I don't know if this is the correct place to ask this and along with that I'm probably just being very paranoid but I'm currently living in South Korea and will be heading home for the holidays to the US. I have bought a bunch of r4 cards for christmas presents will I have any troubles bringing those through airport security in my carry on bag? If so would it be better to put them in my checked luggage? Thanks so much in advance. And you all have a wonderful holiday.
