It is a reader of QR Codes (QRCode) and Bars (BarCode), which also allows generating code from a desired text.

You will be able to click the button to read the barcode and qr and, once read, you will be able to open the content read in the browser, copy to paste wherever you want or open directly in the browser (if it is a navigable URL)! You can generate a QR code from a text to use as you wish! In addition, it records the history on the cell of the readings read for later use, in case you need it (you can delete it, if you prefer!)
