There are 3 common problems:
1. Senders don't know if the other side has recieved the letter;
2. It's a huge waste of paper of envelopes;
3. People can't protect the privacy like address and name;
This design use 2D-code envelope to get through these problems. The code could be re-write, nobody would know the exact address except postmen, and as soon as reciever scan the code,
sender would be informed.
