1、 Product design primary need and background
1>、Portable terminals: support writing by hand and numeric keyboard input;
2>、integrates the second generation of resident identification card reading machine and tool: can integrates the second generation of resident identification card reading machine and tool in the product, the second-generation card have existing board，dispense with research and development, only need the serial port connection, then may distinguish the second-generation ID card information; But, because the second-generation ID card board and security module volume is big, is impossible to place portable equipment, therefore, need a section tabletop, can integrate with research and development board, existing board and security module;
3>、Uses set of boards to be able to produce at least two model of products
2、Product appearance structural design plan(portable)
