What is an Edy card? ~ munejyuka diary

I'm not good at high-tech stuff、munejyuka。
before this、I learned about the existence of something called Edy card by chance.。
deposit cash onto the card、That's something I can't use.。

メリットはなんやろ？
お金を持ち歩かなくても買い物が出来るのよね。Especially since it seems to be available at most convenience stores.、When you go out for a little while, isn't it okay to bring your cell phone and credit card with you? I think we should talk about that.。
I also use this in various places.、Earn points! The story is。

The world has become more convenient.。Is there no one talking about this anymore? how well recognized、I wonder how many people are using it? I haven't seen many people paying at convenience stores, but I guess people who do use it do it.。
