There are many different types of credit cards with different benefits. Each individual card is unique in terms of their specific benefits, but all cards fall into a few general categories.
Standard credit cards, often called vanilla or plain vanilla cards, are the most basic of the types of credit cards, as they do not offer rewards & are pretty straightforward in their terms.
Unsecured cards are what most people think of when they think of credit cards. These cards allow you to spend up to a set limit without putting up any form of collateral.
