VDC is used if you want to bill the clients yourself and then you pay the wholesale cost.
If
you have never used VDC before you may wish to change the VDC pin to
make it more secure. In your admin panel click visp then edit. You will
see the current vdc pin code. Just type in what you wish it to be and
click update.
Then when placing orders click pay by VDC, at the end of the order process you will need to put in your VDC pin.
To use the VDC you will need to have signed up to Direct Debit as this will be used to top up money into your VDC.
