At present, many strictly managed properties do not allow couriers to enter. Is there any solution?

It is difficult for property companies to distinguish whether there are criminals who use or disguise couriers to engage in criminal acts.

The reason why 1 is not allowed to enter is to take precautions from the owner's point of view, and would rather kill 1000 by mistake than put one in. The second is the performance of backward technical means.

As long as the courier company and the property company sign a cooperation agreement, it will be a good solution. It should be noted that 1 cannot make trouble for the property, otherwise the property will be charged. 2. It has strong distinguishability, such as property punching machine (usually with punching machine) to input the fingerprint of the courier into the community. With the letter of introduction issued by the courier company, record the courier's fingerprint on the letter of introduction. Once the courier is replaced, re-open the letter of introduction.
