Method for recycling one-time codes for individually marking individual products ( 11 - 15 ), the codes being each stored in a RFID tag ( 91 - 95 ) or encoded in the form of a bar code, including the following steps: determining that a one-time code individually marking a product ( 11 - 15 ) that no longer needs to be traced is available, offering said code for individually marking another product. With this method, one-time codes can be recycled independently from their carriers such as for example RFID tags or bar codes and sold to buyers interested in new codes. |
