Abstract: A merchandise transaction system and data reading device capable of gathering statistics of overall consuming detail data are provided. The data reading device comprises an input interface, a display interface, a data collecting processor, and a plurality of connecting ports. One end of each connecting port can electrically connect to the data collecting processor, and the other end thereof can selectively connect to a data reading module. When the consumer performs consuming transaction, the consumer can provide a plurality of identity identification elements to multiple certify to be benefit to complete the consuming behavior. The data collecting processor has a data storing interface for recording a single consuming detail data and sending it to a statistics unit which can collect every single consuming detail data to gather statistics, store, or analyze to obtain overall consuming detail data of the consumer.

Abstract: A data accessing device with multiple verification functions and a verification system are provided. The device comprises an electronic certificate reader and a radio frequency signal reader in an outer housing. The electronic certificate reader can access an electronic certificate displayed in a portable electronic device of a user through an optical path, while the radio frequency signal reader accesses a personal radio frequency identification label of a user through a radio frequency path. The electronic certificate data and personal radio frequency identification label data is sent to a verification system to be processed and compared with user data stored in a user database to determine whether the access electronic certificate and personal radio frequency identification label are correct or whether there is a corresponding relationship therebetween.
