Problems solved by technology

Although these portable devices also integrate barcode and radio frequency identification functions, due to size limitations, either they cannot realize the function of wireless transmission, or they cannot provide a large main optical module system, and they cannot be conveniently placed on the desktop. Manual operation is more expensive
More importantly, in some security verification applications, it is necessary to collect user information and read invisible barcodes. There is no convenient solution for existing technologies

The device has low cost, simple use; study-read can be finished by simple fixation; and user photo function is provided. The automatic bar and RFID detection, combining state designation, can realize the application in the unattended situation; and radio data transfer can be realized.

Description

Technical field: [0001] The invention relates to a data collection and processing device, which belongs to the technical field of radio frequency data collection and bar code reading. Background technique: [0002] With the improvement of social informatization, barcode and radio frequency reading, as two important means of automatic identification, have been widely used in various applications. The advantage of radio frequency identification technology is that it can realize long-distance multi-tag automatic identification even in a fast-moving state in a non-contact manner. However, radio frequency identification technology is still relatively difficult to improve the reading rate and quickly find missing objects. In addition, the promotion also faces the problem of high cost. Barcode identification technology can be a supplementary means to solve these problems. Among them, two-dimensional barcodes have large information capacity. , low cost and other advantages, it has ...
