Implementation of bitcoin as a payment system

When it comes to payment possibilities on internet, we usually think of payments with credit cards, or paying through online banking. However in recent years because of the raise of cryptocurrencies, alternative payment methods are available such as paying with mobile phone, paying with cryptocurrency or combination of both. With rise of usage of cryptocurrencies, end users and online merchant can choose among alternative payment methods not only as payment method, but also as a store of money and assets. In this work we implement our own solution for payments with bitcoin, which does not require outside service.
