Mobile device

A network component comprising:

• an information database comprising decoded information obtained from decoded data codes and authentication information obtained from an authentication operation performed on data codes;
• a training entity adapted to generate a prediction model based on the decoded information and the authentication information;
• and
• a communication entity adapted to send the prediction model to a mobile device to update a processing entity in said mobile device.

A method for operating mobile device, comprising:

• capturing a data code associated with an item;
• determining whether a captured data code is authentic and generating authentication information as a result, and decoding the captured data code to obtain decoded information;
• sending the authentication information and the decoded information to a processing entity which receives the authentication information and the decoded information and generates, based on the authentication information and the decoded information by using a stored prediction model, an indication for a next code to be captured;
• and
• outputting on a mobile device information relating to an item and location associated with said next code to be captured based on said indication.
