If you're tired of being scammed at ATMs by kind, gentle-hearted con artists (and then forgetting it ever happened), you'll be stoked to know that Japan is looking out for you. Chiba Bank has installed phone signal jammers at four unnamed ATMs at bank branches in the Tokyo region, and while it has gone down as the first institution to go to such lengths, we highly doubt it'll be the last. It's not entirely clear what exactly the criminals were able to convince people to do via mobile, but it's probably something like "psst... get me out some cheddar and meet around back." Not that we have any experience in the field or anything...
