Research and Implementation of XPE-based Embedded Coal Sales Ticket Control Terminals

Recently,manual work of sales ticket,including data entry,statistics,accounts and verification,is adopted in coal field.This brings about many problems like heavy workload,low efficiency,especially ticket lost, long period of recycling process,and data transmission and verification fraud provoked by interest in grass roots authorities.For solving these problems,this paper proposed an implementation scheme of Coal Sales Ticket Control Terminals that is based on XPE embedded operating system.It adopts many security technologies,including USBKey-based authentication technology,authenticity of two-dimensional barcode control technology,encryption and decryption technology of data transmission etc.Finally,it makes the system more secure,stable and reliable.
