We are having issues with the QR Code generator due to its 2.1 version of the VCARD. Not all readers and phones interpret that correctly, resulting in parsing errors depending on the scanner software used. It would be useful to allow the user to select which VCARD standard they want to use, such as VCARD 2.1, 3.0, 4.0, etc. This will create the metadata to be compatible with more current versions of scanning software. Not sure if version 2.1 is deprecated, but it's not always supported anymore (e.g. RedLaser, etc) causing parsing issues on the address line with iOS as an example.
