By the end of May 2020, the Czech response to the COVID-19 pandemic has been recognized as a “ success ” following the fast introduction of strict nationwide preventive measures, nicknamed a “ blanket quarantine ” . This article focuses on the alternative and rival concept of a “ smart quarantine ”, which emerged at the beginning of the lockdown . Inspired by Korean and Singaporean anti-COVID-19 smart city solutions, a group of ICT professionals volunteered to develop a system that promised to help limit the spread of the infection and, at the same time, ease the nationwide lockdown within a foreseeable time . The idea was received enthusiastically, yet, two months later, smart solutions are still not fully integrated . This article reconstructs the story of the smart quarantine in Czechia and suggests considering possible societal consequences of unsatisfactorily valid smart tracing methodologies . Rather than seeing lockdown and smart solutions as opposite approaches to the current risk, it shows that a hybrid strategy may be considered, if not necessary, especially in contexts where smart solutions have been previously applied only to a limited extent.
