Like bank transfer, debiting is a way to transfer your money from an account to another one.
It allows you to automatically pay your regular bills (Télécom, STEG, SONEDE ...) and avoid forgetting them or making any mistake.
You should fill a debit authorization from beneficiary organization in order to set up the debiting order. The latter will transit draw-down notice to you.
Your account will be debited from the amount of the bill at the deadline.
The debiting can be rescinded at any time through a simple letter.
