Fiscalization was introduced in Belgium during several phases, and it is considered to be a combined type of fiscalization, having both hardware and software requirements for fiscal devices. During 2015 and even earlier, the HoReCa sector in Belgium was subject to several regulations regarding the use of cash registers that allow the control of fiscal activities. These regulations were initially planned to take effect on January 1, 2014, but they were postponed for one year to give more time for that sector to adapt. For the year 2014, the use of the cash register system was voluntary.
