The cloud creates a "written" QR code for each customer. However, this cannot be read by the GASTROFIX app. To create one or more QR codes, there is an easy way with Google Docs to prepare the QR codes for your print shop.
Procedure:
1. Download the customer file from the cloud via "Download QR Codes" under "Operator" --> "Customers" --> "Download QR Codes".
2. Copy the contents of this file into a Google (Excel) document
Select a free column and enter the following function:
=image("https://chart.googleapis.com/chartchs=150x150&cht=qr&chl="&A2)
For "A2", the cell of the "written" QR code e. g. 01a5a5c4-e6e5-4ded-871b-e2c41eb4304d must be specified. (First column of the downloaded file)
The most important thing is that the finished table with QR codes must be exported as *. pdf, otherwise the QR codes will disappear again.
Considerations
Basically, the QR code is created with this method. The height and width of the individual lines must still be adjusted so that they are displayed.
The QR codes created in this way work with our app without any problems.
