This is a traffic exchange. Basically, you get credits for visiting other member sites and they get credits for visiting your site. It can work, but their are other more productive traffic generation methods available.
It will not have a problem from most seo aspect I could think of. However, the quality of traffics are under the par and you cannot use this type of traffics with Google Adsense or your account would be banned.
Check the referrer pages of those visits. If they are coming from any PTC sites, I'd not recommend using it.
