Five 400 Word Definitions of Credit Card Terms

I'm looking for someone to write 400 word definitions for each of the five terms below. I have about 25 definitions I want long term but this batch is for the first 5. Basically for each of these I'm just looking for you to start off by defining what they are, then go into more detail by explaining different types, pros and cons, or any additional info you should know about each one. Kind of Wikipedia style. Each 'definition' should be about 400 words in length. Also please keep the definition for each to just their meaning related to credit cards (not other loans). The terms are: Annual Fee Balance Transfer Cash Advance Cash Back (Rewards Program) Credit Bureau ## Deliverables Five 400 word definitions for the following terms: Annual Fee Balance Transfer Cash Advance Cash Back (Rewards Program) Credit Bureau ## Platform N/A - Notepad, Word, whatever.
