It’s that time of year again. Prepare for inspection. Get to the airport hours early, just to stand in line with other sleep-deprived travelers. March forward, splay open your belongings. Separate your valuable electronics and leak-prone liquids into trays. Try to ignore the frustrated tutting of the guy behind you. This is the airport TSA shuffle we all know and abhor. But now, thanks to new technology, the experience is set to improve.
