According to a press release dated 31 July 2018, the Bank of Zambia plans to upgrade the security features of its banknotes. Specifically, the 20-, 50-, and 100-kwacha notes will have a SPARK Live feature added at lower right front and a 5-mm wide windowed security thread. The 10-kwacha note has a new windowed security thread, and the 2- and 5-kwacha notes have different images in glossy varnish with blind embossing. All denominations have tactile marks for the visually impaired. The two smallest denominations are expected to be introduced in August 2018, with the remaining denominations issued in a phased manner, and existing notes continuing to circulate in parallel.
