If you look closely, you will find that every SF Express courier has an electron gun. When we deliver the courier, the courier uses it to scan the courier's barcode and transmit the data synchronously. This work detail greatly maintains the safe delivery of couriers, and also widens the service gap between SF Express and other silent courier companies.

The "Ba Gun" system uses the mature network platform of China Mobile, takes the mobile phone or PDA terminal as the carrier of data storage, and connects the barcode scanner to form a set of data acquisition and transmission system. The implementation method is to connect the external scanning gun to the mobile phone that supports the function of "Ba Gun" through data cable or direct connection. After the goods are delivered to the customer, the field staff first scans the barcode on the waybill number, and PDA/ mobile phone is used as the carrier of data collection to store relevant information, such as the customer's name, receiving time, goods status, abnormal information, etc., and can use the customer's electronic signature receiving function to update the receiving bill and electronic signature in the background system in time.
