A beverage preparation system comprising :
(i) a capsule (11) with side (16), bottom (18) and top (14) walls, said capsule having a shape that is substantially symmetrical around a vertical axis, and said capsule is suitable for containing a beverage preparation ingredient to be dissolved, and/or infused, and/or extracted under pressure, by action of a fluid circulating into said capsule through said ingredient,
(ii) a beverage preparation machine (1) suitable for receiving said capsule (11), and circulating said fluid into said capsule,
(iii) optionally a capsule holder (9) for holding said capsule (11), at least at the time said capsule is disposed into said machine, characterized in that :
- the machine (1) comprises a linear barcode reader (21) suitable for reading a linear barcode sequence (25) contained in a segment S having a segment length L R , said linear barcode reader (21) being disposed in the machine such that it can read a barcode printed on the capsule while said capsule is being inserted inside said machine, and
- the capsule (11) comprises a barcode sequence (25) that is repeatedly printed along a peripheral path of the capsule, each sequence being disposed in an arc having a linear projected length L S that is inferior to L R and said sequence (25) is composed of dots (26) spaced apart from one another along said arc, such that their projected point images along a linear segment are also spaced apart. |
