description The invention relates to a method for verifying a time-sensitive and/or temperature-sensitive indicator for marking perishable products. According to said method, the time at which the indicator is activated is detected and stored, the time difference between the stored activation time and a verification time is determined, and verification is made as to whether the change of the indicator occurring during the determined time difference exceeds or falls short of a desired value that depends on the determined time difference. The invention further relates to an indicator for carrying out such a method.
