A method (200), apparatus (100, 300, 600, 700), system (1100) and computer program is disclosed. A first signal (102) comprising a first code (103) representing a composition of a first material (306, 602) is received from a first source (301). The first code is compared to a second code (104), generated by analysing the first material, to determine if the first code matches the second code. A first output (105) is provided, indicating that the analysed first material is verified as being the first material, only when the first code matches the second code. Weighing of the first material is enabled, dependent upon the first code matching the second code |
