When composing products by combining multiple products, you can use it to prevent product differences by registering the barcodes of the products to be combined as a master and collating them.
Since the master code can be set as non-required, it can be collated regardless of whether the product is included in the configuration as an option.
When using a Bluetooth-connected reader, it is necessary to set the reader to SPP mode and set the data termination to "CR + LF".
