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 scanner
because 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 generated
on the display that you can use by having your barcode reader read it at the cash desk
thank you all and good luck.
