The idea is as follows: "To address this problem, Heathrow Airport has pioneered a new technology through its boarding card system that is designed to track the locations of passengers in the airport as well as direct the passengers where to go or what to do to catch their flight on time. With the new system, which the airport is calling "positive boarding," passengers simply present their boarding cards at an automated gate where the boarding card barcodes are scanned. The gate's computer cross-references information from the barcode with flight details and, once verified, the passengers may enter the departure area. Information about their flights also pop up on a screen, so passengers will know if they are in the right terminal or if they have to go somewhere else."
I didn't really have any strong feelings on the matter, positive or negative. When I carried on reading however, what did jump out at me was the following:
"If a passenger arrives at the gate less than 30 minutes before the plane is set to depart, she will not receive access to the terminal and will need to visit the check-in counter for more information."
Sorry what? she will not receive access to the terminal? Is the suggestion here that the women cause the delays due to their excessive duty free shopping? I'm hoping that a simple / was missed out here (which would make it a far more acceptable s/he).
