To avoid malfunctions, it has proven useful to provide such portion capsules with mechanically and optically readable, detectable identification codes so that before the start of the brewing process, a check can take place as to whether the inserted portion capsule is compatible with the machine. In addition, if necessary, a suitable brewing program can be started for the raw beverage material located in the portion capsule. It is known from publications EP 3023362 B1, WO2020/201487 A1 and US Pat.
