Tired of ripping off those old luggage tags after a trip? Well, those could be a thing of the past if all goes according to plan -- at least when flying British Airways. The airline cooked up an electronic bag tag that looks to discard the paper version with the help of the folks at Designworks. Once passengers have checked in, they simply need to hover a smartphone over the tag to beam (via NFC, we'd surmise) both flight info and the requisite barcode to the tag's display. The idea behind the whole thing isn't only to keep the paper-changing to a minimum, but to also save precious time at the check-in counter. A live trial of the tagging gadget is planned, so we'll soon be able to see if the concept stands up to baggage handlers.
