First, enter the WPS office software system, create a new blank document, insert a box with a length of 9CM and a width of 5CM with the text box tool as the size of the library card, and then modify it as needed.

Then you can enter the text information needed in the library card in the text box, and then select the font, font style, font size and font color as needed. Then click the barcode command under the Insert menu with the mouse to open the barcode editor. At this time, you can choose the barcode standard. The barcode function in WPS supports six barcode standards: UPC-A, UPC-E, EAN- 13, EAN-8, staggered 2/5 and Code39. Here I choose "EAN- 13 standard. Click [OK] to adjust the width, height and color of the barcode. If you are not satisfied, you can right-click the barcode and select "Properties" to modify it.

Now make a bar code library card. If mass production is needed, it can be saved as a template file.
