The apple watch is so much fun in airports! Except when you fly BA, who use a scanner that you can't actually fit your wrist under! However the rest of the time it makes for a few compelling use cases for the watch concept T3 in Heathrow recently.. Boots (pharmacy) really really pretty Irish store manager working the till I walked up to. Asked to see my boarding card, sure. Swipe, tap, swipe- beep.. Cue her looking at me like I'd just fallen from the sky and saying in her gorgeous voice. Ok, that was cool, what am I missing! Then she told me what I owed and I said "if you think that was cool, wait till you see this.." button button swipe to get to my amex and boom! If I had been 10 years younger and 40lb's lighter, I'd have so had her number! Sadly because of the BA equipment, I had to get my phone out a few times but to get through into security and other boarding card/payment bits it was just so convenient.. One problem I did discover is when you have a vertical scanner that points upward. When you turn the wrist to let the scanner see the barcode, the watch thinks you've put your hand down and turns off the screen.. Apple need to ensure the screen stays on for 10 seconds at least when you select a passbook barcode, regardless of what you do with your wrist.. It makes travelling just a little less stressful, which in my book is worth a fortune! Especially as I've left my wallet behind in a shop at least twice when in an airport..!
