I think it's more interesting asking for a (large) Qr code who encode: - sender data - recipient data (POSSIBLY GPS etc included) - paid fees Aside of any human-readable information. That's might simplify shipping process much and allow quicker operation between different countries address formats having a "QR generators platform" who take care of the differences up front. For instance generating proper human-readable addresses for both sender and recipient locations according to local postal service rules.
