The disclosure relates to a method, computer program product and system for decreasing the risk of erroneously handling a tool in a machine operation. The system includes a reader device for reading a machine readable code arranged at a tool part and an electronic device having a processing circuitry configured to cause the system to receive desired operation data indicative of a tool part to be used during the machine operation. The method includes the steps of receiving desired operation data indicative of the tool part to be used during the machine operation, detecting the identification marker at the tool part, reading, by the reader device, the machine readable code of the identification marker, identifying the tool part, and determining if the identified tool part corresponds to the tool part according to the desired operation data, the identification marker being a machine readable code associated with the tool part.
