1. Member States shall ensure that an account servicing payment service provider shall, upon the request of a payment service provider issuing card-based payment instruments, immediately confirm whether an amount necessary for the execution of a card-based payment transaction is available on the payment account of the payer, provided that all of the following conditions are met:
(b) the payer has given explicit consent to the account servicing payment service provider to respond to requests from a specific payment service provider to confirm that the amount corresponding to a certain card-based payment transaction is available on the payer’s payment account;
(c) the payment service provider authenticates itself towards the account servicing payment service provider before each confirmation request, and securely communicates with the account servicing payment service provider in accordance with point (d) of Article 98(1).
3. In accordance with Directive 95/46/EC, the confirmation referred to in paragraph 1 shall consist only in a simple ‘yes’ or ‘no’ answer and not in a statement of the account balance. That answer shall not be stored or used for purposes other than for the execution of the card-based payment transaction.
6. This Article does not apply to payment transactions initiated through card-based payment instruments on which electronic money as defined in point (2) of Article 2 of Directive 2009/110/EC is stored.
