In Saudi Arabia, Siri tells you everything your wife is doing. Males will automatically receive text message notifications whenever their spouses, relatives, or daughters pass through travel checkpoints, the International Business Times reports:
Saudi Arabia has introduced an electronic tracking system to monitor its female citizens and alert Saudi females’ male guardians to their movement.
Since last week, some Saudi women’s male guardians have been receiving text messages from immigration authorities, alerting them when women under their [control], which include wives and daughters, leave the country. To leave the kingdom, Saudi women are required to seek permission from their male guardians, who give consent by signing what is known as the “yellow sheet” at the airport or border.
The recent controversy caused by the escape of a Saudi woman to Sweden was believed to have prompted the authorities to implement the system, Al Arabiya reported, citing local media.
