When you click on one and the same button.
On the first page displayed when loading a field to enter a number and after pressing the
save this number must be converted to a QR-code and bar code (in the form of images or css)
and displayed on the second page as a QR-code or bar code and stored locally.
the first page to the input field should not be displayed but instead automatically open the second page.
