FIELD: information technology.
SUBSTANCE: invention relates to an optically readable code support to be associated with or be part of a capsule indented for delivering a beverage in a beverage preparation device, support comprising at least one sequence of binary symbols, represented on support so each symbol is sequentially readable by a reading arrangement of an external reading device, while capsule is driven in rotation along an axis of rotation, wherein binary symbols are essentially formed of light reflective surfaces and light absorbing surfaces. Code support preferably comprises a base structure extending continuously at least along said sequence of symbols, and discontinuous discrete light-absorbing portions locally applied onto or formed at surface of said base structure; wherein discontinuous discrete light-absorbing portions form light- absorbing surfaces and base structure forms light-reflective surfaces outside surface areas occupied by discrete light-absorbing portions; said discrete light-absorbing portions are arranged to provide a lower light-reflectivity than portions of base structure outside surface areas occupied by discrete light-absorbing portions.
EFFECT: use of said optically readable support provides reading of information during rotation of capsule, which increases rate of beverage preparation process.
