Free photocopies on Advertising-sided paper....

Why there's only Japanese...I couldn't understand anything.....How can I evaluate the idea..Ahhh...So I must guess what it said on that website.....
Tadacopy in Japan offers students free photocopyying though there is no reason why the business model could not work more broadly.The revenue comes from advertising placed on the reverse side of the paper....

So maybe they gained profit from students and specially university students that need a lot of photocopies.And the main point in this business is even they do photocopies free for students.But on the other side,they advertise their company brand or maybe they have profit from the other companies that want to be advertised.And then,they have ben paid.This is a really creative kind of business and I think many companies want to advertise their organisations by that way too.Be cause everybody knows that students are very active.They are travelling,Shopping,And goes every where.So maybe,students are the best way to advertise company's brand.This is a good idea,and I like that.We can make profit from the other companies that pay for us...and the thing is just......We need a lot pieces of paper.....(^_^)
