Bitcoin for Developers
Bitcoin can be used to build amazing things and provide solutions to common problems.
The simplest of all payment systems
Unless a payment needs to be associated with automatic invoices, accepting money is as simple as sending some bitcoin - just display an address or QR code. This simple setup is within reach of almost all users and can fulfill the needs of many clients. From an accounting perspective, it's especially suitable for reducing overhead and adding transparency.
Many third party APIs
There are many third party payment processing services that provide APIs; you don't need to store bitcoins on your server and handle the security that this implies. Additionally, most of these APIs allow you to process invoices and exchange your bitcoins into your local currency at competitive costs.
You can be your own bank
If you don't use any third party APIs, you can integrate a Bitcoin node directly into your applications allowing you to become your own bank and payment processor. With all the responsibilities that this implies, you can build amazing systems that process Bitcoin transactions however you would like.
Bitcoin addresses to track invoices
Bitcoin creates a unique address for each transaction. If you were to build a payment system associated with an invoice, all you would need to do is generate and monitor a Bitcoin address for each payment (you should never use the same address for more than one transaction).
Most of the security is on the client side
Most security is handled by the protocol, eliminating the need for PCI compliance. Fraud prevention can be simplified down to monitoring a single variable: the confirmation score. Beyond that, keeping your bitcoins secure is mainly a matter of securing your wallet and using HTTPS or other secure protocols to send payment requests to customers.
A new world of possibilities
Bitcoin allows you to design new and creative online services that couldn't exist before due to financial limitations. This includes tipping systems, automated payment solutions, distributed crowdfunding services, time locked payment management, public asset tracking, low-trust escrow services, micropayment channels and more.
