evidence: Electronic voting machines can handle only 16 candidate choices per machine. What happens if there are more than 16 candidates in a constituency. Like 185 candidates for instance, in Nizamabad constituency in Telengana. [...] It turns out, the technology has been made scalable! If there are more than 16 candidates, four EVMs (or balloting units as they are called) can be connected in series to a single master controller to handle 64 candidates. [...] However, in 2013, newer model EVMs were introduced (M3 EVMs) which can handle up to 384 candidates in a single polling station, by connecting 24 balloting units in series to a single master control unit. And this includes the option for NOTA (none of the above) on the machine, in case one does not want to select any candidate from the list.
