Can I transfer money between accounts and what is the fee of doing so?

You can transfer money between your accounts via transfer within the DNBC network function, which is under the remittance tab in DNBCnet. This would be the same as you sending money to any contacts within the DNBC network with no occurring fees at all. The time it would take is the standard time for any remittance, which means it would take 2 working days for your money to reach your destination account.
