AffiBank controls the visitors sent by affiliates using two methods combined:

1. Via cookies: Cookies are installed in the visitor's browser and are kept there for 90 days after their first visit.
2. Via IP address: Visitor's IP addresses are kept on record and linked to the affiliate account that has sent them in. This record is also kept for 90 days.

This means that if you send customers using your affiliate link, your commissions are guaranteed even if your customers purchase 30, 45 or 89 days after their first visit and even if they happen to clear cookies on their browser.
