When you visit a web page, you can pay for the content by clicking Yes in a dialog box. When you don't have money in you wallet, you can fill it up using your credit card, or some bank solution. The price is shown in your currency of choice, but all the transactions happens on the blockchain.
People who make web pages can paste in some javascript to charge for content. No third party organization needs to get involved and the seller can't get charge backs. The transaction fee will be low so that you can charge pennies for a news article. This will work without you giving away you credit card number, name, address, e-mail etc. to the seller.
