The package of the passport express says "Please sign my name in the signature column of the holder after receiving the passport". Before the e-passport was issued, the last page of the back cover of our ordinary passport had the signature column of the holder. That sentence is equivalent to reminding you not to forget to sign. Because in foreign countries, some departments will compare your signature style with your passport signature style to judge whether you are a holder or not.

E-passport does not need your signature, because you have been asked to collect your signature sample when you apply. Your signature is already in the lower right corner of the e-passport information page. The small square on the last page is the electronic chip logo, reminding you to stick the electronic chip and keep it carefully.
