well its about time for a change and aside from this new series of notes downsides they also have many more good sides such as the the new feature for accessibility for the visually impaired and in making the banknotes easier to authenticate, harder to duplicate (alot of security stuff added such as "raised print", a new "feel" to the paper used to make the bank notes and not 1 but 2 water marks, a metallic security thread which changes colour (i.e dark to red to green depending on how the bank note is held)and 1 golden stripe at the back printed with a special iredescent ink so that if you move the note around in the light you can see a repeating pattern of the note value in both arabic and english and ofcourse a hologram (only in the 5,10,20 bd banknotes)).
anyway here are a few news links ....sorry cant find the pictures of the new banknotes online so took a few not so "good" ones from the brochure i have
