Merchants store card details in one of two ways.
- Stored card information means a merchant, such as an online retailer, has saved your card information to make future purchases easier. These transactions require your authorization each time you make a purchase with that merchant.
- A recurring charge is one that a merchant charges you on an ongoing basis. Merchants and service providers may charge a fixed amount each time, or the amount may vary. This is a common practice for subscription services, like phone service providers.
