Anyone here in Japan and use an osaifu-keitai? I have a question about the IC card.... I am currently using Suica with my phone and was wondering if I can also use Nanaco (7-11) at the same time? Can I buy something at 7-11 using Nanaco and then go jump on a train using Suica? I've searched the internet the best I can and I asked a 7-11 employee and both got me no where. Any help is appreciated.
