(11)Exemptions for low-value contactless payments at points of sale, which also take into account a maximum number of consecutive transactions or a certain fixed maximum value of consecutive transactions without applying strong customer authentication, allow for the development of user-friendly and low-risk payment services and should therefore be provided for. It is also appropriate to establish an exemption for the case of electronic payment transactions initiated at unattended terminals where the use of strong customer authentication may not always be easy to apply due to operational reasons (e.g. to avoid queues and potential accidents at toll gates or for other safety or security risks).
