As I have said, from July 1, Belarus introduces new notes and coins into circulation. This reminder will help you cope with the difficulties of translation of old banknotes with new ones. I recall that until January 1, 2017, all banks and shops in the country will take the old bills and new.
Special application for phones have been developed in Belarus. If you are going to visit my country during the transitional period (from 1 July 2016 to 31 December 2016), I recommend you install this application to simplify the work with new and old bills.
