Payment Services Directive (PSD2)

(71) In the case of an unauthorised payment transaction, the payment service provider should immediately refund the amount of that transaction to the payer. However, where there is a high suspicion of an unauthorised transaction resulting from fraudulent behaviour by the payment service user and where that suspicion is based on objective grounds which are communicated to the relevant national authority, the payment service provider should be able to conduct, within a reasonable time, an investigation before refunding the payer. In order to protect the payer from any disadvantages, the credit value date of the refund should not be later than the date when the amount has been debited. In order to provide an incentive for the payment service user to notify, without undue delay, the payment service provider of any theft or loss of a payment instrument and thus to reduce the risk of unauthorised payment transactions, the user should be liable only for a very limited amount, unless the payment service user has acted fraudulently or with gross negligence. In that context, an amount of EUR 50 seems to be adequate in order to ensure a harmonised and high-level user protection within the Union. There should be no liability where the payer is not in a position to become aware of the loss, theft or misappropriation of the payment instrument. Moreover, once users have notified a payment service provider that their payment instrument may have been compromised, payment service users should not be required to cover any further losses stemming from unauthorised use of that instrument. This Directive should be without prejudice to payment service providers’ responsibility for technical security of their own products.
