摘要

A machine readable identification on a portion pack containing coffee powder for espresso machines, designed so that it can be read easily and accurately, is structured in a rotation-symmetrical manner and is applied to an essentially level surface of the portion pack, whereby the portion pack preferably consists of a portion capsule (1) having an essentially circular base (2) whereupon the identification is applied in a coaxial manner.
