Communicating a classification of a consumable product

A print cartridge;

• comprising:
• a storing engine to store:
• information regarding a classification of said print cartridge, wherein said classification:
• is indicated to be from a trusted source with a digital signature stored in said print cartridge;
• and
• indicates whether the print cartridge is authentic;
• and
• hardware security authentication data that, when authenticated, triggers authentication of an identifier for a print cartridge;
• and
• a communication engine to communicate said classification to a device during an authentication session with said device after the identifier which is unique to said print cartridge is determined to be genuine and from a trusted source, wherein said classification provides data to deliver an upgrade or added function of said device.

An integrated circuit for a print cartridge to communicate with a processor of a host printer, the integrated circuit comprising:

• a non-transitory computer readable storage medium and a processor of the print cartridge, the medium to store information regarding a classification of a print cartridge in a digital signature, which classification information expressly indicates whether said print cartridge is to be authenticated;
• the processor of the print cartridge to:
• transmit hardware security authentication data that, when authenticated, triggers authentication of an identifier for the print cartridge;
• responsive to a determination that the identifier which is unique to said print cartridge is genuine and from a trusted source, exchange information about said digital signature with a device during an authentication session in response to connecting to said print cartridge;
• and
• communicate said classification to said device during said authentication session such that said classification triggers a function of said device, wherein said classification provides data to deliver an upgrade or added function of said device.
