payment options

Hi I am new to Booking.com,

As far as I understand it my settings are set so that payment can be paid online or directly to myself on departure.

When I look at the booking confirmation I don't find it very clear.

It either doesnt seem to state anything or states paid online.. (so I guess if it doesnt state paid online they need to pay for it directly).. but I dont want to presume.. I'd rather know for sure than ask for payment if I shouldnt be.

Also, some say 'virtual credit card' ??? as payment

Is this payment taken directly via booking.com or do I need to take it directly ?

Hope this makes sense, thanks in advance
