Although the present era is not as convenient as the later generations,
it does not have the identity documents and household registration books of later generations, but this era also has things unique to it.
Everyone has something similar to a household registration booklet, which is used to prove their identity.
If these people want to go to other places, they will have a passport, which is a government-issued pass. Without this, going out will lead to arrest, and these merchants all have this item on them.
Nowadays, these items have become this: a certificate for storing silver, and only with it can one verify their identity.
Not only that, because later society has everything, this era's forestry also equips everyone with a camera, each bank has a thing specifically for taking pictures, and a computer, a system that serves the bank.
