You can book a fully refundable ticket, SSCI, print the boarding card, then cancel the whole lot.
You can also, with a traditional card (not scanned), go through security, shop in the duty free, turn round and walk back out through immigration/customs, give your shopping to your friend, then go back in again. It's been like this for decades and no SECURITY threat whatsoever.
the 'traditional' boarding card is swiped into the system at most airports I use - I guess the same info that is held in the barcode on self printed boarding passes is held in the magnetic strip on the reverse of the airline issued cards?
