You can find ATMs almost everywhere, principally for drawing out money using all major credit or debit cards (e.g. VISA, MasterCard). Certain banks offer the facility to deposit cash or pay bills by ‘virement’, i.e. bank transfer. ATMs are open 24 hours a day.
Cash withdrawals are generally not free of charge, except from your own bank’s cash dispensers. Some banks have special packages for a limited number of free withdrawals in Luxembourg and in the rest of the EU.
