-A simple payment system
------------------------
-
-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.
-
-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).
-
-Client side security
---------------------
-
-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.
