The random value is automatically generated by the device and must be changed only once after the consumables are replaced, and the value is different from any previously used value.

[0008] S2. After replacing the consumables, the device concatenates the URL, device SN, and random value to generate a QR code;

[0009] S3. The user scans the QR code with a mobile phone and enters the activation page. At this time, the server can obtain the device SN and random value;

[0010] S4. The user needs to fill in the consumable SN on the activation page, and the server will determine whether the consumable is genuine and whether it has been used;

[0011] S5. If it is genuine, the server will concatenate the device ID, random value, and key, use the secure hash algorithm to generate an activation code, and display it to the user;

[0012] S6. The user inputs the activation code into the device, and the device generates an activation code in the same way and determines whether it is consistent with the user input;

[0013] S7. If they are consistent, the activation is successful and the consumables are genuine.

[0014] Preferably, the QR code generated in step 2 is random, and after the consumables are replaced, the original QR code becomes invalid, and a new QR code is automatically and randomly generated.

[0015] Preferably, in step 4, regardless of whether the consumables are genuine, a pop-up window will be displayed on the activation page to remind you, and the activation page will prompt whether the consumables SN filled in is correct.

[0016] Preferably, in step 5, the hash algorithm maps a binary value of arbitrary length into a smaller binary value of fixed length. This small binary value is the hash value. The hash value is a unique and extremely compact numerical representation of a piece of data. A 5-byte hash value is generated using the hash algorithm, and an activation code of 8 characters is generated using Base32 encoding.

[0017] Preferably, the activation code entered in step 6 is not case sensitive.
