Hi,
I work in a ticketing company and we used Wallet passes.
Everything works great but some venues report that some qrcodes are unreadable.
I have one example. All information is present but the qrcode could not be read. We tested multiple readers.
The information in the qrcode is only numeric, so ti is not an encoding issue.
What can cause this issue ?
Here an example of incorrect generated qrcode : https://drive.google.com/file/d/1uoRE6-d5OhSK2HjsT71jG4LcDXlrM4eg/view?usp=sharing
My iPhone camera scans it as valid but doesn't show anything. Other application scan it as empty... did you try to unzip the .pkpass file and check the barcode field if it actually contains something?
