The all in one scanner pro app contains the following features:
- Scan Documents and convert them into a PDF and share immediately via social media sites/ email/ whatsapp
- Scan QR Codes
- Scan Bar Codes - (To scan barcodes you need to click Barcode Scanner and then click Scan at the top of the App)
It is a free app and will remain free forever.
I have used this app a few times with no issues. Great job!
