The adoption of smart card technology in various parts of Africa has reduced electoral malpractices, resulting in election credibility and acceptability. However, its use in Nigeria’s electoral process is believed to have downsides. The paper investigates how adopting smart card technology reduced electoral malpractices during the 2019 presidential election, making it more transparent, credible, and reliable than the traditional technique. It uncovers the flaws of the technology in Nigeria, including card reader malfunction, delays in accreditation and voting, the inability of the INEC staff to operate the technology efficiently during voting, and election postponement, among others. It is therefore recommended that the INEC improve public awareness of the use of the technology and train its staff.
