When the website Tumfweko first broke the news last October about the Zambian Central Bank using alternative currency printers other than the traditional supplier De LaRue, it took a long time for the Central Bank to own up to the new arrangement. 
Wavuti ya Tumfweko ilipotangaza habari hizi kwa mara ya kwanza mwezi Oktoba kuhusiana na Benki Kuu ya Zambia kuamua kutumia mashine mbadala za kuchapisha noti mbali na mzabuni aliyezoeleka De LaRue, ilichukua muda mrefu kwa Benki Kuu kukiri kufanya hivyo.
