Rape is the fourth most common crime against women in India. Married women, living alone, face a greater risk of being attacked when they go to collect remittances from their husbands who work abroad. In an effort to protect these women—and thereby further its business—Vodafone will send "self-defense umbrellas" to recipients of money sent with their M-Pesa mobile money transfer service.
There isn't a hidden sword or taser, unfortunately. Instead it comes with pictorial references of self-defense techniques and how they can be used to fight off an attacker.
