Abstract

The present invention relates to a barcode display device with data processing function. The barcode display device is provided with a control device connected to a display screen. The control device is provided with a connection interface electrically connected to a host terminal, and the connection interface is connected to a microprocessor. The microprocessor is connected to a display driving control module, and the display driving control module is connected to the display screen. When the user intends to receive data of the host terminal, the host terminal first transmits data to the microprocessor, and the microprocessor converts the data into corresponding barcode signals and uses the display driving control module to control the display screen for displaying the barcode corresponding to the data, so that the user can use the scanner of a barcode scanning device to scan the barcode displayed on the display screen for being stored into a storage device.

Description

1284287 Shop vendors have the most major currency or electricity, self-help or range. In the technical field of 'and' for the reconciliation of the smugglers and retiring business in the field, in order to provide information on the host side of the data, and display the bar code display device of the display The bar code display device of the function function is gradually becoming popular due to the conversion of the data into corresponding articles. In particular, the no-store sales of the type has been driven by the vendor law or the unmanned device, and the specific transaction is completed to complete the goods or services. The sale of musical instruments, luggage storage, automatic ticket sales, and merchandise sales all belong to the street and alleys can see the trend of automatic sales. It not only provides the consumer with a sales channel for augmented goods, but the coin device or the banknote receiving device does the identification of coins or banknotes for counting coins or banknotes. Waiting for the salesman to complete the processing of the company, however, the money received by the tube selling device, and the invention description (1) [The invention belongs to the invention, especially the receivable code and is displayed in [previous technical press, no marketing expert Gradually formed, its vendor law. |Media, such as hard 'such as the gas station when the parking lot, such as the parking lot, the establishment of the recent installation of the convenience of its future city and the use of money for money, stop, prevent, however, the sale of equipment for post-recording The method needs to be sold under the planning of information technology. Everyone is discussing the use of automatic trafficking records, etc., laundry, electric drinks, food, and the growing number of battalions across Taiwan are also quite large. The potential selling device is based on investment, these control is out, and the management, department, collection, maintenance, and reunion are brought back to recycle the vending
