Log in to your Checkbook.io account.
If you have only received a check and not created an account, use this link to set a password to the checkbook account that was automatically created for you with the email that you received the check on.
Go to "Settings" on the bottom left-hand side of the page.
When in Settings, click on the "Accounts" tab.
When in "Accounts", click "Verify Account".
Verify your account by making micro-deposits that will be be applied to your account by the next business day.
Under "1st credit amount", we recommend adding $0.01
Under "2nd credit amount", we recommend adding $0.02
This would send $0.03 to your bank account through Checkbook.
Under "Total debit amount", add the summation of "1st credit amount" & "2nd credit amount", which in the recommended scenario would be $0.03.
This would take back that $0.03 that was sent to your bank account, thereby verifying your account.
