Reception-transmission exclusively by SMS code. You don't sign anything, you don't provide any documents. On the one hand, it is convenient - without bureaucracy, but there is a risk that someone else may pick up the parcel. It will be especially insulting if someone picks up a paid parcel.
Maybe it makes sense to implement two-factor protection, something like:
You came for the parcel, showed the code, after which you are told that an SMS will be sent to the contact phone (of the recipient) with a confirmation code about the receipt of the parcel, which you will need to inform the operator or enter yourself. Entering the code (sent to the contact phone) will be a confirmation that the parcel has been received.
The location is good, it is not difficult to find by the road (on the right side of the museum is the city of Ferghana), the room is uncomfortable and cramped.
