Vouchers
Vouchers are used to fill the balance of a user. You can sell vouchers printed on paper, or sell them over the Internet. When a user logs in and enters a voucher number, his balance will increase by the value issued for this voucher.
All voucher configuration options are in the Vouchers section of the Configuration window.
