A few of our readers have wondered what benefits an IC Card for Street Fighter 4 offers.

For the record, this is a card you can purchase in Japan, and is only supposed to work on machines networked there. Since SF4 isn't officially released outside of that country, it doesn't work on (any?) machines outside of the land of the rising sun.

But here's the skinny:

• Card saves your win total.
• Using one accrues battle points which you can use to unlock alternative costumes and accessories.
• You can use your cell phone to redeem mobile phone wallpaper and ringtones.
• Cards cost from 300 to 500 Yen — about $3 to 5 dollars in American currency.
