I have never used direct deposit, so I don't have any personal experience to draw on. But here is the information I copied directly from the FAQ's:
"How does Direct Deposit work?
If you wish to receive payment via Direct Deposit, you must furnish your account and routing numbers, as well as consent to deposit.
Once you receive the "Cashout Approved" email, allow up to 7 business days for a credit from "FUSIONCASH/DISBURSEMENTS" to post to your account.
Direct Deposit payments are only available for United States members; Canadian reisdents must use PayPal."
I would say that if you got a message saying your payment was approved, then there is nothing to worry about! Congrats on your pay out!
