They allow the payment initiation service provider to give the beneficiary a guarantee that the payment has been initiated. These services offer a solution to both merchants and consumers, and also allow consumers to make online purchases even if they do not have a credit or debit card.

The confirmation given does not imply that the payment service provider blocks the funds in the account of the ordering party.
