This app allows you to create a text QRCODE on the fly,or an ean 128, created mainly when a code does not go through the scannerbecause it is ruined, and you cannot type it because it contains both letters and numbers,in that case you type it comfortably on your smartphone and a code is generatedon the display that you can use by having your barcode reader read it at the cash deskthank you all and good luck.
