A manual batch coder 8-digit automatic numbering machine is a piece of machinery used to automatically number documents, products, and materials according to set parameters. It is typically manually operated using an alphanumeric keypad to input the desired codes, and it prints the numbers onto tags, labels, or directly onto the material itself. The machine has a built-in display that shows the programmed information and a printer to produce the desired format of the number, either as a barcode or as alphanumeric characters. The 8-digit number can be used to identify particular batches or to date individual items made in an ongoing production.
