- a dynamic barcode display device uses a communication means to dynamically generate barcodes based on numerical values transmitted and received, and to combine per-code images created on the database side. Barcode display can be performed on the screen.
- a dynamic bar code display device always displays the bar code display position at the same position, so that when reading with a per-code reader, etc., multiple bars can be moved without moving the reader.
- the code can be read and the reading time can be shortened.
- the dynamic per-code display device adds a code indicating the order to the per-code, so that the bar code reader can read the bar code based on the code indicating the order at any time when reading is started. By reconstructing the code order, it is possible to make the reading device obtain accurate numerical values.
- a dynamic bar code display device performs calculations based on numerical information of some or all bar codes, and adds the calculation result information, in the same way as the check digit used as a standard for bar codes. Therefore, after reading all the barcodes, it is only necessary to calculate the numerical information of some or all of the barcodes and check whether they match the result information, and read one barcode. Since it is possible not to calculate the check digit displayed on the bar code every time, the time can be shortened.

- the dynamic barcode display method is to calculate based on the numerical information of some or all of the barcodes and add the calculation result information in the same way as the check digit used as standard for the barcodes. After reading all the barcodes, it is only necessary to calculate the numerical information of some or all of the barcodes and check whether they match the result information. Every time a barcode is read, It is possible not to calculate the check digit displayed in the parcode at the same time, so the time can be reduced.
- the dynamic per-code display method is composed of, for example, 1 3 digits + 1 3 digits + 8 digits by adding a code that represents the code delimiter when generating a barcode or sending / receiving barcode images.
- the read parcode is read and reconstructed by the reading device, the numerical information read is divided and handled according to the delimiter code. Can also represent accurate numbers.
- a parcode is generated based on the previous successful communication record stored in the storage means. By displaying the parcode, even if the communication is not possible, it can be displayed as a temporary barcode.
- the barcode data volume is increased by displaying at least 2 bar codes continuously, and the data is displayed dynamically, so it can be easily duplicated. It is possible to display difficult bar codes.
- a plurality of bar codes can be generated from arbitrary numerical information based on the numerical values, and the bar code display can be performed dynamically.
- the communication program When the storage medium program is executed, the communication program must generate dynamic per-code based on the numerical values sent and received, and combine the barcode image created on the database side. Thus, bar code display can be performed dynamically.
- a code indicating the order is added to the bar code so that the order can be displayed whenever the percode reader starts reading at any timing.
- a dynamic expiration date can be set by adding a time method when a barcode is generated or when a barcode image is transmitted / received.
- a certain period of time elapses when the barcode creation time is compared with the current time. It prevents the duplication of bar code such as making it unusable when using it.
- a code indicating a code delimiter is added when generating a parcode or when transmitting / receiving a parcode image. For example, 1 3 digits + 1 3 digits + 8 digits When reading and reconstructing per-codes that have been configured with a reader, by dividing and handling the numerical information read according to the delimiter code, accurate numerical values can be obtained even for bar codes with different numbers of digits.
