Credit Card: There are two main no deposit credit card categories:
An unsecured credit card which allows typical purchases from retail stores, booking airline and motel reservations, etc. Examples of this type of no deposit credit card include Visa, MasterCard, Discover, etc.
The second type is not an actual "credit" card. It is a catalog card. It's an unsecured card (catalog, merchandise or discount card), which can only be used to purchase from a select line of products or from a catalog endorsed by the card issuer. Examples of this type of no deposit card include a Sears credit card (charge card).
A no deposit credit card is an unsecured card that does not require pre-paying in order to enjoy a line of credit. These types of cards are more widely known by major issuers such American Express, Chase, Discover, MasterCard and Visa. Some issuers also offer a no annual fee credit card.
There are some cards by these major credit card company issuer which have a deposit or "pre-pay" requirement. The ones that are no deposit are aptly named "credit cards" and those that require a deposit are referred to as "cards" (without the word "credit"). Why? Because "cards" that require you to pre-pay are secure cards, and the amount you can charge against the card is determined by the amount of your deposit. If you deposit, for example, $1000, then you can charge up to $1000. Hence, there is no actual "credit" being extended. Typically, these cards are marketed as no credit credit cards because of the easy, no credit check approval.
