Manufacturer Royal Holdings offered customers a brand new SWORD. Designed for the iPhone 8 Plus and Google Pixel 2 XL, this case is capable of detecting hidden explosives and weapons. The device has 18 antennas. As a sonar, it uses sound waves to identify weapons and explosives at a distance of 12 meters. A special application allows you to determine whether a passerby carries dangerous objects. The scan results are pre-compared with items entered in the built-in database. As the creators of the device, machine learning will continuously improve recognition accuracy and database. The device also knows how to scan faces, comparing them with photographs of certain people. For example, those who were forbidden to appear in a particular protected area. The authors of the product promise to demonstrate a working prototype of the device at the end of summer. And sales should begin in the coming year. The price of the issue is 1250 dollars. Moreover, the gadget needs a monthly subscription worth another $ 30 to work. The cost is high, but the manufacturer managed to accept orders for the production of 8,000 such cases.
