Passengers at Boston's Logan International Airport were surfing their phones and drinking coffee, waiting to board a flight to Aruba recently when a JetBlue agent came on the loudspeaker, announcing: "Today, we do have a unique way of boarding."
On flights to the Caribbean island, JetBlue is experimenting with facial recognition software that acts as a boarding pass. The airline says it's about convenience. For the federal government, it's also about national security. But for privacy activists, it's an intrusive form of surveillance.
