Regarding the Nov. 19 article "Police probe credit card scams involving airborne duty-free": If the problem is the verification of credit card details in flight, why not implement a system where only credit cards that have been used to purchase the flight ticket itself can be used in flight?
Credit cards verified on the ground at the time of purchase should be no problem. Airlines know which credit cards have been used to purchase which seats, and passengers can verify their identity in the case of any confusion due to seat-swapping, moving to other parts of an aircraft, etc. All other credit cards would then be refused.
