Podgorica (MINA-BUSINESS) - The authorised maintenance service for Sharp cash-registers in Montenegro Sekas has completed a delivery of all cash-registers, complying with regulations of the Public Revenue office, director of Sekas Djordje Markovic told Mina-business. Buyers could use four-month loans to pay for the cash-registers, he said. The Sharp cash-registers have so far been installed in around 7,500 or 90 percent of all Montenegrin enterprises. Kiosks selling tobacco and daily newspapers are exempt from the obligation to have a cash-register but very soon, the cash-registers would have to be installed in kiosks selling a greater variety of goods. Demand for cash-registers of Omron and Optima brands has been lower and the Public Revenue Office has registered only 200 machines of the two producers installed.
