Claim 20:
21. A coffee machine, comprising:
a capsule container, configured to hold a capsule;
a liquid injection probe;
a barcode reader, comprising:
an image sensor, configured to optically sense a sensed image; and
a processing circuit, configured to determine if a closed shape object exists in the sensed image, to identify a code region within the closed shape object in the sensed image, wherein the code region comprises at least two different types of information which represents code information of the code region, wherein the processing circuit generates code information according to the information;

wherein a decoding direction of the code region is not relative to the closed shape object;
wherein a plurality of barcodes respectively comprising the closed shape object and the code region repeats around a top surface of the capsule;
wherein the liquid injection probe and the barcode reader faces the top surface, and a distance between the barcode reader and the top surface allows the barcode reader to read at least one complete barcode.
