I would like to buy 2 adult and 2 under 11 cards for use on the subway and buses in Busan.
I hear there are different types and I can just get it at any familymart? I also read online that i need some kind of foreigner id to sign up the kids to get the discounted cards? We are here for 2 weeks and want to make it easy and as cheap as possible to get around. I use google maps directions a lot to check what buses go where and it has been great.
Any suggestions would be greatly appreciated.
