A new device that fits on a cellphone could soon replace X-ray machines in airports and security checkpoints, while being affordable enough for schools and nightclubs.

Rather than using X-rays, which often require heavy equipment, the new device, SWORD, uses radio frequency. The technology can achieve effects similar to X-rays, but in a noninvasive way, and with no more radiation than what a cellphone already emits.
