  • a sensing device for sensing coded data printed on a print media surface, the sensing device being installed with a secret key and a first identifier which uniquely identifies the sensing device;

    a printer being installed with a second identifier which uniquely identifies the printer; and

    a server being installed with the first and second identifiers,wherein the printer is configured to obtain the first identifier from the sensing device and communicate the first and second identifiers to the server,the server is configured to determine from the received first and second identifiers whether the sensing device should be registered with the printer and if so, to authenticate the sensing device by verifying an encryption from the sensing device, using the secret key, of a challenge message, andupon successful authentication, the sensing device being registered in the server so as to be associated with the printer.
