Abstract
The invention relates to: A method of providing an electronically readable item of information (725) on a medication cartridge (70). The invention further relates to a cartridge (70) containing an electronically readable item of information (725), a support (75) for reading the information (725) on the cartridge (70), a medication delivery device adapted to use a cartridge (70) and a support (75) according to the invention and a label (72) containing an electronically readable item of information (725). The object of the present invention is to provide an alternative method of generating an electronically readable item of information on a cartridge which method is simple and improves safety in reading. The problem is solved in that said item of information is redundantly provided (725, 726). The invention may e.g. be used in connection with medication delivery devices for self-treatment of a disease, e.g. diabetes.
