Bitcoin payments

Bitcoin can be accepted as payment using various techniques. Bitcoin is not recognized as a legal currency in many jurisdictions, but it is increasingly being accepted as a payment method by many online merchants and e-commerce websites. There are a number of ways in which buyers can pay a business that accepts Bitcoin. For example, on an online shop, Bitcoin merchant solutions can be used, whereas in traditional, physical shops, Point of Sale (POS) terminals and other specialized hardware can be used. Customers can simply scan the QR barcode with the seller's payment URI in it and pay using their mobile devices. Bitcoin URIs allow users to make payments by simply clicking on links or scanning QR codes. A Uniform Resource Identifier (URI) is basically a string that represents the transaction information. It is defined in BIP21. The QR code can be displayed near the point of the sale terminal. Nearly all Bitcoin wallets support this feature.
