Description
A very simple app that does nothing more than conveniently store and display PDF certificates. You can use it for public transport tickets, bills, contracts, certificates and any other PDF file.
The PDF file has to be imported into the app. Following that, the barcode is displayed in fullscreen, as well as the PDF document itself. That's already it.

Currently supported barcode formats are:
- Matrix (2D) codes: QR, Aztec, DataMatrix and PDF417
- Linear (1D) codes: UPC-A, UPC-E, EAN-8, EAN-13, CODE-39, CODE-93, CODE-128, ITF and Codabar
