英文摘要：

To assist couriers in sending messages to inform customers of getting their packs automatically, quickly and exactly, an express auxiliary software named ＂All inclusive scan ＂ is designed. The design is based on the device of sending informed messages automatically, which is controlled by 51 single chip microcomputer. Firstly, Freebarcode is used to transform consumers＇ telephone numbers into bar codes. Secondly, they are scanned to send information to 51 single chip microcomputer by scanner. Lastly, 51 single chip microcomputer sends bar codes to GSM module through AT orders, meanwhile, sending order is delivered to GSM module to complete informed messages dispatch. With low cost, such device has high practicability and flexible expansion of the circuit.
