Israel’s Lisa Dolev of Qylur Intelligent Systems, is the inventor of the Qylatron – a security scanner with multiple sensors that was used at the Rio Olympics. Visitors scan their ticket and put their bag into one of five cubbyholes. If the bag is safe, they collect it at the other side of the barrier.
