I am thinking about purchasing a bag with an RFID tag in it for overseas travel. Would this create a problem for me when flying?
No, this would not create a problem for you. The x-ray machines would see the antenna as a piece of metal, and security might question you about it, but the transponder should not have any impact on the performance of security equipment. X-ray machines use a far different area of the electromagnetic spectrum than RFID does. Full-body scanners do utilize radio waves, but you are not allowed to take any bags into the full-body scanner with you anyway, so that also wouldn't present a problem.
