Make sure your email is verified, and you have selected our Free Membership plan. You can check this on your account settings page. The additional scans will be deposited monthly on the day of the month you joined. For example, if you joined on May 20th, you would receive the additional scans on June 20th, July 20th, and so on. Your free scans will be added each month until you hit a cap of 5 unused scans. Use your scans each month to get additional scans.
