[TYPO3-commerce] Payment methods credit card and prepayment iwith commerce

[Markus Kobligk]

Hi group,

I'm planning a shop with Typo3 and would like to use the Commerce 
extension for this.

Is the integration of the above mentioned payment methods possible with 
the Commerce extension? Especially I'd like to know how the payment via 
credit card works. Do I need to register at a third party company who 
handles the payments or how does this generally work?
Has anyone experience with this issue in combination with the 
Commerceand extension and can give me tips or recommendations which 
third party to use for credit card payments and how this is implemented 
in Commerce?

How is the payment method "Prepayment" handled in Commerce?

I would be happy about any hints, comments, links and recommendations.

Kind regards,
Markus
