MasterCard Europe presented a set of new rules for the pre-authorized transactions that will take effect in November 2013 in Europe. New rules of MasterCard aimed at increasing transparency and ease of committing pre-approved payment transactions for both consumers and traders. They seek to ensure that:
cardholders must always be informed of the amount that will be authorized for charging
blocking any user’s account or credit line is always carried out within 24 hours of completion of the transaction
the amount which is blocked in the account should not exceed the pre-authorized amount.
