1st check: scan/inspection of the Digital Covid Certificate (as a QR code in the Covid app) and comparison with your official identification document.
2nd check: security check of persons and luggage
3rd check: scan/inspection of the digital ticket (as a QR code in the trade fair app)

At the entrance to the trade fair grounds, the Digital Covid Certificate is first checked using the QR code in the respective Covid app. After that, the usual security check of persons and luggage, e.g. of the bags, is carried out. The trade fair ticket located in your trade fair app as a QR code is then checked at the turnstile.
