In the Kryptofolio Import tool select the csv file and click Generate.
The Kryptofolio Import tool is available here.
This will generate the QRCode batch.
You can then select the QRCode Import screen on the app.
In the QRCode import screen you can capture transactions by selecting "QRCode Capture" this will take you to a capture screen which you can then visually point at the QRCodes you generated using the Kryptofolio Import tool.
You can then either go direct to the unclassified transactions screen to assign the correct transaction types and hence tax levels that you have configured in the tax setting screen.
Or you can go to this screen later from the transactions tab, note if you have unclassified transactions there are various visual clues throughout the app where parts of the data in various places will be shown with grey text.
This method has the benefit that you have not transmitted the transactions via the internet thus achiving the maximum level of privacy and security from hackers etc..
