Tokyo, Japan

Tokyo banks have started installing jammers at strategic ATM locations around the district so that elderly folks won't fall for phone frauds. This is in response to swindlers who target the elderly, asking them to go to the bank and withdraw cash from ATM machines for a needy child, while remaining on the line, only to mug these elderly people shortly thereafter. The devices are said to be of low power, only covering an area of approximately 2 meters.
