With its built-in power bank, distance alarm, global GPS tracking, worldwide WiFi hotspot, & on-board anti-theft camera, the Volterman really is the world’s most powerful smart wallet. It’s also lightweight & thin, making it perfect for travel. No more international roaming charges. Thanks! Also, it works wirelessly or with a cable, your call. If you leave your wallet somewhere, it calls to notify you. Thanks, again! A ridiculously over-funded Indiegogo.
