As a counter argument: some countries (like the USA) accept mass mail-in voting, which has the same downsides as online voting (plus the “ballot took five weeks to reach the next town so your vote didn’t count” problem with an underfunded mail service).
Which isn’t to say digital voting is good, but clearly many people value the easier participation over the verifiability/security of normal voting.
Most of them act(ed) like an access point.
However, the SDIO spec allows for cursed applications like WiFi adapters, Bluetooth dongles, and more to be fitted into an SD card. It was really just SPI, so in theory it also allowed things like GPS tranceivers and any other peripheral you can think of that’s low bandwidth enough to work over SPI. Need Bluetooth for your Palm PDA? Here you go! Just stick a massive slab of plastic into the SD card slot!
These days SDIO is only really used for alternative (faster) transfer modes and maybe some slow and insecure WiFi access points in cameras.
