Abstract: An apparatus and method for sharing capsule image data and beverage preparation parameters, from one or more beverage preparation machines with a remote computer system via a network, such as the Internet, is disclosed. The remote computer system may process the capsule image data to determine characteristics of the capsule (e.g., a type of capsule, such as a brand, or beverage ingredients in the capsule), thereby relieving the beverage preparation from having to determine information about the capsule. The remote computer may track a user's consumption of capsules, may compare this value to the user's past capsule purchase history, and may determine if the user's supply of capsules is below a threshold value (e.g., below a week's worth of capsules).
