processing credit card payments through a Blogger website

It would be nice if one could process credit card payments through a Blogger / Blogspot website. Is this possible, is it allowed, and how could this be implemented?

well you can process credit card payment through blogger site by using paypal.you will have to signup to paypal and get a account there paypal is the most secure and affordable payment gateway.signup is free and there is no annual charge but you will be charged for each transaction.and to integrate paypal button to your site you will find instruction on paypal website there you can find out how to generate javascript code which you can add to your blogger blog just like any other html code.i hope this helps.

PayPal is an option as someone else suggested, however I preferred to use a merchant service provider when i began to accept credit cards (it was an easier and less stressful way to let them handle it) This is the site I used and the company I signed up with.
