date so they don't get double-charged for the period in between. That's not a trial period in the normal sense of the term; to the customer, it just means they carry on paying exactly as they have but payments start coming from their new card instead. But there's not necessarily any way for a payment service to know that.
