With the accelerated process of economic globalization, the modern logistics industry shows a steady growth trend, bar code technology in the cargo management has been widely used. The market for wireless bar code collection terminal needs increasingly prominent. For now, several wireless communication methods will be concentrated together bar code acquisition terminal is relatively small, and expensive. In addition, in the process of transmitting the bar code data, the bar code data to be transmitted is not effectively encrypted, and the bar code data is likely to be leaked. In this paper, we design and implement a wireless bar code acquisition terminal, which integrates GPRS and WiFi wireless transmission methods and encrypts the bar code data using DES algorithm to solve these two problems effectively.
