In China, more and more people choose to shop online.A courier may be responsible for more than 200 parcels a day.Due to so many parcels, the couriers have to send short messages to notify customers to come to a certain place and sign for parcels, which is inefficient and error-prone.This parcel label with a two-dimensional code can help a courier generate a associated short message by scanning the two-dimensional code ,and send it directly to a customer to sign for the parcel.
