Absolutely, just assume that if you buy a ticket directly over any Asian airline's website and use a credit card, that you will be asked to bring and show that exact credit card at check-in. TG does this, and OZ also. Usually, most airline websites will have a pop-up or some sort of terms of sale that explicitly state this.
Note that if you purchased with credit card through a travel agent, the requirement to show the credit card to the airline at check-in doesn't apply, as the airline will be transacting through the agent, with the TA shouldering the risk of cc fraud.
